I know Michael is super busy, but I would love to see a BSD round up on a system with this many threads. FreeBSD vs DragonFly would be very interesting since they target high end high core count server/workstations like this but I would also like to see how OpenBSD and NetBSD perform on a system with this much horsepower especially since those projects haven't focused so much on extreme multithreading of the kernel as much as Free and DragonFly have. Might suggest using UFS as the file system in all tests so that ZFS and Hammer don't skew the results.

Fake? Check it for yourself if you don't believe it.
Clear Linux adds lots of optimization flags in order to be the fastest Linux distro ever.
Other distros don't do that.

All compiler flags were at their default. Clear does have more aggressive compiler flag tuning as pointed out countless times in many articles but in the x265 tests for instance that really isn't relevant in the case of openSUSE. OpenSUSE had the same default CFLAGS as the other non-Clear Linux distributions yet performed so poorly (it just doesn't show the numa flag due to no space to render).
You compile the x265 binary. Make sure you have *all* required dependencies installed. Your recipe lists yasm, but x265 requires nasm:
The Phoronix Test Suite open-source, cross-platform automated testing/benchmarking software. - phoronix-test-suite/phoronix-test-suite
You should include the output of configure/cmake/meson/whatever for all tools you compile yourself, so results can be verified.
For x265, it even reports the CPU extensions usable:
Code:x265 --version x265 [info]: HEVC encoder version 3.1.2+1-76650bab70f9 x265 [info]: build info [Linux][GCC 9.2.1][64 bit] 8bit+10bit+12bit x265 [info]: using cpu capabilities: MMX2 SSE2Fast LZCNT SSSE3 SSE4.2 AVX FMA3 BMI2 AVX2

8-Way Linux Distribution Benchmarks On The AMD EPYC 7742 2P Server
Phoronix: 8-Way Linux Distribution Benchmarks On The AMD EPYC 7742 2P Server
A few days ago I provided some benchmarks showing how running Intel's open-source Clear Linux on AMD EPYC Rome can provide some significant speed-ups over Ubuntu Linux, but how do other Linux distributions compare on AMD's new Zen 2 server processors? Here is an eight-way benchmark comparison on the AMD EPYC 7742 2P Daytona server with its 128 cores / 256 threads.
