Profitability Comparison
Antminer Loki Edition (S9)
PiAxe
Based on BTC price of $79,091 and current network difficulty as of May 15, 2026. Actual results vary.
Verdict
Weighing six performance factors, the PiAxe comes out ahead — it takes 4 of 6 (efficiency, power consumption, home mining score, noise level). Its biggest concrete edge: 99% better power draw (1,350.0 vs 15.0 W). The Antminer Loki Edition (S9) holds the edge in hashrate and price-performance. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The Antminer Loki Edition (S9) and PiAxe diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":

- PiAxe 99% better power draw (1,350.0 vs 15.0 W)
- PiAxe 69% better efficiency (96.4 vs 30.0 J/TH)
- PiAxe 45% better noise (55.0 vs 30.0 dB)
- PiAxe 97% better weight (6.0 vs 0.2 kg)
- Antminer Loki Edition (S9) 8896% more heat output (4,606.2 vs 51.2 BTU/hr)
- PiAxe 19% more home mining score (59.0 vs 70.0)
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.
| Antminer Loki Edition (S9) | Metric | PiAxe |
|---|---|---|
| $349 | Upfront cost (MSRP) | $79 |
| -$2.73 | Daily net profit | -$0.02 |
| -$1,346 | Net after 1 year | -$85 |
| -$2,342 | Net after 2 years | -$92 |
| -$3,339 | Net after 3 years | -$98 |
| 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.
