Not just Nvidia: GPU programming that runs everywhere
- akasakahakada 3y agoGPU is 10X slower than CPU. What am I missing here?
- itamarst 3y agoThere's overhead in transferring data from CPU to GPU and back. I'm not sure how this works with internal GPUs, though, insofar as RAM is shared. In general, though, as I understand it (not a GPU programmer) you want to pass data to the GPU, have it do a lot of operations, and only then pass it back. Doing one tiny operation isn't worth it.
