As this is just an early look at Ubuntu 22.10 vs. Clear Linux on the Core i9 13900K prior to the much larger Linux distribution comparison, let's get straight to the side-by-side data:\

To no surprise at this stage, Intel's Clear Linux has some very strong wins over Ubuntu 22.10 on this Raptor Lake desktop. Clear Linux having made a quick transition to Python 3.11 also now allowed it to pickup some big wins in a number of Python benchmarks. But in addition for complex, real-world workloads around AI with Microsoft ONNX and other programs all saw hefty gains thanks to the investments made by Intel into Clear Linux tuning. Clear's optimized PHP packages also paid off big time for better PHP performance, and more. These are the benchmarks with a measurable difference between these Linux distributions.

Out of 191 tests ran in total, Clear Linux was in first place 72% of the time while the times that Ubuntu 22.10 picked up victories tended to be by very tight margins.

If taking the geometric mean of all 191 benchmarks on both Linux distributions, Clear Linux was about 8% faster overall than Ubuntu 22.10.

Clear Linux doesn't rock just only on Intel x86_64 but Clear Linux is running remarkably well with the AMD Ryzen 7000 series (https://www.phoronix.com/review/zen4-clear-linux) CPUs that now have AVX-512 while Intel's Clear Linux has long carried optional AVX-512 code paths for their Xeon processor support.
