With OpenFOAM 10 computational fluid dynamics (CFD) software, even the c2d-highcpu-8 instance matched the c3-highcpu-8 Sapphire Rapids performance.

OpenRadioss benchmark with settings of Model: Bumper Beam. t2d-standard-8 AMD was the fastest.

The AMD EPYC Milan VMs were proving to deliver much better performance than I expected against Sapphire Rapids in Google's Cloud. The very strong Tau T2D performance wasn't out of the ordinary with being backed by eight physical cores but even the C2D instance with 4 CPUs + SMT like the tested Intel instances it often was coming close to or matching the new C3 VM speeds.

Zstd Compression benchmark with settings of Compression Level: 19, Compression Speed. c2d-highcpu-8 AMD was the fastest.
Zstd Compression benchmark with settings of Compression Level: 19, Decompression Speed. c2d-highcpu-8 AMD was the fastest.
John The Ripper benchmark with settings of Test: bcrypt. t2d-standard-8 AMD was the fastest.
John The Ripper benchmark with settings of Test: MD5. c3-highcpu-8 SPR was the fastest.

I even repeated some of the tests after being so surprised by the EPYC Milan vs. Xeon Sapphire Rapids performance with Google Compute Engine, but the results held.
