AMD Readies Socket AM5 EPYC 4004 Series Server Processors

[btarunr]

AMD is readying a new line of EPYC branded server processors in the Socket AM5 package, VideoCardz reports. The new processor lineup is being built to target two distinct classes of customers—small business servers, and data-centers selling small-size dedicated servers that were otherwise having to offer Ryzen chips. Intel currently has the Xeon E-2400 series "Raptor Lake-E" processors in the Socket LGA1700 package to target these exact kinds of customers. The EPYC 4004 series will be based on the same "Raphael" package as the Ryzen 7000 series, and will be a step up from the Ryzen PRO 7000 series. What sets the Ryzen PRO 7000 apart from the EPYC 4004 series are the target markets. The Ryzen PRO series target commercial desktops. Perhaps the biggest differentiator between EPYC 4004 and Ryzen PRO 7000 series is the support and warranty AMD provides to its server processors.

The "Raphael" package gives the EPYC 4004 series CPU core counts ranging between 6 and 16. These CPU cores are based on the "Zen 4" microarchitecture. The memory controllers in the I/O die will probably be reconfigured to support server memory densities, besides ECC support like on the Ryzen PRO 7000 series. There's even talk of variants with 3D V-cache, although it remains to be seen if the 12-core and 16-core variants are similar to the 7900X3D and 7950X3D, where only one of the two CCDs has 3D V-cache; or if they're the chip we all dreamed about—a "Raphael" with both CCDs featuring 3D V-cache. There are already Socket AM5 motherboards by companies such as Advantech, which are server-grade, with server-relevant I/O, like the one pictured below, and so the ecosystem for EPYC 4004 series already exists, along with upgrade headroom for future generations.

Very interesting, but I'm not sure what could this part mean?

ASRock Rack's AM5 "server" boards already support up to 192GB of ECC RAM with UDIMMs.
RDIMM support? Wouldn't that require a different IO die? Maybe more channels at the same time?

It literally says they will have a reconfigured IO die.

EPYC 4004 just seems like a terrible name... asking for bad things to happen lol

It literally says "probably" Since it's a rumor it doesn't matter that much.
Anyway my question was focused on what "to support server memory densities" even means in this context. UDIMMs used in consumer AM5 are not compatible with R/LR/3DS DIMMs used in servers.
I would be surprised if Ryzen 7000 IO die supported the latter standards. That's why I was wondering about a new/refreshed design, as in physically different silicon, of it. I'd be interested in a 16-core AM5 CPU on 3- or 4-channel board, but that would probably be eating into Threadripper non-PRO's territory.

It means servers supporting 2TB to 4TB of ram or more.

Maybe someone at AMD is on the nostalgia train? 4004 -> 8008 -> 8086 -> 8088 -> etc...

"We all"? Don't appreciate the hyberbole here.

I personally wanted the split design. The reason I skipped the 5800X3D is because I didn't want to compromise, some of my common tasks being better w/ vcache but some being worse. The split CCD design of the 7950X3D means I don't have to compromise, I can run my applications on whichever CCD is best for them (a simple matter w/ ProcessLassso). My only compromise now is that full 16-core workloads are a bit slower than a 7950X would have been, but I don't have many of those, and I'm still better off than if I had limited myself to an 8-core cpu.

I have no use case for vcache across all 16 cores. No game I play (or likely will play for the life of the cpu) will use that many cores.

The 80085 is my favorite line of processors.

They should also launch the Ryzen 8086G. There will never be a better time than right now.

Is this the same AM5 socket that's being used on consumer Ryzen motherboards? And if so, why? What's the goal here? I thought the server platform has its own bigger socket.

Eh... makes sense.
