Profitability Comparison
Antminer S19
Antminer S19j Pro
Based on BTC price of $74,859 and current network difficulty as of Mar 17, 2026. Actual results vary.
Verdict
Two S19-era workhorses from Bitmain. The base S19 launched earlier, while the S19j Pro arrived as an optimized mid-cycle refresh targeting better efficiency.
The S19j Pro wins with better efficiency and a higher hashrate ceiling. The standard S19 can be found cheaper on the secondary market, making it appealing for low-cost electricity setups or space heating conversion.
