FFmpeg devs boast of up to 94x performance boost after implementing handwritten AVX-512 assembly code (www.tomshardware.com)

Unfortunately, due to the complexity and specialized nature of AVX-512, such optimizations are typically reserved for performance-critical applications and require expertise in low-level programming and processor microarchitecture.

But my question is, how much faster is it that its written in assembly rather than "high" level language like C or Rust. I mean if the AVX-512 code was written in C, would it be 40% faster than AVX-2?
