Profitability Comparison
NerdQAxe
NerdQAxe++
Based on BTC price of $77,848 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
The NerdQAxe and its upgraded NerdQAxe++ variant. Both are quad-chip open-source miners, but the ++ revision brings performance improvements.
The NerdQAxe++ delivers improved hashrate and efficiency over the original NerdQAxe. If buying new, the ++ is the obvious choice. Existing NerdQAxe owners still have a capable solo mining device.
Spec Deltas
The NerdQAxe and NerdQAxe++ diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- NerdQAxe++ 100% more hashrate (2.0 vs 4.0 TH/s)
- NerdQAxe 33% better power draw (80.0 vs 120.0 W)
- NerdQAxe++ 25% better efficiency (40.0 vs 30.0 J/TH)
- NerdQAxe 5% better noise (40.0 vs 42.0 dB)
- NerdQAxe 20% better weight (0.4 vs 0.5 kg)
- NerdQAxe++ 50% more heat output (273 vs 409 BTU/hr)
- NerdQAxe 22% more home mining score (71.0 vs 58.0)
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.
| NerdQAxe | Metric | NerdQAxe++ |
|---|---|---|
| $249 | Upfront cost (MSRP) | $349 |
| -$0.12 | Daily net profit | -$0.14 |
| -$293 | Net after 1 year | -$402 |
| -$337 | Net after 2 years | -$455 |
| -$381 | 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
What changed in the ++ version?
The NerdQAxe++ features an improved board design with better power delivery and cooling, resulting in higher stable hashrate from the same chip count.
Are accessories compatible between the two?
The form factor is similar but not always identical. Check compatibility before purchasing cases or mounts designed for the original NerdQAxe.
