Yeah, they just pushed their CPUs to the max to make it looks more impressive on marketing just like how Intel pushed the i9 12900K to make it be slightly better than the R9 5950X at the cost of double the power consumption. It's quite cool that we can make then super efficient if we want to.

[@brandonbee9]

@AmpEdition If you tweak the chip to run a reasonable temp that doesn't require a high-end liquid cooler then the performance loss puts in barely above last gen(plenty of videos that have undervolted with tests) . Add in the total cost of upgrading to this platform and this is a pointless release. Last gen barely loses performance and costs half as much.

Yo phil, gonna piggyback on your comment. Another large problem that I think wasn't touch upon is that you can't possibly measure temperature at every spot of the die. It's just not viable, you can I guess run extensive tests on the silicon and have multiple temperature sensors per core and send back the hotspot only to avoid damaging the die.

True, it is the same with the intel 12th gen, at least for K and KF SKUs. If I let my 12600K boost to 180W it will score around 18k on cinebench R23, working 15min on UV I got the same 18k points but at 145W, which is already quite impressive. I took it further, always with a -90mV UV I locked the power to 95W and I still got an insane 16.9K on R23, at 65W it goes down to 14k and still touches 12k points at 45W. This seems to be true also for the new gens. Simply awesome

[@mastroitek]

@@vaggeliskosiatzis5487 I think the 12600k should boost at 150w stock but depending on the motherboard you can get different profiles, in my case if I remove the power limiter it will suck-up 180W and stay there (->18k). Fully stock the 12600k should score around 17k or something more, so in a sense I managed to squeeze another 700-1k points but reducing power consumption. With that said 145W + UV (->18k) still puts the CPU way out of the efficiency curve since with 95W it can perform roughly on par to stock (->17k). About binning I'm not sure if there is any difference between i5 and i7, but mobo and especially operating temps are important, I like a silent PC so even with the 145W profile I was targeting 85-90C which is not great for efficiency... It is probable that with the fans at 60-70% (instead of 20-25%) my temps would have been around 65C giving a bump in efficiency. And the last important variable is the silicon lottery

People are saying that because AMD is stating that. It seems to be about 100 watts difference, which could be significant, it depends upon how often you hit max power on your rig, which honestly is not something I ever check for me so I really have no idea. But lets say you do 10 hours a day on average at max power, that's 1kWh difference per day (10hrs x 100watts), here's a situation that's probably well above the average person so now it's just a matter of multiplying by your electricity rate to find out the daily cost and 365 for the yearly cost, for me in California it's nearly 40c/kWh so that translates to just under $150/yeah which would be a pretty good chunk of change however how realistic is 10 hours a day on average? well everyone needs to answer that question for themselves, but if you go to 2hrs/day on average then $30/year (for me) which is less of a bother IMO.

@@JocaGod this is because the CPU doesn't run hot because it's using a lot of power, but actually because the CCD is very small and doesn't have the sufficient surface area to dissipate heat.

You don’t think about this stuff and that your gonna save money its damn CPU a gaming machine. If you want to d.ride the efficiency go buy a laptop and make it a desktop system.

Ryzen Master has improved since you made this video. I used its automatic Core Optimizer tweak then set up two "Profiles," one for performance and one for economy. Each profile has its own peak voltage and peak clock speed. It's been months since I've used anything but the economy profile. "Economy" gets me to between 2% and 7% of peak performance but use 25 to 35% less power. I'm a very cappy hamper!

[@rodrirm]

Have you tested, or are you considering testing the ECO modes to compare to this undervolts? I would love to see what happend on those modes.

[@MagicBrownMan]

This is my question too. I prefer the way it is; most CPUs/GPU are running at max and under-volting is the new overclocking. This way out of the box you get the best you can but if you care about efficiency, you can hit that as well. Also, it means these parts are designed to run under the higher power/heat state extending the life of the product if you care about efficiency. Overall, it's a win win.

Thank you alot for this video! I'm waiting for my full AMD PC build with 7900x and my heart fell when i saw 170W TDP (after i already paid for it) and the temp's with these cpu's. I am 100% undervolting. Again, thank you a shit load for this video!

