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!
