Profitability Comparison
Canaan Avalon Nano 3S
StrongU STU-U8 Pro
Based on BTC price of $79,090 and current network difficulty as of May 15, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Canaan Avalon Nano 3S edges it: 4 of 5 factors go its way (efficiency, power consumption, home mining score, noise level). Where it pulls away hardest is 95% better power draw (140 vs 2,800 W). The StrongU STU-U8 Pro holds the edge in hashrate. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
