Ever wanted a cheap entry into the world of EPYC? AMD is announcing its first DDR5 entry-level processors, based on the consumer AM5 platform but with suppor...
Not really. It’s just a normal Zen 4 CPU with some server features like ECC memory support.
The biggest downfall of these chips is they have the same 28 PCI-E lanes as any consumer grade Zen 4 CPU. Quite the difference between that and the cheapest EPYC CPUs outside the 4000 series.
You’re going to run in to some serious I/O shortages if trying to fit a 10gbe card, an HBA card for storage, and a graphics card or two and some NVME drives.
A lot of the Zen based APUs don’t support ECC. The next thing is if it supports registered or unregistered modules - everything up to threadripper is unregistered (though I think some of the pro parts are registered), Epycs are registered.
That makes a huge difference in how much RAM you can add, and how much you pay for it.
Not officially. Only Ryzen Pro have official (unregistered) ECC support and not many motherboards support it either. AFAIK Threadripper doesn’t officially support it either but I could be wrong.
Agreed the PCI layout is bad. My problem is the x16 slot.
I would prefer 8 slots/onboard with PCIe5 x2 from CPU. From the chipset 2 slots of PCIe4 x2. This would probably adequate IO. Aiming for 2x25 Gbits performance.

I’m pretty sure all the Zen CPUs have supported ECC memory, ever since the first generation of them.

Many boards support ECC even when not mentioned. Most ASUS and ASRock boards do for example.
The newest Threadripper 7000 series not only support ECC, but require it to work. It only accepts DDR5 registered ECC RAM.
Consumer CPUs were lacking ECC reporting, so you never really knew if ECC was correcting errors or not.
