[@GamersNexus]

Article with a couple extra charts and the intro/conclusion written out: www.gamersnexus.net/hwreviews/3157-intel-i5-8600k-review-overclocking-vs-8700k-8400 FYI, the R5 & R7 CPUs just went on a bigger sale than before (happened after we shot the video): www.gamersnexus.net/sales/3156-amd-ryzen-cpus-cut-to-even-lower-prices-r5-r7-r3 You might also like our Best CPU round-up: www.gamersnexus.net/guides/3130-best-cpus-of-2017-round-up-gaming-blender-premiere

[@ArthurGomes]

I wish to see a similar test but using a radeon gpu, to see if there is any chance in the stack, mostly because of the "nvidia driver overhead" thing

[@imanny99]

Gamers Nexus can you compare the 8600k against the 8700k (and maybe R5 1600 and R7 1700) for gaming and streaming

[@haris6224]

I got my 8600k on the same board to 5ghz stable at 1.32v. Why did you need to go that high with your v core

[@cataria3903]

is there a reason cinebench r15 wasn't tested or did i miss that? i really like cinebench to see how much multithreaded power chips have or how good the chips may scale into the future and gn is one of the places i usually use to find numbers to compare cpus at a later date too. so please ad cinebench again, i can't compare your blender benchmark to my cinebench benchmark and yes i know i know, different cases, ram speeds etc.. etc... but i really like to have cinebench r15 at least in the article, please.

[@sm6081]

Haris silicon lottery duh.. ur chip was better

[@SagratHGR]

I've been watching your review videos for a while now and ive always been impressed by the quality and the amount of info you provide the viewer regarding every little aspect of the product. How come this channel is only sitting at 200k subs? You deserve way more ! A fellow PC enthusiast and engineering student .

[@Najvalsa]

Nice to see a return to form for the i5's as the CPU choice for gamers, instead of that being the i7.

[@Deletistjerk]

But at a $300 price tag, it's like buying an i7

[@Najvalsa]

True, true. But i7, i5, i3, Pentium, 8600, 8700, all of that is just names. You can look at it another way and see it as better than the 7700K for $50 less, although I personally wouldn't consider it above $280. Either way it's still $100 cheaper than the 8700K, but Coffee Lake pricing is all over the shop right now, as we know.

[@nietrelevant3338]

Yeah people seem to forget that intel cpu prices have spiked significantly since sandy bridge, more then inflation basically. So although its nice that intel finnaly added more cores after amd launched ryzen they were basically allowed to bring their i5 prices up to i7 level in the years they had no competition. Which is basically why competition is a good thing wether you like intel or amd.

[@jondonnelly3]

The point is the money saved would move you from a 1070, to a 1070ti. Bloody big increase.

[@uncommonlogic2851]

DOLLAR FOR DOLLAR THE OC'D 8350K IS A BETTER GAMING CPU.. AT 180.00,,,,, IT'S A NO BRAINER.

[@fifthgear93]

This is why I love your reviews Steve, always very thorough and carefully made.

[@sm00419]

Had a 2500k. Was waiting on the 8700k results. Decided to wait until the next release...mostly because of financial situation. Got a 2600k for $120 on Ebay and sold my 2500k locally on Craigslist for $65. I got significant gains in FPS in a lot of the games I am playing for $55. Sure jumping up to a 8700k would have doubled my performance gain...but it would have cost me $700+ more to upgrade the CPU mobo and RAM.

[@toppsballer]

Smart man.

[@nomadace777]

Here from the future, just built a i5-8600k x 1660 ti 16gb 1TB m.2, runs very well!

[@Wings_of_foam]

Hey, i58600k, 1660 phoenix, 16bg let's go haha!

[@AB21]

I5 8600k and 9600k are still the kings of gaming in price for performance.

[@wyattmathis4854]

Intel and amd really need to stop making similarly named chipsets

[@mapesdhs597]

From their point of view, it can be an advantage, luring people in who might misinterpret a name. Potentially deceptive, but then it's still up to the consumer to make a sensible purchase. Alas, for a heck of a lot of the buying public, this entire field is completely alien. Here's a line I heard a member of staff in PC World say to an older couple about a laptop they were interested in: "Yes, it does come with the latest WIndows 10 processor." My cringeometer went off the scale. The couple had no idea what all the technobabble meant, and the staff guy didn't have a clue what he was on about either (at least I hope he wasn't trying to b.s. them). In the past I've intervened when I've heard staff people say nonsense to a customer, but not this time. :D

[@dickr9345]

