Profitability Comparison
Antminer K7
Bitmain Antminer S23e U2H
Based on BTC price of $64,340 and current network difficulty as of Jun 4, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Bitmain Antminer S23e U2H edges it: 3 of 6 factors go its way (efficacité, hashrate, rapport qualité-prix). Where it pulls away hardest is 1262% more hashrate (63.5 vs 865.0 TH/s). That said, the Antminer K7 isn't beaten everywhere — it still wins consommation électrique and score de minage domestique and niveau sonore. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
