Profitability Comparison
Bitaxe Hex
NerdQAxe
Based on BTC price of $78,252 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Two multi-chip open-source miners compared. The Bitaxe Hex (six chips) versus the NerdQAxe (four chips). Both push the boundaries of open-source mining hardware.
The Bitaxe Hex packs more chips (six vs four) for higher total hashrate, but efficiency depends on chip generation. Both represent the high end of open-source mining. Choose based on availability, price, and your preferred ecosystem.

- NerdQAxe 11% more home mining score (64.0 vs 71.0)
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 Hex | Metric | NerdQAxe |
|---|---|---|
| $399 | Upfront cost (MSRP) | $249 |
| -$0.11 | Daily net profit | -$0.12 |
| -$438 | Net after 1 year | -$293 |
| -$478 | Net after 2 years | -$337 |
| -$517 | Net after 3 years | -$380 |
| 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.
