Profitability Comparison
Bitaxe Supra
NerdQAxe
Based on BTC price of $60,629 and current network difficulty as of Jun 6, 2026. Actual results vary.
Verdict
The NerdQAxe packs four mining chips compared to the Bitaxe Supra's single chip. More chips means more hashrate — but does it justify the price difference?
The NerdQAxe delivers roughly 4x the hashrate of the Supra, proportionally increasing your solo mining odds. However, it costs more and draws more power. The Supra remains the best value entry point, while the NerdQAxe is for enthusiasts who want maximum open-source hashrate.
Spec Deltas
Stripped to the numbers, this is how far apart the Bitaxe Supra and NerdQAxe sit on each measurable spec:
- NerdQAxe 186% more hashrate (0.7 vs 2.0 TH/s)
- Bitaxe Supra 81% better power draw (15.0 vs 80.0 W)
- Bitaxe Supra 46% better efficiency (21.4 vs 40.0 J/TH)
- Bitaxe Supra 13% better noise (35.0 vs 40.0 dB)
- Bitaxe Supra 25% better weight (0.3 vs 0.4 kg)
- NerdQAxe 433% more heat output (51.2 vs 273.0 BTU/hr)
- NerdQAxe 1% more home mining score (70.0 vs 71.0)
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.
| Bitaxe Supra | Metric | NerdQAxe |
|---|---|---|
| $89 | Upfront cost (MSRP) | $249 |
| -$0.02 | Daily net profit | -$0.14 |
| -$95 | Net after 1 year | -$299 |
| -$101 | Net after 2 years | -$349 |
| -$107 | Net after 3 years | -$399 |
| 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
Is the NerdQAxe four times more likely to find a block than the Bitaxe Supra?
Approximately yes — hashrate is directly proportional to block-finding probability. However, 4x a tiny probability is still a tiny probability. Solo mining with either device remains a lottery proposition.
Do the NerdQAxe and Bitaxe Supra use the same power supply?
No. The Bitaxe Supra uses a 5V barrel jack (5.5x2.1mm), while the NerdQAxe++ uses a 12V DC XT30 connector with a 10A PSU. They have different power requirements.
