This doesn't reflect my experience. We moved some monte-carlo implementations from CPU to GPU starting around the time this article was written. The CPU implementations had had significant optimisation work done on them because it had to run on 10k+ cores so even small improvements had significant cost implications. The GPU implementation ran about 40-50x faster for the same accuracy. We didn't need that speed up in practice so we traded some of it for more paths.
