"AMD's advantage in Bitcoin mining was purely due to an architectural quirk" False. I authored a Bitcoin miner utilizing this quirk (bit_align). I was also the first to leverage another instruction exclusive to AMD (bfi_int): https://bitcointalk.org/?topic=2949 https://bitcointalk.org/?topic=2949 bit_align "only" gave AMD a 1.7x advantage over Nvidia. The biggest perf gains (2x-3x!) came from the fact AMD has more execution units: https://en.bitcoin.it/wiki/Why_a_GPU_mines_faster_than_a_CPU#Why_are_AMD_GPUs_faster_than_Nvidia_GPUs.3F https://en.bitcoin.it/wiki/Why_a_GPU_mines_faster_than_a_CPU...
