- Antminer S19 Pro 7% better power draw (3,250 vs 3,498 W)
- Bitmain Antminer S23 63% better efficiency (29.6 vs 11.0 J/TH)
- Antminer S19 Pro 1% better weight (14.4 vs 14.5 kg)
- Bitmain Antminer S23 8% more heat output (11,089 vs 11,935 BTU/hr)
- Antminer S19 Pro 133% more home mining score (84.0 vs 36.0)
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 S19 Pro | Metric | Bitmain Antminer S23 |
|---|---|---|
| $2,500 | Upfront cost (MSRP) | $4,999 |
| -$3.84 | Daily net profit | $3.05 |
| -$3,902 | Net after 1 year | -$3,885 |
| -$5,303 | Net after 2 years | -$2,770 |
| -$6,705 | Net after 3 years | -$1,656 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~4.5 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.
