Yes the current crop of GPUs currently in use I know nvidia likes equihash but im not sure how they compare efficiency wise although they are supposed to be lower power consumption per hash
All I have are AMD cards mainly RX480s 8GB and a couple of 4GB variants
RX should do around 300 sols
Nvidia 1070 430-450 range
I don't remember power consumption from the wall but either way Nvidia is better for sure.
