Not sure if anyone will read this but I'm interested to see what is the fastest x11 gpu miner these days ? I've seen numbers like 15 and 25mh from an r9 290/390 but I can't replicate them in any way. Most I could do is 9.1mh on r9 390 and 6.6mh on r9 280x with nicehash sgminer 5.4 on win7 x64 15.12/15.7.1/16.1.1 drivers (they all have the same speed). Tried wolf bins too but they couldn't go above 7mh on r9 390. If anyone knows what are the best miners for x11 now please reply. thanks!
AFAIK, hardware miners (ASIC) are now mainstream for X11, so i'm not sure mining with GPU is profitable anymore.
Where did you see 15 and 25 mh?
