- Bitmain Antminer S23e U2H 2989% more hashrate (28.0 vs 865.0 TH/s)
- Bitmain Antminer S15 (28Th) 82% better power draw (1,596 vs 8,650 W)
- Bitmain Antminer S23e U2H 82% better efficacité (57.0 vs 10.0 J/TH)
- Bitmain Antminer S23e U2H 99% better weight (7,000.0 vs 42.0 kg)
- Bitmain Antminer S23e U2H 442% more heat output (5,446 vs 29,514 BTU/hr)
- Bitmain Antminer S15 (28Th) 75% more score de minage domestique (28.0 vs 16.0)
Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Bitmain Antminer S15 (28Th) | Metric | Bitmain Antminer S23e U2H |
|---|---|---|
| $5,599 | Upfront cost (MSRP) | $19,600 |
| -$2.82 | Daily net profit | $10.32 |
| -$6,630 | Net after 1 year | -$15,835 |
| -$7,661 | Net after 2 years | -$12,070 |
| -$8,692 | Net after 3 years | -$8,305 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~5.2 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.
