Avalon Nano 3S vs Bitaxe Gamma

The Avalon Nano 3S hashes about 5 times faster than the Bitaxe Gamma, so its chance of finding a block is about that many times higher. It also draws about 7.8 times the power (140 W against 18 W). Per terahash, the Bitaxe Gamma is the most efficient at 15 J/TH. The Bitaxe Gamma is the cheapest to buy, from about $110.
