With regards to the gpu hashing at 1000 h/s its a radeon pro duo
R9 390 hashes at 300 h/s with 40 compute units
Pro duo has 128 compute units hbm memory and tdp 300 watts
Is this your pro duo or are you speculating,I was under the impression pro duo was 2 furys so that would give us around 600 s/s max with Claymore!
Pro duo has 8gb hbm memory if a 295x2 can do 560 s/s at 88 compute units then its very easy for a pro duo to hit 1000 s/s as it has 128 compute units and faster memory access if you look at the fury pro thats coming out next year that uses hbm2 memory at 64 compute units which will sit inbetween the 295x2 and the pro duo the pro duo also has advanced power effeciency technology to allow it to only run at 300 watts thats the whole point of hbm memory
