Profitability Comparison
Antminer E9 Pro
Bitmain Antminer R4
Based on BTC price of $79,287 and current network difficulty as of May 15, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Bitmain Antminer R4 edges it: 3 of 5 factors go its way (efficiency, hashrate, power consumption). Where it pulls away hardest is 100% better efficiency (597,826.1 vs 97.1 J/TH). The Antminer E9 Pro holds the edge in home mining score and noise level. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
