Profitability Comparison
Bitmain Antminer L11 Hyd 2U (35Gh)
Bitmain Antminer L11 Pro (21Gh)
Based on BTC price of $78,217 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Weighing six performance factors, the Bitmain Antminer L11 Hyd 2U (35Gh) comes out ahead — it takes 4 of 6 (efficacité, hashrate, score de minage domestique, niveau sonore). The standout gap is 67% more hashrate (0.0 vs 0.0 TH/s) in the Bitmain Antminer L11 Hyd 2U (35Gh)'s favour. That said, the Bitmain Antminer L11 Pro (21Gh) isn't beaten everywhere — it still wins consommation électrique and rapport qualité-prix. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
