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
