The full AMD EPYC Genoa CPU lineup and performance benchmarks have leaked out showcasing what the next-gen Zen 4 server lineup has to offer.

AMD EPYC Genoa "Zen 4" CPU Lineup & Benchmarks Leak Out, Showcases Over 2x Performance Gain Over Intel Xeon & Previous Gen EPYC Chips

The AMD Zen 4 lineup will be split into three families, the standard Zen 4 for EPYC Genoa, the Compute Density-Optimized Zen 4C for EPYC Bergamo, and the Cache-Optimized Zen 4 V-Cache within the EPYC Genoa-X series. Furthermore, the lineup will be featuring a cost-optimized and entry-level server offering known as EPYC Siena which will feature the same Zen 4 cores but on an entirely new platform known as SP6 which will once again focus on optimizing TCO compared to SP5. The lineup will be branded under the EPYC 8004 family. We covered the initial specs for the Zen 4 server family here already.

AMD EPYC Genoa "Zen 4" Server CPU Lineup

The standard Zen 4 lineup will feature up to 12 CCDs, 96 cores, and 192 threads. Each CCD will come with 32 MB of L3 cache and 1 MB of L2 cache per core. The EPYC 9004 CPUs will pack the latest instructions such as BFLOAT16, VNNU, AVX-512 (256b data path), addressable memory of 57b/52b, and an updated IOD with an internal AMD Gen3 Infinity Fabric architecture with higher bandwidth (die-to-die interconnect).

The platform will feature support for 12 DDR5 channels with up to 4800 Mbps DIMM support and include options for 2,4,6,8,10,12 interleaving. Both RDIMM & 3DS RDIMM will be supported with 2 DIMMs per channel for up to 6 TB/ capacities per socket (using 256 GB 3DS RDIMMs). There will be 160 gen 5 lanes available on the 2P platform, 12 PCIe Gen 3 lanes (8 lanes on 1P), 32 SATA lanes, & 64 IO lanes supporting CXL 1.1+ with bifurcations down to x4 and SDCI (Smart Data Cache Injection).

AMD EPYC Genoa "Zen 4" Server CPU Performance

In terms of performance, the leaked charts showcase the SPEC2017 Integer (Base) benchmarks for 14 chips within the AMD EPYC Genoa lineup. At least five of the chips sit above 1000 points while the rest are positioned competitively in the mid-tier and entry-tier segments. All benchmarks were done on a 2P (dual-socket) platform so two chips are used.

The charts also provide comparative data against Intel's flagship Ice Lake-SP Xeon, the Platinum 8380, and the flagship EPYC Milan chip, the 7763. The AMD EPYC 9654 CPU is up to 2.6x faster than Intel's Xeon and over 2x faster than AMD's EPYC Milan CPU while also offering 1.7x the performance per watt which is very impressive if true.

'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 by the end of this year.
