Stockfish benchmark with settings of Total Time. Ubuntu 22.04 was the fastest.
asmFish benchmark with settings of 1024 Hash Memory, 26 Depth. Ubuntu 22.04 was the fastest.
Primesieve benchmark with settings of Length: 1e12. Windows 11 Home was the fastest.
Y-Cruncher benchmark with settings of Pi Digits To Calculate: 500M. Windows 11 Home was the fastest.
ASTC Encoder benchmark with settings of Preset: Fast. Ubuntu 22.04 + Linux 6.5 Git was the fastest.
ASTC Encoder benchmark with settings of Preset: Medium. Ubuntu 22.04 was the fastest.
ASTC Encoder benchmark with settings of Preset: Thorough. Windows 11 Home was the fastest.

Across a wide range of benchmarks the Windows 11 vs. Linux performance was much closer than I typically see... Either Windows 11 has been driving some new AMD optimizations or the Linux performance of the Phoenix SoCs aren't yet striking their full potential.

Blender benchmark with settings of Blend File: BMW27, Compute: CPU-Only. Ubuntu 22.04 was the fastest.
Blender benchmark with settings of Blend File: Classroom, Compute: CPU-Only. Ubuntu 22.04 was the fastest.
Blender benchmark with settings of Blend File: Fishy Cat, Compute: CPU-Only. Ubuntu 22.04 was the fastest.
Blender benchmark with settings of Blend File: Barbershop, Compute: CPU-Only. Ubuntu 22.04 was the fastest.
Blender benchmark with settings of Blend File: Pabellon Barcelona, Compute: CPU-Only. Ubuntu 22.04 was the fastest.

Blender at least is still showing very significant render time advantages when run on Linux rather than Windows.
