GROMACS benchmark with settings of Implementation: MPI CPU, Input: water_GMX50_bare. x86-64-v3 ISA Optimized was the fastest.
TensorFlow benchmark with settings of Device: CPU, Batch Size: 512, Model: ResNet-50. x86-64-v3 ISA Optimized was the fastest.
RocksDB benchmark with settings of Test: Random Read. x86-64-v3 ISA Optimized was the fastest.
RocksDB benchmark with settings of Test: Read Random Write Random. x86-64-v3 ISA Optimized was the fastest.
Speedb benchmark with settings of Test: Random Read. x86-64-v3 ISA Optimized was the fastest.
OSPRay Studio benchmark with settings of Camera: 3, Resolution: 4K, Samples Per Pixel: 16, Renderer: Path Tracer, Acceleration: CPU. x86-64-v3 ISA Optimized was the fastest.
OSPRay benchmark with settings of Benchmark: particle_volume/ao/real_time. x86-64-v3 ISA Optimized was the fastest.
OSPRay benchmark with settings of Benchmark: particle_volume/pathtracer/real_time. x86-64-v3 ISA Optimized was the fastest.

I for one am very hopeful Red Hat Enterprise Linux 10 will go full bore on x86-64-v3 packages. There are nice gains in performance with x86-64-v3 -- as we've also seen with x86-64-v3 packages on other Linux distributions -- and realistically those pre-AVX/AVX2 servers still in production in 2025+ are probably unlikely to be upgraded to RHEL 10 as they are likely there for mature/legacy purposes. It would also be tantalizing if the CentOS ISA SIG experimented with offering x86-64-v4 packages for AVX-512 servers.
