Profitability Comparison
IceRiver KS3L
Thewindminer K9
Based on BTC price of $78,147 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Thewindminer K9 edges it: 3 of 6 factors go its way (efficacité, hashrate, rapport qualité-prix). Where it pulls away hardest is 106% more hashrate (5.0 vs 10.3 TH/s). That said, the IceRiver KS3L 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.