FWIW AMD is the one who hijacked Intel's numbering scheme. IE AMD's b350 x370 x399 vs b250 z270 x299. AMD knew Intel's next chipsets would follow that trend and be 300 series, and they jumped on it anyway. That left intel in a spot where they either came up with something different, or continued their own trend with 8th gen and just have similar chipset numbering. OTOH (IIRC) intel has done this in the past to AMD, but I could be wrong. They also kinda did it with Ryzen, R3 R5 R7 vs i3 i5 i7 but IMO that makes sense. To be clear, I'm not badmouthing AMD or Intel. Do what you gots to do to be competitive.;)

[@jort93z]

AMD just tried trolling intel i think. Inten did B150, B250 and then AMD just released B350 to troll them. People at intel HQ were probably quite upset and had to change the name of it.

[@sm00419]

@Gamers Nexus Would really love to see you include Sandy Bridge/Ivy Bridge results in the article/videos. There are still a lot of folks running 2500k - 3770k's out there that haven't felt the need to upgrade and seeing the performance gains in various games would be nice to see what the performance gains would be. I know you have specific videos on this but X person who may have one of those cpus and thinking about buying Y cpu you are covering may not. Even seeing it with a separate graph at the end of the video or article would be tits. Keep being awesome.

[@rodolfoboimarinho6504]

they made it with the 7700k and you can check on the website a list with them all.

[@DrMice760]

This has been done but i forget by who

[@Brandon-yx9qy]

Still running an 2500k, and a 7950 here! Starting to stutter on certain games, but I get around 90 FPS in Los Santos in GTA V, and around 120 FPS in the dessert, with mostly very high settings. Got a few things tweaked here and there. Rise of the Tomb Raider averages 54 FPS with drops to the 12 FPS range with everything on ultra. Extremely playable, never experienced the drops to 12 FPS while actually playing the game, just during the benchmark, no stutters or anything during game-play. Overall, i'm surprised that i get the performance i do still. But I really need to upgrade. If i'm running a youtube video on my second monitor and playing a game my CPU is almost pegged out for the majority of the time. I'm waiting for Canon lake, want to see what intel brings to the table with that, but i've put some serious thought into getting a ryzen system, killer performance per dollar.

[@TY1979KA]

I bought an R5 1600 and use it mostly for gaming but also for image analysis, what i learned so far: if there is any workload utilizing threads, it pays off to save the difference in money. Its not only the CPU but also the boards. I bought a Asrock AB350M PRO4. In total less expensive saving 200+ bugs in total. This way you can get a 1080ti instead of a 1080. That made much more sense to me. If u have no budget go with the Intel CPUs.

[@TY1979KA]

I stopped replying to comments like his long ago, ... no need to invest time

[@MujoNovak]

its Bucks not bugs LOL

[@fireberries9540]

now my 7700k friend can stop flexing on me

[@Watchmetry-nn9xe]

It's Sept 2020 and my 8600k is still going strong, running new games without a problem, able to multitask with games and web browsers open and it has not lag a single time

[@Watchmetry-nn9xe]

@Joseph L i5 9600k are $300 with a motherboard at micro center. That's the same price i paid for my 8600k.

[@jacquesahlers2253]

i5 8600k + cooler + z370 + gtx 1060 costs the same as r5 1600 + cooler + b350 + gtx 1070 Ti I know what I would buy.

[@jacquesahlers2253]

Nope, I already took the included cooler with the R5 in my calculations so 1070Ti it is but still an obivious choice for me.

[@BeastOrGod]

Pentium G4560 + no cooler + b250 + Titan XP I know what I would buy

[@sneakeyboard8305]

1900X + 380usd mobo + expensive GPU + KVM - Windows - liver I know what to....wait.

[@ajirarevani3185]

Ryzen 5+Gtx 1070 will perform much better.

[@chaos_deus0394]

There is no need for a cooler with ryzen 1600 unless you are getting the 1600x what would be a better choice would be depending on the price of the cooler getting a gtx1080 or 1700

[@Reesecup1200]

I would love to see a stream comparison with 8600k vs 1600x or 8700. Honestly I just want the streaming numbers for 8600k. Thanks!

[@dongurudebro4579]

Well in case of Streaming the 1700 should be a no prainer vs Intel! Btw you cant really do reliable streaming test...

[@alecbramlett]

That really depends on which streaming application you choose. Some are computer melters.

[@killacamfoo]

At nearly 80*C you should still Delid, that temp will decrease the longevity of the chip if run at sustained workloads.

[@michaelross6579]

6core i5 is a good step forward away from quads.

