Interesting timing on posting this to HN, I've recently been optimizing my WebGPU LSD radix sort. Today I measured it against the Thrust CUDA version, and it's about 10x slower (15ms to 1.5ms). My goal was to try to get 10 million elements in 1 ms, but now that I know 3 million in 1.5ms is impossible even for Thrust I know I won't be able to beat that.
