Profitability Comparison
Bitmain Antminer S21e XP Hyd 3U
Bitmain Antminer S23
Based on BTC price of $78,175 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Bitmain Antminer S21e XP Hyd 3U edges it: 4 of 6 factors go its way (hashrate, score de minage domestique, niveau sonore, rapport qualité-prix). The standout gap is 170% more hashrate (860 vs 318 TH/s) in the Bitmain Antminer S21e XP Hyd 3U's favour. The Bitmain Antminer S23 holds the edge in efficacité and consommation électrique. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The Bitmain Antminer S21e XP Hyd 3U and Bitmain Antminer S23 diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitmain Antminer S21e XP Hyd 3U 170% more hashrate (860 vs 318 TH/s)
- Bitmain Antminer S23 69% better power draw (11,180 vs 3,498 W)
- Bitmain Antminer S23 15% better efficacité (13.0 vs 11.0 J/TH)
- Bitmain Antminer S21e XP Hyd 3U 33% better noise (50.0 vs 75.0 dB)
- Bitmain Antminer S21e XP Hyd 3U 220% more heat output (38,146 vs 11,935 BTU/hr)
- Bitmain Antminer S21e XP Hyd 3U 22% more score de minage domestique (44.0 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.
| Bitmain Antminer S21e XP Hyd 3U | Metric | Bitmain Antminer S23 |
|---|---|---|
| $10,899 | Upfront cost (MSRP) | $4,999 |
| $4.11 | Daily net profit | $3.04 |
| -$9,400 | Net after 1 year | -$3,888 |
| -$7,901 | Net after 2 years | -$2,776 |
| -$6,403 | Net after 3 years | -$1,665 |
| Takes ~7.3 years to pay back at current rates | Payback period | Takes ~4.5 years to pay back at current rates |
At the default rate, the Bitmain Antminer S23 reaches break-even first — but plug in your own electricity cost above, since payback shifts sharply with it.
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
