I'm not saying that sounds right... I agree, it does not. I'm only reading what I see at Hashparty.io after looking at their stats for me. When I look at the GPU Rig itself, I see:
XMR: GPU0 381 H/s, GPU1 384 H/s, GPU2 385 H/s, GPU3 381 H/s, GPU4 376 H/s, GPU5 385 H/s
So - that would be more like 2,292 H/s
It's not like that for Ethereum, it is WAY higher. This is just how it runs against XMR, I'm guessing. For Ethereum each one is nearing 600 as I recall.
It is a 6-Rig, RX580
