Profitability Comparison
Bitaxe Hex
NerdQAxe++
Based on BTC price of $78,253 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Multi-chip open-source showdown. The six-chip Bitaxe Hex versus the quad-chip NerdQAxe++. More chips versus refined architecture.
The Bitaxe Hex produces more total hashrate from its six chips versus the NerdQAxe++'s four. The NerdQAxe++ may offer better value per chip. Both are serious open-source solo mining devices.
Spec Deltas
Here is every spec where the Bitaxe Hex and NerdQAxe++ actually differ, with the gap quantified:
- NerdQAxe++ 33% more hashrate (3.0 vs 4.0 TH/s)
- Bitaxe Hex 25% better power draw (90.0 vs 120.0 W)
- NerdQAxe++ 7% better noise (45.0 vs 42.0 dB)
- NerdQAxe++ 33% more heat output (307 vs 409 BTU/hr)
- Bitaxe Hex 10% more home mining score (64.0 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.
| Bitaxe Hex | Metric | NerdQAxe++ |
|---|---|---|
| $399 | Upfront cost (MSRP) | $349 |
| -$0.11 | Daily net profit | -$0.14 |
| -$438 | Net after 1 year | -$402 |
| -$478 | Net after 2 years | -$454 |
| -$517 | 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 costs more to run?
The Bitaxe Hex draws more power due to its six chips. Both require 12V DC power — the Hex via XT30, the NerdQAxe++ also via XT30.
Can I run both on the same mining pool?
Absolutely. Running multiple devices on the same pool combines their hashrate for better solo mining probability.