Michael Ross 🙂 yup the 8400 & 8700 shud b the minimum

[@Str8upWizardCJ]

Lofty Smalls that rumor seems unreliable wouldn't expect it.

[@Str8upWizardCJ]

WarmSoftKitty well if the rumor is true and the i7-9700k is 8 core it will be on the 14nm++ architecture however Intel has been working on 10nm and for them to push it out even further is both doubtful and troublesome. Reasonably Intel anticipated that ryzen would be better than it was and had moved toward developing coffee lake the way they did. The i7-8700k is a misstep imo.

[@xPlatiinHD]

"Intel lost almost 60% market share to Ryzen". Do u have any clue what ur talking about?!

[@xPlatiinHD]

Lofty Smalls you have too much time

[@ForzaE2]

I came from future. I bought my 8600k after watching a couple of videos including this one. I made the right choice.

[@thirtyacres7504]

Yup. The i5-8600K and i7-8700K are best bang for buck CPUs for gaming from the Coffee Lake generation.

@@Derelict_Doug so whats your next move 🤔 i7 or i9?

[@Derelict_Doug]

@@hAvOkCrEw1 Side graded to an 8700K and it still bottlenecks in Cyberpunk. Either a 5600X from AMD or an 8c/16t from Intel would solve it.. I'm either waiting for AM5 cpus or just upgrading to a 4K monitor to remove the bottleneck.

[@chincemagnet]

How about we get some more people donating to GN? GN delivers the best enthusiast PC content period. I was surprised to see how few people offer support to this channel. Just donate $2 a month if you can afford to skip a cup or two of coffee or an energy drink every month. Gamers Nexus is better than Jay and far, far better than Linus and his juvenile crew. Let's make GN the top KZbin tech channel so they can continue to provide superior content.

[@bitmau5]

As I would expect most members of this audience to be the IT guy that their friends and family go to for help and advice, I have one thing to say; If they're confused about buying or building their own system, send them to this video. If this isn't crystal clear to them, then they need to do more research on what setup will benefit them most, based upon their needs. If they know full well what they intend to do with their rig but are are still confused over the fragmented market, this video should pretty much help them figure it out, with your help of course. Great video. This quick roundup is incredibly useful as a source of reference for those of us aiming to help others with our knowledge.

[@phoenixblaze4193]

I'm gonna buy Ryzen 5 1600X over i5 8600k. Not because of cheaper mobo but to support AMD for bringing back CPU competition to life. Intel was robbing people with their 10-15% increase scheme.

[@blackwidow7804]

From Sky Lake to Coffe Lake there is 0% IPC gain. Kaby Lake just have100-200MHz higher clocks and Coffe Lake 50% more cores/threads only thx to Ryzen. So yeah fuck Intel.

[@yeboi4079]

OC ing on the i5 does a lot more than on the i7, while an OCed i5 performs about the same as a stock i7. If you include the cost of a cooler necessary to OC and the higher power consumption, then the i7 8700 (NON-K) seems much more reasonable... and if you're just gaming it would make sense to just buy an i7 7700k with their cheaper mobos and ram prices (as long it cost about the same as an i5 8600k or less) - as long as you're not streaming too I guess. Great review btw keep them up:)

[@Rebrand_Steve]

I would love to see a Gaming+Streaming breakdown on the 8600k vs ryzen r5/r7!

[@dongurudebro4579]

@Gamers Nexus +Gamers Nexus Are you planning to do a 2500U and (vs) 2700U review? Also a replacment of those RAM-Kits (in a notebook) would be highly interesting. Would be great! :)

[@EdgyNumber1]

Good analysis, Steve. In fact i5 8600 seems great for games, perhaps i7 8700 seems great for gaming streamers the extra threads and cores might help.

[@TampaGigWorker]

I own this CPU and I'm very happy with 4.1Ghz while gaming in boost mode with a $30 air flow cooling solution. Running @ 5Ghz is just unjustified with the cost of high a end pricey water cooler/radiator to achieve 5.0Ghz. I'd just buy the i7-8700k with a $40 cooler and enjoy hyperthreading at my fingertips.

Steve what are your temps at load? At 5.0ghz with a 1.345 vcore and an llc of 5(out of 10) my temps while playing bf1 are mid 60s to low 70s. I should also mention the llc pushes my vcore upward to 1.375v. When stress tested with aida64 the temps get into the low 80s. My mb is the MSI z370 sli plus. My heatsink is the h100 v2.0. Are these temps ok?

