AMD EPYC 7773X "Milan-X" Benchmarks Show Very Strong HPC Performance Upgrade
Now with having looked at how the AMD EPYC 7773X 2P performance compares with 3D V-Cache on/off, let's have a look at how the EPYC 7773X in both 1P and 2P configurations compare against other CPUs. For this comparison is the AMD EPYC 7713, EPYC 7763, EPYC 7773X, and Xeon Platinum 8380. All processors were tested in both 1P and 2P configurations.
As mentioned, all testing was done on an Ubuntu 22.04 snapshot with the Linux 5.15 kernel and GCC 11.2 compiler for an up-to-date look at how the Intel/AMD server performance is ahead of next month's LTS release.
For high performance computing workloads where the EPYC 7763 was already leading over Intel's Xeon Platinum 8380 "Ice Lake" processors, the lead is only now extended further in AMD's favor with the EPYC 7773X. For some of these tests depending upon their scalability, the EPYC 7773X 1P was even more of a smashing hit.
For the WRF weather forecasting workload, the EPYC 7773X was providing considerable time-savings over the EPYC 7763. The EPYC 7773X 2P shaved around 13% off the run-time of the EPYC 7763 2P with the conus 2.5km model, or about 17 minutes less per run. The EPYC 7773X 2P was finishing the conus 2.5km model about 42 minutes quicker than the Intel Xeon Platinum 8380 2P.
The EPYC 7773X 2P configuration was still consuming less power on average than the Xeon Platinum 8380 2P processor configuration as well as having a lower peak power consumption during the WRF testing.
With the EPYC Milan-X processors only costing slightly more than the existing Milan variants, they provide good value still and out ahead of the Xeon Platinum 8380 processors at their list price -- though at the moment the Xeon Platinum 8380 processors are retailing well above the list price too.
