I wish motherboard manufacturers took this opportunity to spend big on PCIe switches, to turn those 28 PCIe 5.0 lanes from the CPU into 56 PCIe 4.0 lanes. Yeah, PCIe switches are expensive as all heck, especially 5.0 ones, but PCIe lanes are exactly what I need in a server context

[@TheChadXperience909]

Thank you, wendel

[@jimspc07]

You brought up something that I think is overlooked but sorely needed. A change in PCIE layout capacities on ATX and MATX motherboards. Not long ago the first PCIE was 16 lane electrical and 16 lane positions. A second PCIE was 8 lane electrical and 16 lane positions. A third PCIE and even a fourth, was single lane only or maybe 4 lane on some boards. Today we have 16 lanes on PCIE1 and maybe a 4 lane on PCIE2 if fitted and maybe a single lane PCIE as well. I'm with you, I would rather see PCIE 1 and 2 both being 8 lane and 16 lane positions, with additional single lane(s) as well. The supply of 16 lanes to PCIE 1 is a waste for most PC users. Firstly they don't game or so infrequently they don't need a 16 lane GPU, secondly, not all GPUs are even 16 lanes. There are lots of PCIE plugin boards that are available and in use today that need to be plugged into the 16 lane slot even when they are 8 lanes, with some boards 4 lanes. Thus requiring the GPU to go or be relocated to a 4 lane chipset slot. Changing the 16 lane slot to 4x4x4x4 or 8X8 or whatever does not help when the unused lanes cannot be reallocated as there are no electrical connections to be had on the board. And USB 3.2 gen2 or USB4 cannot be used as an alternative as many MBs only have USB2 or 3.2 gen1. I don't think that motherboard makers are actually supporting the market well. Many boards are simply clones of another with a different name and "go faster" paint stripes added or removed. They are all obsessed with gaming. Yes, its big but many are casual gamers who use a pc for other purposes as well or exclusively. Many of these users have moved to big brand prebuilt basic boxes or laptops as they can no longer build a desktop PC that works for them at a reasonable price. Also I am not surprised that Asrock came up with a beta bios, I have put them as the best support company for years and have had special beta bios private download links from them in the past in response to email enquiries.

[@scooperdive]

AM5 Epyc looks very interested, i'd be interested to see how this progresses and if they keep going with it.

[@metaleggman18]

Ah man, I was really hoping this would mean AM5 but with a few extra PCIe lanes. Even like 32 or 36 would be nice, instead of 28. I guess desktop CPUs are just so physically constrained at this point that architecturally it's not possible. The only reason I say this is because my first computer was during the heyday of SLi and Crossfire, and I think my EVGA motherboards all supported three-way SLi (though I never used it since I was using hand-me down monitors for the longest time on a kickass gaming rig; I didn't know any better thankfully haha. Too bad it was a hand-me down LCD Dell monitor and not our old Sony Trinitron. If only I had the sense to hook that bad boy up). So, because of that, all the high-end enthusiast boards had at least like four x16 PCIe slots. They weren't necessarily electrically x16 (either physically or they'd switch to x8 or x4 depending on the use case), but what that meant was I never had trouble with expansion. Now with my x570 board, because of the limitations of modern boards, you really can't get PCIe NVME expansion cards on there unless you want to switch your GPU to the second slot, which depending on the BIOS, might be hinky to begin with. It's really sad since you have these wild Epyc and Threadripper processors with 128 PCIe lanes, but then we're stuck with a dinky 28 lanes on AM5. Though Intel has been even more anemic than AMD's AM4 and AM5 platforms, so really, I should just be counting my lucky stars, I guess.

[@Hugh_I]

Theoretically it is possible with desktop CPUs. I don't think an IO die with a couple more lanes would be that much bigger to fit in the package. But the AM5 socket is not designed for it, you'd also need the extra pins on the socket to route those lanes out. What is possible though is to use PCIe switches (or the chipsets) to split the existing lanes into slower, but more lanes. Doesn't increase the total bandwidth, but you could say take the 16 gen5 lanes that go to the GPU slot and make 32 gen4 lanes with full bandwidth out of them. I'd love to have an AM5 board like that, don't need fast lanes, I'll take gen3 lanes too. But esp. for a home server type scenario, a board with a good number of PCIe slots would be nice.

