I Have Tested The Miner Vs Claymore 11.3
Hash Speed With Claymore 11.3
RX580 8GB MSI = 968 hashes 1200/2000
RX580 8GB GTS = 1024 hashes overclocked core to 1315 mem 2100

RX570 8GB MSI = 974 hashes 1200/2000
RX580 4GB GTS = 825 hashes 1200/1950

Hash Speed With SRBMiner v1.5.9
RX580 8GB MSI = 994 hashes core 1200/2000

RX580 8GB GTS = 998 hashes core 1200/2000

RX570 8GB MSI = 995 hashes core 1200/2000

RX580 4GB GTS = 955 hashes core 1250/1950

I do have my own custom bios For all cards so results may not be the same for everyone but these are the best i could get
in my comparison the two miners or the best but SRBminer with a 4 card gpu rig hases at 3980 hashes compared to 3860 hashes with claymore 11.3
now all we need is a linux version of this miner so i can run it on my SMOS rigs
so untill that happens im stuck with Claymore 11.3 and SRBminer on my 2 Windows Rigs
so as far as the fastest miner goes SRBminer Hands Down Is the King in my book
