Profitability Comparison
Bitaxe Gamma
Bitaxe GT
Based on BTC price of $78,265 and current network difficulty as of May 16, 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 317% more hashrate (1.2 vs 5.0 TH/s)
- Bitaxe Gamma 80% better power draw (15.0 vs 75.0 W)
- Bitaxe Gamma 17% better efficiency (12.5 vs 15.0 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 400% more heat output (51.2 vs 255.9 BTU/hr)
- Bitaxe Gamma 9% more home mining score (70.0 vs 64.0)
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 | $0.00 |
| -$96 | Net after 1 year | -$499 |
| -$94 | Net after 2 years | -$499 |
| -$91 | Net after 3 years | -$499 |
| Takes ~37.6 years to pay back at current rates | Payback period | Takes ~16,841.5 years to pay back at current rates |
At the default rate, the Bitaxe Gamma reaches break-even first — but plug in your own electricity cost above, since payback shifts sharply with it.
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
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.
