FFmpeg devs boast of up to 94x performance boost after implementing handwritten AVX-512 assembly code
Contemporary high-level programming languages and advanced compilers greatly simplify software development and lower its costs. However, this way of programming can hide the performance capabilities of modern hardware, partly due to inefficiencies of application programming interfaces (APIs). Apparently, a good old assembly code path can improve performance by between three and 94 times, depending on the workload, according to FFmpeg. The hardware this multiplied performance was achieved on was ...