[@xlonewolfx999]

Please could you do a video on CPUs? R5 1600/X, R7 1700/X, i5 8400, i5 8600k and i7 8700/k. A video where you compare percentage of difference CPU usage vs. Frames per second. Purpose of this can be testing CPU's potential in the future. Intel CPUs are utilized better by games vs AMD. However, say in future a game comes out which maxes i5 8400, which is already the case in certain games, then would the extra cores of Ryzen help. I got this idea while watching a benchmark video where i5 8400 was @ 100% giving out 100-110 fps vs R5 1600 @ 85% giving out 100-109. This was because 8400 ran out of juice and 1600 had a little headroom. Quite impressive on Ryzen's part.

[@lindsayhilton4835]

I was able to pick up an 8600k at Microcenter with the Gigabyte HD3 board for $260 on sale. At that price point it was impossible to pass up and there isn't anything in that price range to compete with. Also Managed to snag an Armor GTX 1080 on Amazon for $500....just have to wait 3 weeks for it to get in stock :-(

[@progammler]

What about streaming capability? Is there a significant performance drop in gaming and encoding on the CPU vs just gaming? I would like to know how much headroom the 8600k and 8700k have left for other tasks. Thanks

[@nojoojuu]

Thank You for a great video again! Is this intel platform compatible with the upcoming i9 cpu's?

[@razmuzen1090]

I3-8100 performs better than r5 1600.

[@pigdad]

I would love it if Intel kept this generation of chips within the price brackets of the previous generations. This could just be to shortages, but $300 for an i5? No thank you. Think I'll stick with AMD until Intel can price their chips competitively.

[@madokie1970]

I bought my i7 6700k with longevity in mind in 2015. With HT it is effectively 5/6 of 8600k power? At 1440p i will be GPU limited for a while (have GTX 1080 atm). It is a geat time to build a PC outside RAM prices. My pick for new pc build would be r5 1600 or i5 8400 with h370 mb (when available).

[@pablopervguy4355]

I OC my 8600k to 4.9ghz with 1.37v. But when I OC it to 5.0ghz it requires 1.45v. Is this normal in a z370 board? from 1..37v to 1.45v just to transition from 4.9 to 5.0. this seems weird

[@herbertbrown8683]

looks like the i5 is my cpu of choice thanks for the heads up great content abput this cpu and very helpful to me cause i am basicly gameing so the 8600k is my next build thanks again great review keep them coming

[@alessandrolira4035]

even then, the processor itself is powerful on its own right, it is no longer slacking behind workstation processing with processors such as the 7 1700, with Intel closing the gap considerably while keeping ahead of gaming and desktop usage. and only about $10-20 away from a 1700 that's a mighty fine deal.

Hello, I know that my comment is late but if you can please provide a feedback. I have Asus Z370-F / Intel i5 8600k / Corsair Vengenace 2x8Gb 3000Mhz / Corsair RM650X / NZXT H500(stock 2 fans) / Noctua NH-D15S - NO video card yet(1080TI on the way). My processor(stock setup - no OC yet) is at 32-34 Celsius when i browse and watch videos with integrated VGA from motherboard. Initially the temp was at 29-30 Celsius first 2 days after i mounted the PC. Should i be worried about the increase in temp? Or is just a behavior of the thermal paste settling down. I can't test yet the gaming temps. Thank you! BTW - nice videos and you got a new sub :)

[@chrisleclerc8236]

Very nice vid . Props to all the work you put in to all these reviews and vids is amazing ! . Just like every gen on intel . The I5 is the same or a minor behind as the I7 for gaming = Why I have always owned i5's spend the extra on a better GPU =)

[@mapesdhs597]

This is true at the time of purchase, but as numerous comments elsewhere here show, it tends to not hold true after a while, to the extent that many who bought on that basis initially now regret their decision. Depends on the longevity of one's typical upgrade cycle I suppose. I'm just glad I went straight to a 2700K @ 5.0, and then sideways to X79 (4930K probably at 4.6, not sorted it out yet), kinda the best of both worlds at the time (I still use both systems, the 2700K with a 980, while the 4930K will get a 1080 Ti when prices stop being crazy).

Wow, this really puts into perspective how power efficient Ryzen is. A 16 core 32 thread Threadripper using as much power as an Intel 6 core 6 thread. I purchased a Ryzen 1600 over an 8600K for my brother's rig. I saved money not having to spend $100 more on the processor, $100 just on the CPU cooler, and $50 extra for an "overclocking" motherboard cuz AMD gives you that on any b350 or above board. I took that money and got him a 1080 Ti instead of a 1080. Not to mention the money he is going to save when he upgrades to Ryzen 2 and Ryzen 3, not having to swap the motherboard out each time like Intel forces you. And guess what? The difference between the 1600 and 8600K would have been nil for him in gaming as he has a 60 Hz 4K monitor and he gains the extra cores / threads.

