Profitability Comparison
Bitaxe GT
NerdQAxe++
Based on BTC price of $77,884 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Bitaxe's highest-hashrate single chip versus the NerdQAxe++'s quad-chip approach. Two philosophies for serious open-source solo mining.
The NerdQAxe++ produces more total hashrate from its four chips, but the Bitaxe GT achieves impressive performance from a single chip. The GT is simpler to set up and power, while the QAxe++ maximizes hashrate per device.
Spec Deltas
Stripped to the numbers, this is how far apart the Bitaxe GT and NerdQAxe++ sit on each measurable spec:
- Bitaxe GT 25% more hashrate (5.0 vs 4.0 TH/s)
- Bitaxe GT 38% better power draw (75.0 vs 120.0 W)
- Bitaxe GT 50% better efficiency (15.0 vs 30.0 J/TH)
- Bitaxe GT 20% better weight (0.4 vs 0.5 kg)
- NerdQAxe++ 60% more heat output (256 vs 409 BTU/hr)
- Bitaxe GT 10% more home mining score (64.0 vs 58.0)
Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Bitaxe GT | Metric | NerdQAxe++ |
|---|---|---|
| $499 | Upfront cost (MSRP) | $349 |
| -$0.00 | Daily net profit | -$0.14 |
| -$499 | Net after 1 year | -$402 |
| -$500 | Net after 2 years | -$455 |
| -$500 | Net after 3 years | -$507 |
| 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.

Frequently Asked Questions
Which uses less power?
The single-chip Bitaxe GT draws less total power. Both require 12V DC, but the GT's XT30 connector and lower wattage make it easier to power.
Which is easier to set up?
The Bitaxe GT — single chip, single firmware, simple AxeOS web interface. The NerdQAxe++ is straightforward too but has more components.
