1. Lift is algorithm specific (some coins have a 512bit state and some have a 256bit state). Each Acorn can provide a MAX of around 30MH of lift to algorithms with a 512bit state, and 60MH for algorithms with a 256 bit state. That is irrespective of the number of GPUs. Power consumption of Acorn at peak is 15W. The limit is PCIe bandwidth, which for this generation of Acorn is PCIe 2.0 x4 = 20Gbps nominal, which yields an effective rate of 16Gbps after accounting for overhead. That math will then get you to the 33MH @ 512bit state, less 10% for safety and underpromising.
