Cpu days are way behind.
Bis algo is not memory bound, pure raw hash is needed, so SIMD with massive thread count wins. Large advantage to GPUs.
Thanks for the explanation. I guess being memory intensive is the main solution for cpu friendly algos so that gpus don't take the advantage.
You can try to play with the specifics of some hardware to slow down others, but in practice, it's not that easy.
You can always trade space (ram) for speed for instance.
But yep, some try to use I/O bound operations, heavy memory use and serialized algos to limit gpus or asic advantage.