[@phoenixbird7579]

As I said on another channel, AMD just overclocked the new CPU and fixed it as default, soon we will have Under-Clocking as a feature in CPUs as manufacturers will ship them with maximum frequencies. 95 degrees all time when there is a load as per AMD is a joke. I believe Intel is doing the same. As you said perfectly, I also would prefer a 4.8 GHz default with low temps. Thanks for this great video, its kinda different from most who are telling me how fast is the CPU. it would be a great comparison once intel 13th gen is out based on temp or watt and not on maximum frequency/FPS at any cost, most people don't feel the difference in their power bills, however as per your test above 200 watts reduction would make a big difference especially if you are like me keeping your PC on 24/7 and use it for hours every day... great work keep it up.

I have now Ryzen 5950x worked on custom cooling system with 2 360mm huge radiators, And I undervolted the CPU to be able to use it in the x570 chipset! , I was thinking to Upgrade to 7950x but since the temperature issues still there I will not buy it and I will be waiting for the new intel CPU coming .

Curve optimizer and then a heat and power cap seems to be the best way to go based on Optimum Techs video.

Bravo. This is the 7950 review I was waiting for! And very glad to see the undervolting difference under 3% for both GPU and CPU. I will definitely be following this route to avoid turning my home office into an oven.

[@nmathew01]

Yes, that was.... surprising. I'm wondering if it holds up over more games. It's also odd that I'm seeing some improvement on the 1% timings in this video and some ECO miss testing videos I've watched. Something strange is going on there. Maybe constraining the average power gives headroom for a single core to spike high when needed?

[@lorancortez9795]

I tried your ryzen master settings on my corona render. Undervolted & underclocked Vs. Stock, result was 30c(65c vs. 95c) cooler and 50% more power efficient with only 18 seconds render difference. Thanks.

[@snowhawk4049]

If you ask me AMD was afraid that the 7950x couldn't outperform the 5800x3d in gaming and therefore cranked up the 7950x.

[@samiraperi467]

And 5800X3D still beats the 7950X in some benchmarks. Zen 4 with 3D cache should be insane when it comes.

[@forog1]

I did the same with just my 5950x. I shaved off 200mhz on its single core and undervolted it's all core. It led to running cooler in games while only dropping 5% at most fps and it's all core got a bump up in speed from 4.0ghz to 4.2ghz and scores a bit higher as a result with its all core. PBO is still disabled this is just a simple undervolt and couldn't be happier with my quieter system

[@zeroconduction]

This combined with der8auer's findings that the IHS is really inefficient could be pretty interesting. Imagine undervolting plus delidding.

[@erhanozaydin853]

A bit redundant practically but I'd wanna see those numbers too.

[@dwinterx]

Very interesting thanks man. Just ordered a 7900x, so I'll be definitely undervolting a bit. A huge difference!

[@tirve]

hello sir, just bought the 7900x. Did you undervolt it? If so, how and which settings you used? I would really appreciate it if you tell me :)

[@adventtrooper]

Thank you for the insight into the new series. With the way energy prices are going, it's far more useful to see how the PCs can be run efficiently with off-the-shelf kit than ever more elaborate and makeshift cooling systems to gain a few benchmark ranks.

[@thilinalakmal]

Did the same on my 5900X when I got it almost 2 years ago. Dropped the temp from 90C to 50C with just an Gigabyte Aorus air cooler.

[@TrevorLentz]

I'm extremely curious of what the non-X 7xxx series CPUs temperatures will be out of box with a stock cooler. It seems that AMD is pushing these X variants out to content creators with the hype train in mind, in efforts to crush all existing benchmarks. If they keep efficiency similar to the under-volt shown here in their non-x skus, it looks quite promising.

[@MrDante134]

I'm really glad I found your video. When I put in my 7700x and it kept jumping around in temps at idle I thought my cooler wasn't working properly because I'm using my NZXT Kraken z63 from my last build. I used your settings and the 7700x never went passed 50 degrees Celsius at maybe 1-3 fps loss. Incredibly helpful and more people should definitely be talking about this.

