From the project
Bitaxe with Whatsminer KF1950
- Bitmain claims the BM1370 has 15 J/TH efficiency. We can get pretty close to that with the BitaxeGamma - The Antminer S21 Pro has a nominal hashrate of 234 TH/s. There are 3 hashboards with 65 chips each, for a total of 195 chips. The bitaxeGamma has a single one of these chips. That means about 1.2 TH/s per bitaxeGamma. Initial testing looks good! - The BM1370 is brand new and isn't available individually yet. The best place to get these chips is right out of a S21 Pro. - The BM1370 has a different footprint and pinout from the BM1368, BM1366, BM1397 and BM1387 in previous bitaxe.
