Yeah, because of the ASICs built into them to enable that decoding.
Without that, a 4K HEVC video is in upwards of 100+ billion operations/s to decode on the CPU. Which limits you to high end CPUs getting capped out on something you essentially get for "free" otherwise
I meant without dedicated circuits, obviously. Can't it be parallelised? Many cpus have a lot of relatively idle cores at a given time...
I remember that my 486 had trouble with mp3 files, but soon enough, I got a new machine with many more spare cycles.
