Comment on Ask HN: A is faster than B on GPU but vice versa on CPUComments−MichaelCrawford11yDisk I/O. The GPU would have to ask the CPU to do much of the work. I expect that in principle a storage controller can DMA into the GPU's VRAM, but I don't know that anyone actually does that. maybe for texture maps.
