Profitability Comparison
Bitaxe Gamma
Bitaxe Ultra
Based on BTC price of $78,083 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Our scoring model gives the nod to the Bitaxe Gamma, which leads on 3 of 4 weighted factors (efficiency, hashrate, price-performance). Where it pulls away hardest is 58% better efficiency (12.5 vs 30.0 J/TH). That said, the Bitaxe Ultra isn't beaten everywhere — it still wins noise level. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
Stripped to the numbers, this is how far apart the Bitaxe Gamma and Bitaxe Ultra sit on each measurable spec:
- Bitaxe Gamma 140% more hashrate (1.2 vs 0.5 TH/s)
- Bitaxe Gamma 58% better efficiency (12.5 vs 30.0 J/TH)
- Bitaxe Ultra 8% better noise (38.0 vs 35.0 dB)
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 Gamma | Metric | Bitaxe Ultra |
|---|---|---|
| $99 | Upfront cost (MSRP) | $79 |
| $0.01 | Daily net profit | -$0.02 |
| -$96 | Net after 1 year | -$86 |
| -$94 | Net after 2 years | -$92 |
| -$91 | Net after 3 years | -$99 |
| Takes ~38.1 years to pay back at current rates | 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 makes more money, the Bitaxe Gamma or the Bitaxe Ultra?
At the current BTC price and a $0.10/kWh electricity rate, the Bitaxe Gamma is more profitable at $0.01/day compared to $-0.02/day for the Bitaxe Ultra. Profitability depends heavily on your electricity rate — use the selector above to calculate with your actual costs.
Is the Bitaxe Gamma or the Bitaxe Ultra better for noise-sensitive spaces?
The Bitaxe Ultra is quieter at 35 dB compared to the Bitaxe Gamma at 38 dB. For home mining, lower noise levels make a significant difference in livability.
For mining at home, should I pick the Bitaxe Gamma or the Bitaxe Ultra?
Both miners score similarly on our Home Mining Score. Consider your specific constraints (noise tolerance, available power, heat needs) to decide.
How far apart are the Bitaxe Gamma and Bitaxe Ultra on J/TH?
The Bitaxe Gamma runs at 12.5 J/TH while the Bitaxe Ultra runs at 30.0 J/TH — a difference of 17.5 J/TH. Lower efficiency means less electricity per terahash of mining power, directly reducing operating costs. In relative terms that is 58% better efficiency (12.5 vs 30.0 J/TH).
