They've been slowly taking away PCIe lanes and slots on consumer products, and they sequester remaining lanes in m.2 or add excessive 1GB NICs to tie them up.

Honestly other than guaranteed ECC UDIMM support, i'm not very interested in 4004 The platform is great, that is an easy way to get guaranteed support for people who dont want to research what consumer boards work for their use case.(edit, i'll probably pick up a board for my 7950x to replace my x670E PG lightning) But for me to care about 4004 processors it needs to be more than just consumer cores in an enterprise motherboard. I'll give some examples of what i'd like to see from Epyc 4004 or 4005 There are ~370 extra pins over AM4 sure some of those are going to be for power, but most likely are for 'future expansion' so maybe these 4004 could have a different IO die option, and enterprise motherboards could add a 3rd channel of RAM These are being called Epyc, why not Zen4C for up to 32 cores. If they dont want to open pandora's box like Intel did with the first gen i7 LGA 1366 and subsequent people upset by the 2700k not having 3 channel, then maybe add another 8-16 PCIe lanes from those 370 pins. honestly i was surprised the 7940HX/8940HX/8700G dont support tripple channel, the iGPU is starved for bandwidth even at 8000 in 1:1 the 8700G seems starved, with notable improvements just going from DOCP 8000 to an OC of 8400

Next Gen, we might be able to see a Zen5c x 2CCD (32 cores) or a Zen5+Zen5c (24 cores) on AM5 socket.

I guess the justification must be related to the cost of software vs hardware. I would prefer a product the complete opposite. Use a max package size Epyc, load it up with 24 or 32 core cpu, W series graphics, lots of cache, maybe even ram, and reduced pcie lane count, similar to TR. Now it is a larger area, easy to cool package, blender and video editing monster. System memory using a couple of M.2 and now no goofing around with a separate graphics card.

I'd love to build an epyc home supercomputer but these nodes are too crippled with pcie/memory bandwidth don't forget need some infiniband or something for each node eating at least 8 probably 16 lanes too just not enough :(

Like damn I still love the 7443P $1000 for 24 cores and 128 lanes of pcie4 is a sweet spot I bet another year or so they'll be flooding ebay :D :D

You didn't mention pcie Lanes. Do these have the same as their desktop counterpart? That seems like a fail if true

28 pcie lanes shown in the video

Would the 16 core Epyc 4665P draw 170w if given a 12 core 4464P (65w) workload on Linux? The mixed core thing that Intel has been doing says otherwise but I thought the fundamental result was race to finish so you can power down the core.

No it would not. Two things though. As you go the V/F curve, things get less efficient so usually same core lower wattage does well. Second, there are still a lot of 120W/U racks out there so a 65W TDP CPU fits but a 170W can incur overages.

Asrock DeskMeet X600 supported 4464p ?

I want a cheap Ryzen x900g which will fit on a EPYC motherboard , I want the extra lines , 20 lines is very limiting for a home lab set up.

To be fair to Intel, recent desktop Core CPUs have server features. Intel ARK lists the 14900K as ECC-capable, the processor gets official RHEL certification, and boards like the X13SAE are certified for popular Linux distros. If your OS is happy with a P+E core processor, I don't see any reason to get an Xeon E2400 over a 13th Gen Core. AMD is launching a full lineup because unlike Intel, their desktop lineup is missing several features (ECC certification and SEV).

Im still amazed at the idea of 5.7ghz in a server chassis.

4:50: so basically because of officially supported ECC.

Yes. Also things like 25GbE NICs are not often validated against Ryzen CPUs

We have reviewed a few B650 server boards on the STH main site IIRC.

Is there Siena review somewhere? Did I miss it? That is great however for really "cheap" servers that don't use old parts. So yes, very good move AMD.

STH and Phoenix "reviewed" the launch - to be fair with Siena it was easy to predict what the performance and power would look like. There is some testing in STH's motherboard reviews like this one: www.servethehome.com/giga-computing-gigabyte-me33-ar0-amd-epyc-8004-motherboard-review/2/

Fantastic.

So they did end up making a zen 4 based ryzen 3 but just in disguise as an epyc chip

So, is the primary difference just the qualification vs a Ryzen processor? I had to watch this in pieces, so maybe you covered it.

Yup it is just the extra qualifications.

@ApplePotato I guess that makes it more official than a server board running a Ryzen chip. I run an AM4 asrock rack server...but that it at my house.

What do you mean new It's a rebranded ryzen 7000 supported by their server FAE group with some additional software validation testing. It's ryzen 7000, it's been around a while.

epyc uses the same CPU chiplets anyway so Ryzens have always been the same thing

Do these chips behave identical to their Ryzen counterparts for gaming?

@ServeTheHomeVideo

Ай бұрын

Very similar except usually server board have tighter PL controls to keep power in check. Think of these as Ryzen if you put more constraints on power. The ASRock Rack server has a GPU slot for a reason :)

@noname-gp6hk

Ай бұрын

Have you tested that or are you just assuming 'because it is server branded now'? I'm not aware of this having any different power control than the ryzen 7000 parts. They even use the same AGESA code. The BIOS updates pretty much just add text strings to identify the new CPU names. These should perform identical to their ryzen 7000 counterparts.

Oof only 2 channels of DD5 not saying memory bandwidth these days is everything but in the long run it's everything

This would be a GREAT gaming system. It's rackmountable, you can drop in either the Ryzen or the EPYC 4004 series into the motherboard, and it can fit a 3-slot wide GPU (where many rackmount chassis can't, or you have to buy custom 3U rackmount chassis). Win-win-win. Power consumption is crazy high, but I bet so long as you keep the temps in check for the CPU and the GPU, you can probably get away with a Noctua fan swap.

@@erkinalp I dunno though. My Ryzen 5950X has full performance well after EOL, so I don't know if the EPYC is really any better binned than the Ryzen desktop counterpart.

Advantek and Lenovo predate Ryzen ECC commercial work group and industrial server and workstation so around since Vermeer. Ryzen parts were being used by all the typical Asia Pacific ODMs for small office work group and for some time I get extension of 'Pro' as 'into' commercial / industrial . . . The fact is there are a ton of Raphael at run end and yes Epyc 4000 made sense. Raptor E channel available gained + 258% in the last month so this should be an easy virtual desktop and workstation group server race for AMD to win relying on a desktop part. mb

I wonder if it's possible to bifurcate the PCIe lanes. I have a couple of AI workloads that are (somehow) not as PCIe bandwidth bottlenecked as you would expect, so I could possibly get away with x4 connections on a huge number of GPUs, and this server would fit really well with my power consumption issues.

This type of servers will not run VMWare, due to the obvious reasons - they are for low-end markets, instead of VMWare portfolio, where recently is focused only for enterprise one. Porxmox, XCP-NG, Nutanix - these will be the focus here :)
