Profitability Comparison
Bitaxe Gamma
NerdAxe
Based on BTC price of $78,234 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Two mid-tier open-source solo miners. The Bitaxe Gamma pushes higher hashrate from its chip design, while the NerdAxe offers its own take on affordable solo mining.
The Gamma typically delivers more hashrate than the NerdAxe, making it the better choice for maximizing solo mining probability. The NerdAxe remains a solid alternative with its own community following.
Spec Deltas
The Bitaxe Gamma and NerdAxe 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)
- NerdAxe 20% better power draw (15.0 vs 12.0 W)
- Bitaxe Gamma 48% better efficiency (12.5 vs 24.0 J/TH)
- NerdAxe 21% better noise (38.0 vs 30.0 dB)
- NerdAxe 33% better weight (0.3 vs 0.2 kg)
- Bitaxe Gamma 25% more heat output (51.2 vs 40.9 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.
| Bitaxe Gamma | Metric | NerdAxe |
|---|---|---|
| $99 | Upfront cost (MSRP) | $69 |
| $0.01 | Daily net profit | -$0.01 |
| -$96 | Net after 1 year | -$73 |
| -$94 | Net after 2 years | -$77 |
| -$91 | Net after 3 years | -$81 |
| Takes ~37.7 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.

Frequently Asked Questions
How much more hashrate does the Gamma produce?
The Gamma achieves roughly double the hashrate of the NerdAxe, translating to proportionally better solo mining probability over time.
Are both fully open-source?
Yes. Both the Bitaxe and NerdAxe families are fully open-source hardware. Schematics, firmware, and board layouts are publicly available.
