overclocking Samsung memory on my GTX1066 G1 Gaming would make some 512 H/s and that means algo for AMD cards where 580 would give 1.2 kH/s. It doesn't even look like GPU based algo because I'v seen Xeons do the same 500+ H/s. Also they got ASICs now so ppl have invented Cryptonite-heavy still this algo sucks pendulum but now it consumes so much memory so only 8 Gb 580 could manage it without hashrate drops I hope all Cryptonite coins would prosper so all AMD cards switch there and leave the rest to Nvidia
