Profitability Comparison
Antminer AL1
Antminer S21+
Based on BTC price of $65,075 and current network difficulty as of Jun 17, 2026. Actual results vary.
Verdict
Weighing six performance factors, the Antminer S21+ comes out ahead — it takes 3 of 4 (efficacité, hashrate, rapport qualité-prix). The standout gap is 1250% more hashrate (16.0 vs 216.0 TH/s) in the Antminer S21+'s favour. The Antminer AL1 claws back ground on consommation électrique. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The Antminer AL1 and Antminer S21+ diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Antminer S21+ 1250% more hashrate (16.0 vs 216.0 TH/s)
- Antminer AL1 6% better power draw (3,360 vs 3,564 W)
- Antminer S21+ 92% better efficacité (210.0 vs 16.5 J/TH)
- Antminer AL1 3% better weight (14.5 vs 15.0 kg)
- Antminer S21+ 6% more heat output (11,464 vs 12,160 BTU/hr)
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.
| Antminer AL1 | Metric | Antminer S21+ |
|---|---|---|
| $10,000 | Upfront cost (MSRP) | $6,500 |
| -$7.54 | Daily net profit | -$1.48 |
| -$12,752 | Net after 1 year | -$7,040 |
| -$15,504 | Net after 2 years | -$7,581 |
| -$18,256 | Net after 3 years | -$8,121 |
| 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.
