AMD EPYC 9000 “Genoa” & Ryzen 7000 “Raphael” Zen 4 CPUs Reportedly Launching Together, 96-Core EPYC 9654 Pictured Too
The AMD Ryzen 7000 “Raphael” Desktop CPUs based on the Zen 4 core architecture are planned for an official announcement on the 29th of August with a launch planned for 15th of September. As per the leaker, the AMD EPYC 9000 “Genoa” Server CPUs are also reportedly going to debut the same day. Now, this isn’t a major deal considering both lineups are based on the same Zen 4 core architecture. But I think it would make more sense to have them announced on the same day on the 29th (August) followed by a launch later in the coming month.
— 结城安穗-YuuKi_AnS (@yuuki_ans) August 12, 2022 Having two products being announced on the same day isn’t as difficult to manage than to have two completely different product families launching at once. While the announcement can happen on the same day, the launch might take place a few days apart. Regardless of that, AMD having its EPYC 9000 “Genoa” family being announced as early as August means that they are definitely on schedule and will blow away Intel’s Sapphire Rapids-SP Xeon CPU lineup which has been delayed to 2023. AMD EPYC 9654 “Genoa” CPU Specifications AMD EPYC 9654 and will be part of the Genoa EPYC 9000 series family. The CPU will offer a total of 96 cores and 192 threads which is the maximum core count of the Genoa lineup. To get to 96 cores, AMD will be incorporating a total of up to 12 CCD’s in its Genoa chip. Each CCD will feature 8 cores based on the Zen 4 architecture. This is an increase of 50% in cores and thread count versus the Milan-X 64 core and 128 thread parts. But this isn’t the flagship SKU as that title is held by the EPYC 9664 which we also detailed here. In addition to the release dates, AMD’s EPYC 9654 “Genoa” CPU has also been pictured. This is a retail-ready chip and has the proper SKU name etched on the IHS. The AMD EPYC 9654 “Genoa” CPU will feature 32 MB of L3 cache per CCD which will be shared across all Zen 4 cores within the CCD and a total of 1 MB L2 cache per core. This gives us 384 MB of L3 cache and 96 MB of L2 cache which combine to offer a massive 480 MB of cache pool available on the top SKU. For comparison, the top EPYC Milan CPU, the EPYC 7763, packs 256 MB of L3 (32 MB per CCD) & 32 MB of L2 (512 KB per core) for a total of 288 MB combined cache. That’s a 67% increase in the amount of cache alone.
AMD EPYC 9654 (Genoa) - 384 MB L3 (32 MB Per CCD) + 96 MB L2 (1 MB Per Core) = 480 MB Cache AMD EPYC 7763 (Milan) - 256 MB L3 (32 MB Per CCD) + 32 MB L2 (512 KB Per Core) = 288 MB Cache
With that said, AMD’s EPYC 9000 “Genoa” CPU lineup for servers is going to offer a huge uplift in performance. We have already seen a partial 128 core / 256 thread configuration defeating all of the current-gen server chips so a 192 core and 384 thread dual-socket configuration is going to shatter some world records for sure. The AMD EPYC 9000 Genoa CPU lineup is expected to enter servers in the next few months.
