Quite well since that's up there with the fastest. I haven't quite benchmarked the new algorithm extensively (because it's not completely optimized yet) but it's about 1000 times more intensive than the last method on CPU. And the changes should make GPUs not a viable option for some time. It's utilizing SHA256 and one of the new SHA-3 candidates "BLAKE" along with some other features which the CPU is better at handling than GPU.
