PhoenixMiner 2.8c tested on AMD and NVIDIA rig, my observations are:
Nvidia rig works 3-5Mhs more then Claymore 11.5  P106 runs 25.7-26.1, GTX1070 33.2 GTX1060 24.1
AMD rig on RX570 8GB have 2Mhs less around 29, claymore have 31+ and little less on RX 470 around 32.6, claymore 11.6 have 32.8
On awesomeminer dont see Progress on Nvidia card how many accepted, Rejected...
I have problems on NVIDIA P106 cards, with fan controls, does not show a percentage, got error after few minuts
with some fixes, the program will be really good
