AMD EPYC 9965 "Turin Dense" Delivers Better Performance/Power Efficiency vs. AmpereOne 192-Core ARM CPU


Complementing the AMD EPYC 9575F / 9755 / 9965 performance benchmarks article looking at those Turin processors up against prior AMD EPYC CPUs and the Intel Xeon competition, this article is looking squarely at the 192-core EPYC 9965 'Turin Dense' processor compared to Ampere Computing's AmpereOne A192-32X flagship processor.

This article is on its own separate from the other EPYC and Xeon comparisons due to a subset of the benchmarks/workloads being in good shape / similar quality on AArch64. The AmpereOne A192-32X features 192 cores, a 3.2GHz clock frequency, 64MB cache, 128 lanes of PCIe Gen 5, and eight channel DDR5-5200 memory while having a rated usage power of 276 Watts. If AmpereOne had been readily available even one year ago it would have been going up against the 128-core Bergamo at the top end and would have been out before Intel's 144-core Sierra Forest processors, etc.
