AMD EPYC 7642 Benchmarks: The Rome 48 Core CPU That Easily Takes On Intel's Xeon Platinum 8280
Starting the benchmarking roundabout with NAMD, the EPYC 7642 in both 1P and 2P configurations fits as it should within the EPYC Rome line-up. Interesting to note is that the EPYC 7642 was faster than the Xeon Platinum 8280 for NAMD both in single and dual CPU configurations.
With John The Ripper that scales very well with OpenMP, the 48 core / 96 thread EPYC 7642 nearly ties the dual Xeon Platinum 8280 with its combined 56 cores / 112 threads. Interestingly in this workload, the EPYC 7642 also nearly matches the previous-generation EPYC 7601 2P.
Even with Intel's own MKL-DNN deep learning benchmark that leverages their Math Kernel Library (MKL), the EPYC 7642 does a good job competing with the Xeon Platinum 8280.