[@klklkl427586]

I am really interested in how long will these chips last at 1.4 vCore. I remember when overclocking sandy bridge we used 1.4 as max safe "everyday" voltage, and with every new (smaller) process node operating voltage usually drops (250nm used 2V, 130nm 1.5, 65nm 1.3). So how fast will these chips degrade, or are these newer nodes mostly bullshit (smaller in name but not much in size) like i suspect?

[@Itbankrock]

its not really the CPU that will degrade. Its your motherboard that will, especially its VRMs.

[@klklkl427586]

I am looking to update my 2500k (OC 4GHz at 1.25v since i bought it) and i am not sure if this kind of overclock will last 5+ years. Right now for me 8700 + modest motherboard and cooler looks like far better option than 8600k + oc board and a big cooler. I would really like to see 8700 vs overclocked 8600k, also is limited overclocking still a thing, earlier you could overclock non k chips to their max turbo + 4 bins?

[@ToriRocksAmos]

Always the misinformation. Yes, your CPU will degrade. (@Itbankrock smh) @kl How much? Hard to tell, since we have no data going back long enough to judge sky/kaby lake longevity under these conditions. But you are right, that's a lot of voltage for Intels 14nm FF++. We used to estimate a service time of 10 years continuous operation under stock settings using a stock cooler for older chips. It is important to mention that we are talking about averages here, over a large sample size (quantitiy of CPU's used). There are two (kind of three) factors killing your CPU: 1. Heat 2. Voltage and actual operating speed (3. Electromigration caused by voltage en.wikipedia.org/wiki/Electromigration) Even if you OC your CPU without raising the stock voltage at all, it will die (slightly) faster. Even though there are no moving parts, the transistors are still being switched on and off using current (that's how the whole thing works after all...). When you decrease the intervall between the switching (aka increase the clock rate) by 10% you are effectively pushing through 10% more current *per time* through the transistors, thus increasing electromigration by 10%. Therefore the increase of wear on your CPU will be: Increase in clock rate + increase in voltage + additional heat. But it's not quite that simple, because both higher voltages and higher temps cause higher amounts of leakage current, which exponentially increases power consumption and wear, thus creating a negative feedback loop (higher clocks + voltage => higher temps => more current leakage => higher temps => and so on). It's obvious that there must me a serious amount of current leakage going on, since a 10% increase in clock speeds (from 4.5ish to 5.0 ish) more than doubles the power draw of the i5 8600k (from 60 way beyond 120). You can remove one factor of this equation (heat) which will realise a relative increase in lifespan, but you can't cheat physics. The other factor is, how thicc are the actual silicon parts of the cpu, how over engineered are they to withstand increased electromigration due to increased current leakage and heat? We simply don't know. I would expect it to last at least 3 to 4 years of continuous operation with decent cooling, but I will just remind you of the Northwood sudden death syndrome, way back in 2002 when suddenly overclocked P4's started dying because of the effects of electromigration. I completely agree with your assesment @kl, the 8700 is absolutely preferable over the 8600k. Less power draw, less heat, cooler included if you really want to use it, can be used on cheaper B and H boards, and Hyperthreading on top of that. It's a no brainer.

[@jort93z]

CPU's usually last at least 8 years even with a pretty stong overclock. They often last a lot longer. If they would die quickly, there wouldn't be a whole lot of 2600k's and 2500k's left but there are.

[@Itbankrock]

@Marcel Krebs Lol why so much hate? I DID NOT say that CPUs do not degrade at all, I just said they don't really do that much compared to a motherboard that it's paired with. Thanks for your very informative response tho :D

[@ettan85]

Argument towards going for a Ryzen vs i5 is if you are streaming. The extra cores/threads will give a smoother gaming and streaming experience on Ryzen!

[@killacamfoo]

I have a 5Ghz 8600K at 1.32v. 75*C on water. Easy to OC, will delid. Great chip. Kicks total ass in every game at 1440p with a GTX 1080.

[@sriunnikuttan]

Cpu has very little influence at your resolution btw.

[@killacamfoo]

this post has nothing to do with resolution other than stating what it is.

[@allieboy181]

I'm worried about cpu usage tho. It's seems that the cpu usage is higher or always at 100 percent on the 8600k

[@noceranunzio]

what's difference between 8400stock end 8400@2666? thks nice video anyway :)

[@MrSupraman15]

I bought 8700k on Black Friday also got z370 hero x main board this thing is a beast I can get 5.07stable@ 1.37 without delid this thing smashes games, csgo running with 1080ti at like 600fps also smashes 1440p or 4k whichever you like so 240hz users or even 144hz users this is the cpu u want period .

