AMD Epyc 4004 - the Potential Ryzen Killer

in General
AMD announced a new breed of CPUs named AMD Epyc 4004. These CPUs have the same core counts, clock speeds, with and without 3D VCache, and everything else as Ryzen CPUs. So perhaps real-world performance would be similar to Ryzens, with the possibility of performing better on server hardware.
The added benefit is that, unlike Ryzens, these are validated for server operating systems and software.

Every single specification is the same as the Ryzen processors with the exception of the 4 core variant. Even down to the base clocks, boost clocks, and 3D V-Cache.
That's why I am excited. We have been using Ryzens and replaced our entire fleet of Xeons after AMD released Zen 3.
Even though AMD markets Ryzens as both server-grade and consumer-grade, they lack official validation. Now, they have an AMD Epyc Ryzen with validation.
I hope it performs as well as Ryzen. If it does, it will shake the data center market.
TDP? Usually EPYC consume way more power than Ryzen. It is not believable that AMD would cut the tree branch while sitting on it.
Not really:
- Ryzen 9 7950X (16c, claimed 170W TDP) vs
- EPYC 9654P (96c, 360W TDP)
EPYC have way higher density and lower TDP per core.
But if core count is the same?

Still, it is not higher (170W TDP for both 16c CPUs)
Idle power consumption is usually a bit higher on EPYC CPUs due to the large number of memory controller channels, extensive I/O and chiplet design.
But as @tentor says, it should be insignificant given the much higher density. I'm quite excited about these chips. We have a few customers who don't need the raw performance of the regular EPYC chips, but unvalidated Ryzens aren't an option either.
Ryzen supports upto 192GB. What about the max memory supported for these Epycs?
Potentially more. Ryzen has 24 PCIE lanes, Epyc - 28. I'am still confused why AMD will do such stunt...
Epyc 4004 series supports max 192 GB the same as Ryzen from the linked phoronix article.
Every feature is the same as Ryzen except it has validation.
Just noticed this the other day, the ASRock B650D4U already has a beta BIOS with support for this EPYC 4004 series as well.
Rebadged ryzen.
It's just good for the few companies who still say "Yee ol desktop CPU is shit for server use".
