The OpenVINO AI toolkit maintained by Intel showed modest scaling from the 128-core EPYC 9755 to 192-core EPYC 9965 processors. Except for the 144-core Xeon 6780E processors not performing well here due to the lack of AVX-512 or AMX found with Granite Rapids. The AMD EPYC 9965 has proven much more versatile than Intel's Sierra Forest for having real performance potential and value outside of just dense containers/microservices and the like. The Xeon 6980P Granite Rapids processors also benefited a lot with OpenVINO not only because of AMX but also MRDIMM-8800 memory.

👁 NAS Parallel Benchmarks benchmark with settings of Test / Class: BT.C. Xeon 6780E 2P was the fastest.

👁 NAS Parallel Benchmarks benchmark with settings of Test / Class: EP.C. EPYC 9965 2P was the fastest.

👁 NAS Parallel Benchmarks benchmark with settings of Test / Class: EP.D. EPYC 9965 2P was the fastest.

For NASA's highly scalable NAS Parallel Benchmarks, the Xeon 6780E 2P did pick-up a win for the Block Tridiagonal "BT" benchmark but when it came to the other NPB tests it quickly lost to the AMD EPYC Zen 5 server CPUs and the Xeon 6980P Granite Rapids server. The AMD EPYC Turin processors remained in the lead too when it came to delivering the best performance-per-Watt.
