FFmpeg developers have achieved a significant performance boost by implementing handwritten AVX-512 assembly code. The optimized code path, which has rarely been done before in the video industry, resulted in a speedup of up to 94 times compared to standard implementations. This development is particularly valuable for users running on high-performance, AVX-512-capable hardware, enabling them to process media content more efficiently.
However, it's worth noting that Intel disabled AVX-512 for its Core 12th, 13th, and 14th Generations of Core processors, leaving owners of these CPUs without access to this optimization. On the other hand, AMD's Ryzen 9000-series CPUs feature a fully-enabled AVX-512 FPU.