[@lukehodgkinson4261]

Just bought a 7700x for my son does Ryzen master hold the values when rebooting the system? If not how can you save it to hold when rebooting? what values did you use. Building the PC in the next few days cheers Luke Hodgkinson

[@TimLongson]

The Ryzen 9 7950X3D cache is rumoured to not be release until CES 2023 (Jan 5th-8th 2023). Having seen the HUGE boost in performance that the 3D cache gave to the 5800X3D, to the point where that last generation chip holds its own against the just released 7950X and the not yet released intel 13th gen flag ship, there is no way I would get a CPU before the 3D cache version, so I am praying the Ryzen 9 7950X3D is released sooner, just after intel 13th gen, so they crush it, and I don't have to wait even more months before building a brand new from scratch rig. Fingers crossed AMD have the sense to release the Ryzen 9 7950X3D straight after intel 13th gen so that AMD can corner the market before the Christmas purchasing rush!

[@predater5017]

glad someone else has noticed this, youre the first tech channel pointing this out. they are all pusshing clocks to the max without care for power usage.

[@Alupl]

I think a better way is to use curve optimizer with negative all cores 15 (or more/per core if you want) + setting target PBO temp to 80 or 70 celsius. That way it stays low in idle and boosts high in single core but stays cooler in all cores workloads :)

[@K41Z3RR]

Like that, yes. I limited the temperature to 80 and set the negative curve to 20. That's 5.0 ghz tdp 150w with the Arctic LF ii 280 running at 80% power (180ppt, 140tdc, 200edc). While through the BIOS - Ryzen Master cannot start with the computer, it's annoying. A little disappointed - expected more frequency like 5.2 or smtn. I'm new to this, maybe something else will be improved later. upd: 20 is unstable, 10-15 is ok)) I don't know how some people put 30, they must be very lucky with their rocks.

[@thumbwarriordx]

It's such an issue how they handle temp now just because it ruins the entire fan curve paradigm we've been using forever. Unironically Ryzen needs the Turbo button back. Either to switch your PBO profile on the fly or swap between your nice friendly 1700 RPM fan curves to you ear-shattering 3200RPM fan curves.

[@K41Z3RR]

@@thumbwarriordx I literally have a couple of fan control profiles in Gigbyte Control Center)) One for everyday work, when the fans run at 70-75% in case of limited CPU heating to 85 degrees, and the other - "no one is at home", when the fans run at 100 %. The two profiles provide different performance, although the difference is small. It's funny. And yes, it's pretty weird. But I can't say that it gives me any problems.

[@tcathunder]

Well done... My 7950 is set at 46.00 mhz .625 volt temp 55c. Runs like a dream..

[@modernmanueee_]

For whoever is seeing this video 9 months later: these chips are designed to get at 95 degrees no matter what when talking about boost frequencies. Of course, if you take away their boost capabilities, you take down the temperature. Do not apply excessive undervolting if you actually need it

[@atorbtech]

I use a ryzen 9 7950x. With 1.04Volts and at 4800Mhz the CPU temp is below 48 degrees when idle. It goes to around 55 degrees under light load like browsing. It uses around 45 watts when idle. Almost 100 watts lower.

[@juhopeltonen1531]

With curve optimizer you can get undervolt with negative clock curve set ! That allows your CPU's best cores to boost higher in single thread work loads. Would it be better?

[@Fezzy976]

Damn! Now that is what I call an undervolt! You just dropped temps by 40C!!??? Holy crap!! I had some similar results with my 7900XTX dropping voltages down to 1120mV from 1150mV and locking min and max clocks to 2400/2500 respectively and VRAM to 2714MHz (which gives a locked 2700MHz). This dropped temps from 107C on the junction to around 75-80C max!

[@sbrader97]

Someone needs to test lapping the ihs since der8auer showed a 20c reduction at a fixed oc by using direct die thats some performance left on the table because of such a bad ihs

People did this with the Ryzen 3000 series as well, but the issue is that the single core performance gets the largest hit. 15% in Cinebench.

[@mamdouh-Tawadros]

Thank you for a great video. But to me the obvious advantage of 7900X over 5900X is about 10-15% improvement, while doubling the price.

[@TechnoBabble]

Doubling the price?

