Profitability Comparison
Antminer D7
Bitmain S19k Pro
Based on BTC price of $79,088 and current network difficulty as of May 15, 2026. Actual results vary.
Verdict
Our scoring model gives the nod to the Bitmain S19k Pro, which leads on 4 of 5 weighted factors (efficiency, hashrate, power consumption, price-performance). The standout gap is 99% better efficiency (2,447.9 vs 23.0 J/TH) in the Bitmain S19k Pro's favour. That said, the Antminer D7 isn't beaten everywhere — it still wins noise level. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
