Comment on HP and Dell disable HEVC support built into their laptops’ CPUs
AnUnusualRelic@lemmy.world 3 days agoI 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.

That is parallelized… I didn’t make mention of threading being the concern here.
The 100+ billion operations per second isn’t exactly easy.
4k 60fps = 498 million pixels per second
Each pixel takes a couple hundred logical operations with HEVC.
A modern high end 4GHz, 8 physical core CPU at 4 instructions per cycle, at maximum capacity, can handle 128 billion operations per second.
You probably wouldn’t even get your realtime framerate in this scenario.