[@cosminmilitaru9920]

This is actually absolutely real useful information, thanks! Not everyone lives in Sweden or Canada to enjoy the heat output of a 230W CPU consumed - and would gladly give up 5% performance / 100W of the consumption to have reasonable heat output of 130W consumed as this can also be cooled easily with all decent air-coolers. Also the reason why I undervolt GPUs, when your computer takes 600 W from the wall you already need an 1000w consuming AC to counter that and it's stupid; for 350W not so much. Besides it's nice to have lower temps, longer fan lifespan, lower noise, and avoiding liquid hazards, I mean, liquid cooling. I am aware not all CPUs are equal so then BIOSes cannot be set for Undervolting settings that would work stable on all CPUs, but this is like the default BIOS profile is for Overvolting. Haven't seen anyone test Eco Mode yet though, but I'm positive it does not compare to manual overclocking and undervolting that I usually do on CPUs and GPUs.

[@tsabrack]

It would be interesting to add another axis, i.e the resolution. If the performance loss is on the same order of magnitude no matter the resolution ... then it'd be silly not to undervolt like you suggest

[@mathewbriggs6667]

Thank God your the best reviewer I gess because all the other's just roll on there back and go well it's designed to over heat

[@wildfire9887]

Undervolted my 7700x, pretty much identical to your settings. Saw similar drops in my performance and went from 95.5C to 64.1C and from 138.34w to 73.40w peaks while running Cinebench!!! This my first time undervolting, any advice to optimize my settings or is it really as simple as adjusting your voltage and clock speed to the desired "sweet spot"? For those who care, these are my Cinebench scores for the 7700x: 7700x Cinebench Multi Core (Stock): 18850 pts 7700x Cinebench Single Core Core (Stock): 1976 pts 7700x Cinebench Multi Core (Undervolt): 18257 pts 7700x Cinebench Single Core (Undervolt): 1720 pts

[@K41Z3RR]

65w is half the performance. I've seen in tests. 160-180 is optimal numbers.

[@guynamedstella]

Felt like chiming in here. I was being annoyed that my CPU would go above 80C when simply watching youtube - more specifically whenever I would skip in parts of a video, the temps would shoot up for no reason. After undervolting and lowering the core clocks to 4800 MHz the performance is night and day! Now my CPU temps stay at around 40-50C instead of touching throttling temps. Thank you for this!

[@esc952]

DeBauer cooled it down 20 deg C by removing the IHS and cooling direct to the chip/chiplets. My guess is that you shaving 40 degrees already based on power consumption, removing the IHS would only shave another 10-12 degress. However, that would open up some interesting possibilities to bump your core reduction up to 4.9 or 5 while still maybe cooling it down to 50c. You should talk to him and maybe do a tuning collab.

[@overlord580]

Thanks man. There's no way i would put fans on max rpm. Silence is golden.

[@shiba7651]

Have you tried eco mode? Should be doing about the same but just by turning this setting on

[@mapwheel00]

Lol this. There is literally a button in Ryzen Master to solve this if you care about power consumption and heat. Also, confirming a stable undervolt on a 16 core processor takes weeks of daily, routine testing to ensure stability at all points on the power curve. It cannot be done in a 48 hour release window.

[@Tatertot01]

Great video! You've changed my mind and I'm sure many others on the 7000 series. When I heard that 95c was the "new normal" I was like....nope I'm never buying this. But you've made it look attractive now. Much thx!

[@NarekAvetisyan]

Also for whoever is concerned with loosing single core performance with this method... Asus has this Dynamic OC switcher on some of their motherboards. Where you can set the CPU to run with PBO under 35 amps for maximum single core performance. And above 35 amps to switch to manual OC mode for all core performance, wherever you want to set it up for efficiency all core or maximum performance all core. Which is very convenient.

[@teddyoflove5897]

Nice to see this is an option. I am running 5900x curve optimizer undervolt -30 and my rtx3080 undervolted to run 1890mhz at 0.86v. Only got good results from what I experienced with undervolts. They push these products to obsolute maximum just to best their contender. But forget to give us an option to not waste tons of power and heat while sacrificing few %perf. For long usage sesions like gaming undervolt is the best way when dealing with flagship parts.

[@constantin58]

I found the optimal settings for my 7950x were -250mhz, -1.3V offset on CPU , 1.06V SOC(infiniti fabric) . Cpu idles at ~30W, max 185W, casual workloads and gaming 65C, (90C on CInebench) All the cores hit 5.5Ghz randomly. In Cinebench R23 half of the cores are 5.17ghz/other half 5.07ghz with a score of 1967/38000+
