Profitability Comparison
NerdOctaxe Gamma
NerdQAxe++
Based on BTC price of $62,502 and current network difficulty as of Jul 14, 2026. Actual results vary.
Verdict
The quad-chip NerdQAxe++ versus the eight-chip NerdOctaxe Gamma. Both push the boundaries of open-source mining, but at very different scales.
The NerdOctaxe Gamma is the more powerful device with double the chip count. The NerdQAxe++ is more affordable and uses less power. For maximum open-source hashrate, the Octaxe wins; for a balanced build, the QAxe++ is excellent.
Spec Deltas
The NerdOctaxe Gamma and NerdQAxe++ diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- NerdOctaxe Gamma 67% more hashrate (8.0 vs 4.8 TH/s)
- NerdQAxe++ 60% better power draw (200.0 vs 80.0 W)
- NerdQAxe++ 33% better efficacité (25.0 vs 16.7 J/TH)
- NerdQAxe++ 7% better noise (45.0 vs 42.0 dB)
- NerdQAxe++ 38% better weight (0.8 vs 0.5 kg)
- NerdOctaxe Gamma 150% more heat output (682 vs 273 BTU/hr)
- NerdQAxe++ 14% more score de minage domestique (78.0 vs 89.0)
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.
| NerdOctaxe Gamma | Metric | NerdQAxe++ |
|---|---|---|
| $599 | Upfront cost (MSRP) | $349 |
| -$0.23 | Daily net profit | -$0.04 |
| -$684 | Net after 1 year | -$365 |
| -$769 | Net after 2 years | -$381 |
| -$854 | Net after 3 years | -$397 |
| 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.

Foire aux questions
What power supply does the NerdOctaxe Gamma need?
The NerdOctaxe Gamma requires a 12V DC XT60 connector with an 18-20A power supply — significantly more than the NerdQAxe++'s 12V XT30 at 10A.
Is the NerdOctaxe Gamma suitable for home use?
Yes, but it draws more power and produces more heat than the NerdQAxe++. Ensure adequate ventilation and a suitable power circuit.
