Profitability Comparison
Antminer S19k Pro
Bitmain Antminer S23e U2H
Based on BTC price of $79,061 and current network difficulty as of May 15, 2026. Actual results vary.
Verdict
Based on our multi-factor analysis, the Bitmain Antminer S23e U2H wins on 3 of 6 factors (efficiency, hashrate, price-performance). The standout gap is 621% more hashrate (120 vs 865 TH/s) in the Bitmain Antminer S23e U2H's favour. That said, the Antminer S19k Pro isn't beaten everywhere — it still wins power consumption and 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.
Spec Deltas
The Antminer S19k Pro and Bitmain Antminer S23e U2H diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitmain Antminer S23e U2H 621% more hashrate (120 vs 865 TH/s)
- Antminer S19k Pro 68% better power draw (2,760 vs 8,650 W)

- Antminer S19k Pro 70% better weight (12.5 vs 42.0 kg)
- Bitmain Antminer S23e U2H 213% more heat output (9,417 vs 29,514 BTU/hr)
- Antminer S19k Pro 425% more home mining score (84.0 vs 16.0)
Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Antminer S19k Pro | Metric | Bitmain Antminer S23e U2H |
|---|---|---|
| $2,800 | Upfront cost (MSRP) | $19,600 |
| -$2.26 | Daily net profit | $10.71 |
| -$3,624 | Net after 1 year | -$15,691 |
| -$4,448 | Net after 2 years | -$11,781 |
| -$5,273 | Net after 3 years | -$7,872 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~5.0 years to pay back at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
