Profitability Comparison
Antminer T21
Innosilicon T2 Turbo 25T
Based on BTC price of $63,093 and current network difficulty as of Jun 4, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Antminer T21 edges it: 4 of 5 factors go its way (efficacité, hashrate, score de minage domestique, niveau sonore). Where it pulls away hardest is 660% more hashrate (190.0 vs 25.0 TH/s). The Innosilicon T2 Turbo 25T holds the edge in consommation électrique. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
