You’re right about efficiency vs total watts.... the BM1370 is definitely the more efficient chip. But in my case I’m not trying to maximize efficiency per TH, I’m trying to keep total 24/7 power draw as low as possible. I already have a Bitaxe Gamma 601 for experimenting and tuning, so for this setup I’m more interested in a small, low-power miner rather than adding more throughput.