[@Najvalsa]

Anti comment warrior you don't need an 8700K for csgo, mate. Beast of a CPU though, you'll be set for awhile.

[@omarramsy6988]

headrushuk not exactly dumb as it will be very “future proof”

[@SKORPION11791]

He never said he wouldn't upgrade his monitor.

[@MrSupraman15]

I use cs as a bench because of uncapped frame rates I have a 4K monitor and a gsync 240 hz, also the core i5 don't historically last as long as the i7s due to threads and higher clocks so chill bro I'm just the guy saying "save your money and get somethin that will last you take it or leave it" now yea if your on a budget get what works but if you can save it will be worth it

[@MrSupraman15]

I mean for gaming look at the charts amd sucks compared to Intel I don't see how ppl recommend their shit so much save an extra 300 and buy into Intel and you will be good for years

[@Belgiumdoesnotkickas]

My 7700k is still in the top 3 with an average of 2-3 fps difference with the 8600k OC so that's good

[@AntonioDal.]

You should have turned off hyper threading with the i7 8700k for the game benchmarks. It seems the i7 8700k provides slightly more fps in many games if hyper threading is turned off.

[@AntilleanConfederation]

Competition between two manufactures = better quality product for us gamers. Let the competition never stop!!!! 😁😁 I get that some of u get mad when a new CPU comes 3 months after you purchased, but still. Better for us all.

[@chainedscythe2000]

I want to overclock my i5 8600k but my build theme is black and red. I am not able to get a Dark Rock Pro 3 but I can get the Noctua D15. Should I go for that despite it colour clashing quite significantly with EVERYTHING else?

[@n4mlss]

Grow up kid!

[@ThunderKat]

So in short the 8600k has issues with the lower cache and lack of HT, but this can be solve by OC he CPU into 5.0Ghz, also generate less heat and has a bit more room. In my country prices are crazy, is 400vs600U$$, that translate into 200U$$ I could invest in good and expensive heat-sink solution for the CPU.

[@folksyme]

What gpu were you using for this benchmarks ?

[@abheekgulati8551]

Thank you for the nice review as always Steve and GN. But if I can have a healthy disagreement here, I do not agree with you when you say a Coffee Lake i5 is good enough for gaming. Sure it is in your charts, and it's okay to just look at them and conclude, but this time, like many, you're being a little too objective here, and too much of anything isn't good! Here's my point: with Ryzen make 12 threads a sub $200 purchase, and core counts and threads increasing, game devs that start taking countless threads for granted will just become more common. Already look at the new Assassin's Creed, I'm sure if you check the CPU usage on a Coffee Lake i5 and an R5, one of them will be at 90%+ all the time, and we know which one. Also, I don't think $100 for twice the threads is too bad, think about it, most good Z370 boards today are around $200, and most people dropping that kind of money on a motherboard will hold on to it for a while. Sure, I'm an enthusiast and if a have $500 left I'll spend it on a new platform before I do on food, but that's just me and I'm sure most people will want to keep their systems for a while. In that case, they'll always be glad to have dropped the extra $100 on a truly future proof and quality product. You can't completely discount the future argument, not when we're talking just within the next 2 years! I'm certain that within that period, a 6 thread i5 will be a bottleneck, as even 12 thread i7s will be more affordable then. Cheers!

[@GamersNexus]

It's not all about threads, and we do not recommend based on "the future," which is nebulous and uncertain. We recommend based on now. I can't benchmark the future.

[@abheekgulati8551]

Gamers Nexus Fair enough, totally understand your stance too. Thank you for the response!

[@SMSmith]

Τhis channel should have a lot more subs.

[@ducktective7520]

I ended up getting an 8600k a while back for a price if 230 and when I got it I had no issues getting it to 4.7 without applying voltage even.

