AMD has officially confirmed that the 4th Gen EPYC CPUs, codenamed Genoa, will be introduced next month. The new generation EPYC “Genoa” processors are expected to experience a big leap in performance. In particular, the contribution and scalability of the Zen 4 architecture will be quite large.AMD EPYC 9000 Genoa roadmap
AMD’s server-side Zen 4 roadmap will maintain the standard architecture for the EPYC “Genoa” family. In the EPYC “Bergamo” generation, there will be a transition to Zen 4C with an optimized computing cluster. On the other hand, we will see the Zen 4 V-Cache design, which comes with optimized caches, in the EPYC “Genoa X” series. In the statement released by AMD today, it was stated that the 4th Generation EPYC processors will be introduced at the event to be held on November 10.AMD EPYC 9000 “Genoa” series features
The standard Zen 4 series will have 12 CCDs, 96 cores and 192 threads. Each CCD will come with 32MB of L3 cache and 1MB of L2 cache per core. EPYC 9004 processors will support packaging and instruction set technologies such as BFLOAT16, VNNU, AVX-512 (256b bus), 57b/52b addressable memory. However, an updated IOD with a higher bandwidth internal AMD Gen3 Infinity Fabric architecture will be embedded in Genoa processors.The platform will support DIMMs up to 4800 Mbps and 12 DDR5 channels. In addition, 2,4,6,8,10,12 interleaving options will be available. For capacities up to 6TB per socket, both RDIMM and 3DS RDIMM will be supported with 2 DIMMs per channel. On the other hand, the 2P (dual socket) platform will have 160 gen 5 lanes and 12 PCIe gen 3 lanes. There will also be 32 SATA and 64 IO lines.
AMD’s EPYC 9000 “Genoa” CPU series for servers aims to achieve a huge increase in performance. Preliminary information from EPYC 9000 also shows that these expectations will be met. The AMD EPYC 9000 series is expected to hit servers by the end of this year, while Intel’s Sapphire Rapids-SP Xeon series is expected to arrive in early 2023.
