Phoronix: ASRock Rack Releases BIOS Update For EPYC 4004 Support With AM5 Ryzen Boards

As a follow-up to this morning's AMD EPYC 4004 review and benchmarks, Supermicro, ASRock Rack, Giga Computing, Tyan, and others have announced new motherboards/servers for these entry-level EPYC servers. In addition with the likes of ASRock Rack they have already published BIOS updates enabling existing AM5 Ryzen server boards to officially support the EPYC 4004 series processors...

What's the difference between a normal Ryzen 7950X and an Epyc 4004 variant of the same CPU?

Intel for example offers the same CPUs in Xeon variant, but then under Xeon moniker it unlocks the ECC RAM capability.
AFAIK, AMD doesn't restrict ECC even in normal Ryzen CPUs, so what's different then?

which consumer boards will provide full ecc support with ecc memory and one of these CPU's?

It seems like it's genuinely the same underlying silicon, but instead has a different support mechanism from AMD, based on this servethehome article;

Official ECC support, BMC, and software raid

Ah... So nice to see that green motherboard. So, so good... I would definitely want to have that for my desktop when paired with Silverstone 5U RM52 rackmount chassis. No more consumer-looking motherboards and no more consumer-looking computer cases. I would love to hide that PC out of sight along with that green motherboard. I will only see a green motherboard when I take my computer offline and upgrade components such as a GPU.

Asrock again ahead of the curve on bios updates for compatibility

maybe we could get part3 article: a benchmark xeon E vs amd epyc 4004 with endless os?

Does Endless OS do anything real for performance? Last I knew they were mostly on desktop-related work and no real low-level optimizations?

In addition to what others have said, Epyc 4004 I think has a few more PCIe lanes. Most of the differences are in the motherboards though, where they'll be guaranteed to support ECC and where they'll be designed with server racks in mind. Kinda stupid that the CPUs are considered a different product when the mobo is what really matters here, but at least AMD isn't really changing the price much.
