Profitability Comparison
Antminer AL1
Antminer S21 Pro
Based on BTC price of $78,208 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Based on our multi-factor analysis, the Antminer S21 Pro wins on 3 of 5 factors (efficiency, hashrate, price-performance). Where it pulls away hardest is 1363% more hashrate (16.0 vs 234.0 TH/s). That said, the Antminer AL1 isn't beaten everywhere — it still wins power consumption and home mining score. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
Stripped to the numbers, this is how far apart the Antminer AL1 and Antminer S21 Pro sit on each measurable spec:
- Antminer S21 Pro 1363% more hashrate (16.0 vs 234.0 TH/s)
- Antminer AL1 4% better power draw (3,360 vs 3,510 W)
- Antminer S21 Pro 93% better efficiency (210.0 vs 15.0 J/TH)
- Antminer AL1 3% better weight (14.5 vs 15.0 kg)
- Antminer S21 Pro 4% more heat output (11,464 vs 11,976 BTU/hr)
- Antminer AL1 20% more home mining score (36.0 vs 30.0)
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 AL1 | Metric | Antminer S21 Pro |
|---|---|---|
| $10,000 | Upfront cost (MSRP) | $6,800 |
| -$7.49 | Daily net profit | -$0.00 |
| -$12,733 | Net after 1 year | -$6,801 |
| -$15,466 | Net after 2 years | -$6,802 |
| -$18,200 | Net after 3 years | -$6,803 |
| Does not pay back at current rates (negative daily profit) | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
