Fixed AVX CPU cores on a Mac means the processor locks certain cores to handle AVX-specific tasks consistently. This ensures stable performance for demanding applications like video editing or simulations. However, it may increase power usage and limit flexibility for lighter tasks. Macs with Apple Silicon handle similar workloads differently without explicitly using AVX cores.
When I worked on a project involving heavy video editing, I noticed how fixed AVX CPU cores on my Mac kept the performance steady, even during long rendering sessions. This setup ensured my workflow stayed smooth without unexpected slowdowns.
