I see no mention of simd in these threads. The only thing that has made high data throughput possible is vector operations. What's the performance of libjpegturbo or hevc in software?
- lern_too_spel 6y agoIt supports NEON like most phone CPUs. The new thing for a desktop is sharing memory for the CPU and GPU with a much faster bus instead of having the GPU sit on a slower bus with its own fast memory, so if your workload can benefit from using the GPU, you don't have to worry about host to device transfer.
- mhh__ 6y agoI can't find a number for it on M1 but I'm guessing a memory to SIMD register move is still a lot faster than faster CPU-GPU shared buffers, i.e. Even if it is a powerful tool it won't scale in the same way.
- hrydgard 6y agoApple CPUs have great NEON performance, so if those libraries have NEON paths, they'll scream.