[@aminy23]

My B550-XE STRIX has the graphics card in the first slot, and I use the included expansion card for additional NVMe SSDs in the second X16 slot. Keep in mind it's not easy to utilize the bandwidth of multiple NVMe SSDs unless you're doing something like a RAID. Their bandwidth requires multiple threads and queues.

[@Hugh_I]

Should be possible to run the existing parts at 35W, if those BIOS allow you to change precision boost limits like desktop boards do. However even official 35W variants of the same parts wouldn't have much lower power draw when idling than the higher TDP versions. They're just limited in how much power they can draw when boosting clocks under load. That is, unless AMD releases Epyc variants of the APUs. Those generally have notably lower idle power draw than the chiplet based Ryzens.

[@larsjrgensen5975]

A 65W part would just finish quicker and then go to sleep for longer time then the 35W part. The power needed to run a 65W or a 35W system for a year is close to each other, if the work feed to them both is the same. You might want to go with a 7840u / 8840u (pro) if you can live with the lower lanes count and PCI 4. Less idle power draw and more work per watt.

@@TheChadXperience909 I generally don't use consumer motherboards for my servers. Not sure why you think I need to rebuild my workstation which is fine for my needs at the moment.

[@Fractal_32]

I want to run one of these as a file server for my house and to try out remote management. Now only if ASRock Rack could make a board that was half as expensive so it would make sense to run the 6 core in a server board. (I do not need the extra performance and of course cost of the higher end chips.)

[@ivanstefancic8938]

The x870e motherboard's are "dual die solutions" I interpreted that as dual socket 😅 Fingers crossed 🤞

[@pitz_nous]

tbh, considering the price of ram my old 1600x is not moving for now, it is doing it just fine, support pck bifurcation on a 470x mobo, and support 4 stick of ram better

[@thedevminer]

not worth the lack of PCIe lanes.

[@Terran.Marine.2]

Is there a chart somewhere that shows which RAM speeds and types are supported by which motherboards and CPUs? I think I saw 8,000 MT/s registered ECC RAM for sale, although I think it was $1,000 when i last looked.

[@quanlethienminh6002]

I really wish they release a 5950x3D version with both CCD having 3D cache, it has the level of MT that I need and for gaming task, it will last me a while!

[@GewelReal]

Time to retire E3 Xeons???

[@ryanmalone2681]

I’ve often wondered why there were plenty of dual socket Intel or AMD consumer socket motherboards. I would definitely buy one or two over the Xeons I have in all my servers.

[@WoTpro]

man i gotta say i love Wendel!!!!

[@JoeBleaux69]

1:50 is there no way to use a external secondary case for pci components maybe?

[@raddinox2707]

Would love to know more about the R9 7900 motherboard and ECC combo

[@GoPlayMLP]

great video, as always! Really stoked to see where this is going for AMD.

[@YolandaPlayne]

This would be really nice for onprem AI as well.

[@jefferyG499]

What is the use case for 3D V-Cache outside of gaming? There has been tons of testing going back to 5800X3D that all concluded that it was slower than the 5800X due to the slightly lower clock speed. When equalized for clock speed, the cache provided no performance gain from 3D V-Cache. AMD's own website on the matter says "GAMING", "GAMING", "GAMING for the desktop and the mention of it on servers is "With the addition of AMD 3D V-Cache technology, EPYC processors reach new heights to become the world’s highest performing x86 server processors for technical computing."2 The 2 says that it's the fastest with SPEC... without any indicator that the 3D V-Cache is what enables that.

[@Cynyr]

there are other workloads out there that really benefit from more cache. CFD/FEA both come to mind.

[@LisaSamaritan]

It helps a little in a lot of situations and a lot in some. But an average of 12% is quite good. If you can fitt all your code in the cache, you will get a lot higher performance. From Phoronix article "The Performance Impact Of Genoa-X's 3D V-Cache With The AMD EPYC 9684X" (The results are after testing 130+ different benchmarks. We are not talking games, but actual applications and workloads that you would use on servers and workstations.). "Across that wide range of diverse Linux workloads, the EPYC 9684X was on average boosted by around 12% when utilizing the 3D V-Cache."

[@ElijahSamsonWiltonChen]

im glad i held off getting a w680/14900k last month lmao

[@gertjanvandermeij4265]

*IT can be done, but I think you lose a lot of lanes !*

[@rh3r0]

amd should just do the work for Plex to get hardware transcoding on their igpu's. only reason I havent gone full AMD

[@alberte6109]

Wow seems like I can reasonably gift my brother an Epyc powered computer

[@NatesRandomVideo]

Wendell has a CPU storage box… of course. Ha. 😂

[@SpecialKLSX]

Meanwhile GN Steve has a... Shelf. Of them. Then again he tests nearly every SKU, eventually. And has been in the game since Pentium 3?

