AMD EPYC Genoa “Zen 4” CPU Lineup Specs & Benchmarks Leaked, Up To 2.6x Sooner Than Intel Xeon & 2x Sooner Than Milan With 1.7x Perf Per Watt

The complete AMD EPYC Genoa CPU lineup and efficiency benchmarks have leaked out showcasing what the next-gen Zen 4 server lineup has to supply.

AMD EPYC Genoa “Zen 4” CPU Lineup & Benchmarks Leak Out, Showcases Over 2x Efficiency Acquire Over Intel Xeon & Earlier Gen EPYC Chips

The AMD Zen 4 lineup shall be cut up into three households, the usual Zen 4 for EPYC Genoa, the Compute Density-Optimized Zen 4C for EPYC Bergamo, and the Cache-Optimized Zen 4 V-Cache inside the EPYC Genoa-X collection. Moreover, the lineup shall be that includes a cost-optimized and entry-level server providing referred to as EPYC Siena which can function the identical Zen 4 cores however on a completely new platform referred to as SP6 which can as soon as once more give attention to optimizing TCO in comparison with SP5. The lineup shall be branded below the EPYC 8004 household. We coated the preliminary specs for the Zen 4 server household right here already.

The usual Zen 4 lineup will function as much as 12 CCDs, 96 cores, and 192 threads. Every CCD will include 32 MB of L3 cache and 1 MB of L2 cache per core. The EPYC 9004 CPUs will pack the newest directions reminiscent of BFLOAT16, VNNU, AVX-512 (256b information path), addressable reminiscence of 57b/52b, and an up to date IOD with an inside AMD Gen3 Infinity Material structure with larger bandwidth (die-to-die interconnect).

The platform will function help for 12 DDR5 channels with as much as 4800 Mbps DIMM help and embody choices for two,4,6,8,10,12 interleaving. Each RDIMM & 3DS RDIMM shall be supported with 2 DIMMs per channel for as much as 6 TB/ capacities per socket (utilizing 256 GB 3DS RDIMMs). There shall be 160 gen 5 lanes obtainable 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 all the way down to x4 and SDCI (Sensible Knowledge Cache Injection).

AMD EPYC Genoa “Zen 4” Server CPU Efficiency

When it comes to efficiency, the leaked charts showcase the SPEC2017 Integer (Base) benchmarks for 14 chips inside the AMD EPYC Genoa lineup. At the very least 5 of the chips sit above 1000 factors whereas the remainder are positioned competitively within the mid-tier and entry-tier segments. All benchmarks have been finished on a 2P (dual-socket) platform so two chips are used.

The charts additionally present comparative information towards Intel’s flagship Ice Lake-SP Xeon, the Platinum 8380, and the flagship EPYC Milan chip, the 7763. The AMD EPYC 9654 CPU is as much as 2.6x quicker than Intel’s Xeon and over 2x quicker than AMD’s EPYC Milan CPU whereas additionally providing 1.7x the efficiency per watt which may be very spectacular if true.

AMD EPYC 9000 Genoa CPU SKUs ‘Preliminary’ Specs:

‘AMD’s EPYC 9000 “Genoa” CPU lineup for servers goes to supply an enormous uplift in efficiency. Now we have already seen a partial 128-core / 256-thread configuration defeating all the current-gen server chips so a 192-core and 384-thread dual-socket configuration goes to shatter some world information for positive. The AMD EPYC 9000 Genoa CPU lineup is anticipated to enter servers by the tip of this 12 months.
