gmh_2001:
Going to go back to this again as there's something wrong. Recently bought another 64core threadripper 3995wx (used) to complement my existing 3990x and 4 other 3970x machines. It really annoyes me that all 4 3970x machines are way faster than the 64 core machines at rendering!! All latest drivers, os builds, bios, Corona 11 (+hotfix), 3dsmax 2024.2, 10gbe lan, AC on all machines. There is something going on here as we've now tested this setup with win 10 and win 11.

your saying your 3970x is faster than your 3990x machines? What are both pulling in Corona benchmark. I'll compare to my 3990x.

gmh_2001:
The benchmarks are as normal with the 3990x and 3995wx pulling away. But real world is a very different story. I've even tried standalone render and the 3970x machines are faster on most projects. Temps are all good with all chips at spec frequencies during renders.

dfcorona:
Are you pulling assets from nas or over Ethernet? Are you rendering local on all? We can try a sample scene rendered on your be mine too see if there is a difference.

gmh_2001:
pulling resources from a dual epyc server (ms server 2019) -the drives are all nvme 4.0 and the connections are sfp+ 10gbe -across network with average transfers ~1GB up and down. The common factor is 64core machines (multiple) are being outperformed by 32 core machines (multiple)
