AMD EPYC 4004 CPUs Launched

AM5-socket Dual-channel Epyc CPUs with between 4 and 16 cores, ranging from 65 to 170W, and with a top speed of 5.7GHz. $149 to $699. Since they're on AM5, you get dual-channel RAM and "up to 28 PCIe 5" lanes. Up to DDR4-5200 MT/s RAM with ECC and 192GB capacity.

The slides say "optional USB4 add-in". The IOD, like the Ryzen one, has an RDNA2 iGPU, probably with only CUs but I didn't see a number. The slides show this aiming at the Xeon E2400 series.

Finally a successor to the Epyc embedded lineup.
My 3251s have been champs, but they are tired.

Agreed, I've been wanting to go with the EPYC Embedded platforms, but they are extremely dated at this point and especially so at the available price options.

The 4584PX looks like fun at 120watt TDP. Been considering a game server for home and that very well could be it.

Is the only difference between these and the consumer parts ECC support?

No, most of the consumer parts have ECC, too.

Sort of but not really, the 7000 series supports ram that has ECC but only unbuffered and unregistered.
So you can run the systems with ECC memory, but it will ignore the ECC functionality.

DDR5 has some small degree of built in single bit error detection but it operates at a software level and lets the OS determine how to handle it.

so what's the benefit of using this instead of a ryzen? just more pcie lanes?

Same # of lanes: 24 usable PCIe 5. I'm guessing the benefit is "you can use consumer motherboards."

Same number of PCIe lanes as the 7000 series, it has the secure memory controller and better support for memory. Put 4, 48GB sticks in a consumer 7000 series chip and try to boot, you will spend a lot of time trying to make that work.
Also that 128MB in L3 Cache

It’s just a good platform for lots of small VM’s.

The 4584PX has 64 megs of L3 cache per CCD.

Does it? Isn't it mostly a rebranded 7950x3d, so one CCD has 32M and the other has 96M? Plus whatever memory controller differences.

 

[learners permit]

Yea that may be the case but I hope not. I won't consider it if that's the case. Not enough details at this point to be sure.

"The AMD EPYC 4484PX and 4584PX feature AMD 3D V-Cache™ technology, with up to 128GB of L3 cache, enabling a significant performance boost for select workloads."

Edit: FWIW, TechPowerUp agrees:

"Level 3 cache arranged as 2x 32MB 2D cache plus 1x 64MB 3D V-Cache."
