The default compiler flags and other optimizations really help Clear Linux out-of-the-box performance even on AMD EPYC.
It's too bad that Intel's Clear Linux had to come to an end as it was an exceptional example of the benefit of out-of-the-box software optimizations and how much further modern processors can be pushed with appropriate tuning.
In some of the LocalScore AI benchmarks that leverage Llama.cpp, Clear Linux came out in the middle on this AMD EPYC 9965 2P server -- likely due to the mentioned 512 thread kernel limitation.
👁 C-Ray benchmark with settings of Resolution: 5K, Rays Per Pixel: 16. AlmaLinux 10 was the fastest.
Even with the 512 thread limitation rather than all 768 threads for this beastly AMD EPYC server, Clear Linux still outperformed Ubuntu in those demanding tests.