[@Seth22087]

Ryzen vs Coffee Lake is pretty much in what you want. Personally I think: - You should get Ryzen 5 or 7 if you are not high FPS gamer, Ryzen can easily deliver 100FPS or more. But it won't push FPS as hard as Coffee Lake will. But if you are fine with getting less FPS, you are getting more threads. Which I believe as we go into future, will give you longer lasting CPU. AMD makes things to last, not to get you to replace motherboard and CPU every few years. And Assassin's Creed Origins is good show of things to come, it can leverage CPU pretty well. My i5 6600 is pretty much getting maxed out with RX480. And now that cat is out of the box and games largely developed after Ryzen came out, will better leverage that. Since games coming out today still spent most of their development in Intel only era. Also of course Ryzen is better if you are doing production workload, especially R7. And in all cases, Ryzen usually is cheaper, especially cheaper than unlocked Coffee Lake. Also upgrading it might be easier since AM4 is here to stay for a while, so as far as I heard, Ryzen+ and Ryzen2 should both use it. Likely even further in future it will remain on AM24, but we don't know anything about motherboard compatibility yet. While on Intel side, Coffee lake requires new motherboard with same socket, just because Intel doesn't want old boards to be compatible, despite manufacturers saying it could be made compatible. And they already have new chipset planned which will allow 8 physical cores and it is not Z370, sucks to be you if you will be upgrading at that point, when 8 physical core i5 comes out. So yeah, Intel is already planning how to make most out of you by going in with smaller jumps. Which is kind of compelling enough reason for me to consider AMD more. - Now some melody for Intel fans. You should get Coffee Lake if you want uncompromised max FPS, if you absolutely find it unacceptable to be below 144FPS for you 144hz display. If you are already rocking overkill, like 1080 or 1080Ti for 1080p. Or if you want to fuel best framerate to your 240hz monitor. Intel is all about FPS. Yes you are not getting high core count, but then again, most games aren't there yet as well. And Intel is enjoying sweet fruits of all those years of Intel only optimizations for 4 or 8 threads and it truly shows in games with 6 core i5 and that is why not so much on 6 core 12 thread i7. Also Intel locked chips are at really compelling prices, especially once non-overclocking motherboards come out. Also Intel is great for people wanting to see those high frequencies due to really great overclocking ability to 5Ghz or more, depending on luck. Now to make things clear, personally I prefer Ryzen, simply due to budget oriented nature. You always get unlocked chip, you get great stock cooler with non-X CPUs, plus right now you have budget motherboards. I personally don't game on 144hz panel and if I would, I would likely invest in gSync or Freesync to have no stutter issues and live happily with Ryzen for a while. I just don't like Intels politics of having to change motherboard with every CPU, because they want me to. I also found Coffee Lake to be funny review business with whole multicore enhancement always on on some board and some signs that reviewers got better turbo chips with more budget locked CPUs, as well as not knowing what effects will non-overclocking boards and slower RAM speeds you might get on those have on performance. That is my stance on it. But this is how I view whole situation. Not to mention another motherboard change when Intel decides to come with 8 core chips.

[@adam346]

I can get my 8600k to 4.9ghz @ 1.28 volts.. stable. Also, nearly a year on i bought it for $305 CAD (235~USD)

[@BornaPrpic]

What does this say about 8700K? For gaming, the 8600K makes more sense (100+ USD going towards the GPU will always make a bigger impact).. For production work (most), Ryzen 7 1700 makes a lot more sense plus you get a decent cooler and a good cheap MBO - Asrock AB350M Pro4. (8C16T vs i5 6C6T no matter the clock difference). I kinda feel that the 8600K will be taking the market from their own 8700K. I also feel that when AMD APUs come out, they will be taking the market from their cheap 4C8T and lower CPUs. At the end of the day :) Been waiting almost 10 years to enjoy this level of competition.

[@watchornot3139]

Please what about the 8700 non k VS 8600k (70-80 Canadian more for 8700) novice builder never overclocked don’t know if it’s really needed even tho interests me. Don’t want aio want like 92 or 120 mm Zalman cpu fan... Gamers nexus/hardware unboxed etc doesn’t really touch 8700 on a z370. Help

[@joshpashia637]

How close to 100% utilization was the 8600k while testing?

[@KindOldRaven]

So... what if it's not 1440p very high/ultra we're after, but 1080p or 1440p 240fps/240hz? What would the game benchmarks look like if they were actually aimed at eliminating as much GPU bottleneck as possible and let the CPU go rampant? Competitive settings for instance (everything low except native resolution, and maybe 'high' textures)? There's literally no tests on that subject anywhere and its surprising to me. It even leads to misconceptions: I got told *not to buy a 240hz gsync* monitor (despite the 240 only being slightly more expensive than a decent 144hz panel) because my 6600k, 8gb ram, GTX980 wouldn't be able to push a consistent 144+fps in games like Fortnite, Overwatch and wouldn't be able to keep 240+ consistent in CSGO etc etc, which is obviously false.

[@ColtonSpears]

I really wish I wouldn't have went with the 1700x this year. Super good in benchmarks and decent when I run Blender but the tradeoffs are too much for me to not switch back to Intel.

