1EPYC-032: AMD EPYC 9004 CPUs support 12 channels of up to 4800 MHz DDR5 memory which is 460.8 GB/s of maximum memory throughput per socket. Intel Scalable “Ice Lake” CPUs support 8 channels of up to 3200 MHz DDR 4 (per https://ark.intel.com/) have a maximum 204.8 GB/s. EPYC 9004 CPUs have 2.25x the memory throughput per CPU. 460.8 ÷ 204.8 = 2.25x the max throughput or 125% more max throughput.
2EPYC-034A: AMD EPYC 9004 CPUs can support 12 memory channels with 2 DPC (DIMMs / channel) 12 x 2 = 24 DIMM slots x 256GB DIMMs = 6,144GB of standard DRAM (DDR) memory or 6TB per CPU. The highest supported total memory (not just DRAM) on https://ark.intel.com/ is the Intel Xeon Ice Lake is 6 TB per CPU - but with standard DRAM the limit is 4TB: 8 memory channels x 2 DPC = 16 total DIMM slots x 256GB DIMMs = 4,096GB of DRAM (DDR) memory, or 4TB per CPU. EPYC 9004 Series supports 50% more DRAM than Intel Ice Lake CPUs.
3EPYC-028B: SPECpower_ssj® 2008, SPECrate®2017_int_energy_base, and SPECrate®2017_fp_energy_base based on results published on SPEC’s website as of 11/10/22. VMmark® server power-performance (PPKW) based results published at https://www.vmware.com/products/vmmark/results3x.1.html?sort=score. The first 74 ranked SPECpower_ssj®2008 publications with the highest overall efficiency overall ssj_ops/W results were all powered by AMD EPYC processors. For SPECrate®2017 Integer (Energy Base), AMD EPYC CPUs power the first 4 of 5 SPECrate®2017_int_energy_base performance/system W scores. For SPECrate®2017 Floating Point (Energy Base), AMD EPYC CPUs power the first 8 of 9 SPECrate®2017_fp_energy_base performance/system W scores. For VMmark® server power-performance (PPKW), have the top two results for 2- and 4-socket matched pair results outperforming all other socket results.
