minus-squareAnUnusualRelic@lemmy.worldlinkfedilinkEnglisharrow-up1·20 hours 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.
minus-squaredouglasg14b@lemmy.worldlinkfedilinkEnglisharrow-up2·14 hours agoThat 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.