[@rustcohle3803]

Compared to the i5 6400..... 8600k is a mind fuck. Fucking love it, had to get a liquid cooler though... wasn't that expensive. I'm just afraid of leaks. I seen more people with custom water cooling getting leaks more often though... maybe I'm safe with aftermarket stuff like corsair. I got the h80i v2

[@chetanbhasin1881]

Hello need help..my 8600k is 1.32v 4.8ghz avx stable.. and 5 GHz @ 1.34 v on MSI krait z370 non avx.. do you think I will be able to get to 5ghz avx stable on z390 aorus master to put an end to my OCD for 200 mhZ increase and 300$ poorer for the same.. thanks..😁

[@OnixStrav]

Now the r7 1700x processor is below 300$, sweet spot!

[@dongurudebro4579]

Great review as always but i would love to see a more common clock like 4,8GHz between stock and max. This would make it also a lot easier to tell the scaleing. Also it would be great if you could inklude Assassin’s Creed Origins in your Game Benchmark. I have to disagree a bit to your conclusion. I think Intel isn`t worth it, even for Gaming. At least for 95% of the audience. Cause to unleash the power of Intel`s K CPU`s, you need a 1080 ti a 240Hz monitor and Play those Games @ 1080p.

[@mapesdhs597]

It is amusing that all the tests which show a significant difference have frame rates that are high in an absolute sense anyway, and really only at 1080p. For the majority audience with 60Hz monitors, the extra performance is pointless, though I suppose it would provide some spare headroom for the future, and in the meantime if they lock in vsync then they'll save on power consumption. Perhaps there will be a more rapid shift to freesync/gsync in the months and years to come, but somehow I doubt it givent current relevant GPU and monitor pricing.

[@dongurudebro4579]

Well Freesync is pretty cheap and also those 570 & 580 are back to normal prices...

[@veruzzzz]

Tkank you so much for doing Blender benchmarks!!!

[@jaybajan]

if you had to buy one of these, which would you buy? 8600k - 8700k -8086K this is coming from a person who's running a i5-4690k

go with non bulshit i7 8700 for 10yrs of future packed performance. with 60 class gpu time to time

[@jondonnelly3]

If pairing with a nvidia 1080, The 8400 is all you need, if you pair with 1080ti, get the 8600k, if you stream get the 8700k. If you are broke get the Ryzen 1200 or 1400/cheap board and pair with a 1060 3gb. That's really all you need to know.

How long have we been waiting for CPUs with more than 4 cores and beyond the 4ghz range? Thanks to AMD, we are getting it finally

[@kallibaer32]

It's rather ridiculous from AMD advocates to hate on the Intel CPU's like that. I'm sure you'll be able to sell a 8600k for 60-70% of it's current price in 2 years from now. I'm pretty sure that won't be the case for current gen Ryzen processor's.

[@minepose98]

I mean AMD is sort of the only reason intel bumped up the cores in the cpus.

[@charliebrownau]

Gday Looks like the 1600 or 1600OC could be fine for 144hz / 144fps 1080p setup for those unwilling to spend the extra dosh for 165/200 hz screens

[@viktors_anfimovs]

ryzen and 144hz does not go together.

[@dongurudebro4579]

Yes Ryzen is just fine for most 144Hz titels and even for 90% of those 240Hz E-sport titels.

[@brianhennebeul1854]

If your talking about CS or less demanding games, maybe. Overwatch at 144hz, on a 1600, doesn't work to well in my experience, regardless of quality tweaks, and newer games at 144hz are just not possible at higher quality settings and resolutions, making it a sort of "why even bother" kind of affair in most cases. It's an ok chip, but for gaming, it's a little tough to recommend, and I'm 100% with Steve on Ryzen chips for pure, higher end gaming. If you REALLY want AMD for a mid-high end gaming rig, the vanilla R7 1700, with a good cooler, and as high as an overclock as you can obtain, is really the way to go. If not, then just go Intel.

[@dongurudebro4579]

@Brian Hennebeul I dont know what your talking about - you should get at least 250Hz on max Settings in Overwatch with a Ryzen CPU. Here s hort Video about that: kzbin.info/www/bejne/o6nIpJKQZad3bZI @Lofty Smalls No they have both the same clock once overclocked.

[@viktors_anfimovs]

You mean low preset? All those games sounds like were tested on low. Why wasn't dota2 tested? Because it really bad performing on ryzen, even on all low settings it bearably reaches 144hz let alone 240. Intel is really only option form me since i play dota 2 . On my 8700k its locked 144hz on max settings. plays and looks great.
