@Ryan the 8534PN is listed as having both 128 cores and 128 threads and the 8024P 's pricing is missing the dollar sign. Thanks for your articles.Reply
We use 16 core EPYC CPUs in tower servers in our schools (although we are moving to 2U rackmount systems where we have space for a proper rack). Will be interesting to see how the pricing compares for 8004-based systems.
> Otherwise, since AMD is using the same IOD as their other EPYC parts, many of the limitations and trade-offs with those parts remain. The highest supported memory speed is DDR5-4800, which can only be hit with 1 DPC.
Wendell of Level1Techs recently tested a new Tyan server with an EPYC 9554 (so Genoa, not Siena). When updated with the latest BIOS and AGESA the system worked flawlessly with 2 DPC DDR5-4800.
2 DPC capabilities may be down to motherboard and IOD quality plus what the system manufacturer is confident allowing thru the firmware.
While Siena is unlikely to get the best IO dies, there will be some EPYC 9000 systems at least where the stated 1 DPC limitation no longer applies.Reply

AMD needs to stop comparing Epyc to Xeon. They need to compare to Ampere. When they do, this CPU looks a lot worse. ReplyHul8 - Tuesday, September 19, 2023 - link
