Profitability Comparison
Bitaxe Gamma
PiAxe
Based on BTC price of $78,245 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Weighing six performance factors, the Bitaxe Gamma comes out ahead — it takes 3 of 4 (efficacité, hashrate, rapport qualité-prix). The standout gap is 58% better efficacité (12.5 vs 30.0 J/TH) in the Bitaxe Gamma's favour. The PiAxe holds the edge in niveau sonore. Cross-check the spec deltas and ROI table above against your own electricity rate before deciding.
Spec Deltas
The Bitaxe Gamma and PiAxe diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitaxe Gamma 140% more hashrate (1.2 vs 0.5 TH/s)
- Bitaxe Gamma 58% better efficacité (12.5 vs 30.0 J/TH)
- PiAxe 21% better noise (38.0 vs 30.0 dB)
- PiAxe 33% better weight (0.3 vs 0.2 kg)
Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Bitaxe Gamma | Metric | PiAxe |
|---|---|---|
| $99 | Upfront cost (MSRP) | $79 |
| $0.01 | Daily net profit | -$0.02 |
| -$96 | Net after 1 year | -$86 |
| -$94 | Net after 2 years | -$92 |
| -$91 | Net after 3 years | -$99 |
| Takes ~37.6 years to pay back at current rates | 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.

Which is better for home mining, the Bitaxe Gamma or PiAxe?
Both miners score similarly on our Home Mining Score. Consider your specific constraints (noise tolerance, available power, heat needs) to decide.
Bitaxe Gamma vs PiAxe: how much does the efficiency gap matter?
The Bitaxe Gamma runs at 12.5 J/TH while the PiAxe runs at 30.0 J/TH — a difference of 17.5 J/TH. Lower efficiency means less electricity per terahash of mining power, directly reducing operating costs. In relative terms that is 58% better efficacité (12.5 vs 30.0 J/TH).
