- Const-me 2y agoI don’t believe many people encode or especially decode video with CPU-running codes. Modern GPUs include hardware accelerators for popular video codecs, these are typically way more power efficient than even AVX-512 software implementations.

Believe what you want but as soon as realtime is not a concern and quality matters you'll be using CPU-based encoders unless you have special hardware for your use case. > Modern GPUs include hardware accelerators for popular video codecs ... with shit quality encoders because they are designed for speed first. Decoding is a different matter but even there older hardware can easily end up not supporting codecs (or profiles of them) that you come accross.