[@cute7752]

Now I want that dual Hygon System to play around too.

[@gdamjan]

It would've been nice if they supported SEV-SNP on the EPYC 4004 os we can play with that at home

[@blindsniper35]

So this thing is the competitor to all of those Intel chips that the data centers were having problems with. If the price is right that could be very challenging for Intel.

[@aminy23]

Intel will have new chips on TSMC 3nm this year which will be a game changer. They will have 12P Core Bartlett Lake on LGA1700 around January which should hopefully address all the issues of the 13th/14th gen B0 die.

[@Krithalith]

I wish they would release 24 and 32 core for am5. Don't think that's happening any time soon though. I am in a stupid niche of wanting more multicore but not caring about memory bandwidth and other extra features. My only options are 7950X (which I have now), or threadripper / epyc which has way worse price / performance.

[@jesh879]

zen 6 will likely see double core count

[@Krithalith]

@@jesh879 Yeah, I'm probably getting a 9950X in the meantime. I just can't stomach spending 3500+ on a completely new Threadripper system just to have double the corecount (using 7970x as an example) 🥲

[@nikolaforzane2285]

How is the 7950x treating you? I'm a hair-trigger from buying it, but 95degCelsius scares me.

[@Krithalith]

@@nikolaforzane2285 I'm very happy with it. Yes it will go to 95C on an all-core workload, but that's what it's designed to do. I've run it for hundreds of hours like that with no issue. If it really bothers you you can always just set a slightly lower PPT limit in the Ryzen Master software. It's a fantastic chip for multi-threaded workloads.

[@arnebaekhansen]

Supermicro SAE13-MF is your pick for the combo of IO on your wish list... plus it's awesome because it's SuperO

[@ky5666]

That's what I thought at well. Wendell doesn't seem to cover much Supermicro gear for some reason? For some annoying reason it omits overclocking support. I like server/workstation motherboard in my builds as I keep them for a long time.

[@arnebaekhansen]

@@ky5666 conspicuous in it's absence. Wendell does have an agreement with Asrock, so perhaps that's the issue!

[@madwolf-us4sc]

What I do not understand is why they do not reduce the TDP for the 16 core parts, many of the 1U or dense server config does not support more than 105w TDP, only a 1 SKU at 170w is crazy especially for datacenter use.

[@wendelltron]

dont forget about ecomode, works stunningly well for the 1u usecase

[@chionyenkwu2253]

Great vid; One lil issue though==> asrock's website lists ethernet ports on 650D4U as follows; 2 RJ45 (1GbE) by intel i210 NOT dual 10Gb ?

[@axescar]

Hope to see 4005 Epyc on Zen5c cores with something like 32 cores

[@Ryet9]

**Crys in 3.3Ghz boost clock**

[@ShadowFox_2090]

Hi Wendell; this is a great video but I would be remiss if I didn't point out that I was bit confused you mention 7000 series EPYC parts like the 7343 and 7543 in the video; you also on the graph have a 7343P listed; the 7543 is a 32 core Milan (Zen 3) based chip and the 7343P does not exist I assume you are talking about the 7343 non P but this is again a Zen 3 based 16 core part. You also mention swapping in a 7000 series EPYC part later in the video. I'm not sure exactly what you mean and what you are trying to compare here??? Maybe you meant 4004 series EPYC and I got confused...

[@JJFX-]

I honestly don't get it, what's so compelling about relabeled, locked Ryzen parts that lack most the features that real EPYC has? There's no additional lanes or notable security features that I can see. ECC support and remote management just comes down to the motherboard. This feels like a way for AMD to sell off a bunch of old Zen4 dies at a premium before Zen5 releases and then do the same thing again next year.

[@marcelovidal4023]

amd uses dual chipset... why not gives a dual motherboard cpu :S

[@clementajaegbu6660]

Wonder how these compare with the 8 n 16 core chips in minisforum 590i and790i - 7745hx and 7945hx 😎😎

[@ericthedesigner]

We need more PCIe lanes!!!!! ugh. Am I the only one that runs out of lanes with the 16 core ryzen? I don't want to switch to threadripper just to run more m.2's and video cards.
