Profitability Comparison
Bitaxe Gamma
Bitaxe GT
Based on BTC price of $62,524 and current network difficulty as of Jul 14, 2026. Actual results vary.
Verdict
Mid-range versus high-end in the single-chip Bitaxe lineup. The Gamma uses a proven ASIC chip while the GT employs a newer, more powerful one.
The GT wins on raw hashrate thanks to its newer chip technology. The Gamma remains popular for its balance of performance and 5V simplicity. Power delivery is the practical differentiator — 5V barrel jack versus 12V XT30.
Spec Deltas
The Bitaxe Gamma and Bitaxe GT diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitaxe GT 79% more hashrate (1.2 vs 2.2 TH/s)
- Bitaxe Gamma 58% better power draw (18.0 vs 43.0 W)
- Bitaxe Gamma 25% better efficacité (15.0 vs 20.0 J/TH)
- Bitaxe Gamma 10% better noise (38.0 vs 42.0 dB)
- Bitaxe Gamma 25% better weight (0.3 vs 0.4 kg)
- Bitaxe GT 139% more heat output (61.4 vs 146.7 BTU/hr)
- Bitaxe Gamma 12% more score de minage domestique (100.0 vs 89.0)
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 Gamma | Metric | Bitaxe GT |
|---|---|---|
| $99 | Upfront cost (MSRP) | $499 |
| -$0.01 | Daily net profit | -$0.04 |
| -$101 | Net after 1 year | -$512 |
| -$103 | Net after 2 years | -$526 |
| -$106 | Net after 3 years | -$539 |
| 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.

Foire aux questions
Can I upgrade from a Gamma to a GT?
They are separate units. You can run both simultaneously on the same pool or point them at different pools for diversification.
Which has better availability?
Both are stocked by D-Central. The Gamma has been available longer and has a wider accessory ecosystem. The GT is newer but accessories are catching up.
