AMD is expected to introduce its mainstream server family in the form of EPYC 4004 CPUs which will be compatible with the AM5 platform.
AMD EPYC 4004 CPUs Coming To Mainstream AM5 Platforms In Standard & X3D 3D V-Cache Flavors
The information comes from @AnhPhuH who reports that AMD is working on a new EPYC family under the 4004 series. So far, AMD has its Zen 4-powered EPYC 9004 & 8004 families which are designed for SP5 & SP6 platforms respectively, and offer up to 128 cores. The EPYC 4004 will be AMD's third official series and will target the mainstream AM5 platform.
The AMD EPYC 4004 CPUs are expected to utilize the same Zen 4 core architecture & will probably utilize the same "Raphael" CPU dies that we have seen in the form of Ryzen 7000 and Ryzen 7000 X3D chips. The platform will only be configured in 1P (single-socket) solutions, unlike the high-end SP5 platforms which can house up to two sockets.
There is no information available on the launch date or the specific SKUs but it looks like the AMD EPYC 4004 CPU family will include both standard and X3D "3D V-Cache" boosted chips. So we can expect up to 16 cores and 32 threads along with 144 MB of cache. The most interesting aspect of these CPUs is definitely the fact that they will be supported by the AM5 platform but it is unknown if the chips will be compatible with DIY motherboards that you can get off shelves.
What to expect from the AMD EPYC 4004 platform:
- Socket Compatibility With AM5
- Based on Zen 4 Core Architecture
- 1P (Single-Socket) Support
- 3D V-Cache & Standard Variants
- Up To 16 Cores & 32 Threads?
- Up To 144 MB Cache?
We know that with the WRX80 platforms, only AMD's Ryzen Threadripper & Threadripper PRO CPU SKUs are compatible while the EPYC lineup isn't even though they are very similar in terms of CPU architectures and configurations. So that might end up being the same case for the EPYC 4004 CPU family. As for when these CPUs would launch, we can expect AMD to roll out some information in a few weeks or even days since it shouldn't take too long to release Zen 4 parts since they have been in mass production for quarters.
