FFmpeg developers claim 94x speed boost using handwritten AVX-512 code

FFmpeg developers have demonstrated significant performance improvements in video processing using AVX-512 instructions and optimized assembly code. Handwritten assembly routines leveraging these advanced vector extensions can accelerate video decoding by 3 to 94 times. While only 8% of FFmpeg's codebase currently uses assembly language, there's potential for further optimization. Intel recently introduced AVX10, standardizing AVX-512 instructions across x86 CPU architectures, despite previously disabling AVX-512 support in newer consumer processors.
