Profitability Comparison
Bitaxe Gamma
Bitaxe Supra
Based on BTC price of $61,103 and current network difficulty as of Jun 6, 2026. Actual results vary.
Verdict
Two of D-Central's most popular Bitaxe solo miners face off. The Supra uses the BM1366 chip while the Gamma uses the newer BM1370, both designed for lottery-style solo Bitcoin mining.
The Gamma delivers better efficiency thanks to its newer chip, producing slightly more hashrate per watt. However, the Supra's lower price makes it an excellent entry point for solo mining. Both have similar chances of finding a block — the difference in hashrate is tiny compared to network difficulty.
Spec Deltas
Stripped to the numbers, this is how far apart the Bitaxe Gamma and Bitaxe Supra sit on each measurable spec:
- Bitaxe Gamma 71% more hashrate (1.2 vs 0.7 TH/s)
- Bitaxe Gamma 42% better efficiency (12.5 vs 21.4 J/TH)
- Bitaxe Supra 8% better noise (38.0 vs 35.0 dB)
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 Gamma | Metric | Bitaxe Supra |
|---|---|---|
| $99 | Upfront cost (MSRP) | $89 |
| -$0.00 | Daily net profit | -$0.02 |
| -$100 | Net after 1 year | -$95 |
| -$101 | Net after 2 years | -$101 |
| -$102 | Net after 3 years | -$107 |
| 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
Does the Bitaxe Gamma have a better chance of finding a block than the Supra?
Technically yes, since it has a marginally higher hashrate. But the probability difference is negligible — both produce such a tiny fraction of network hashrate that solo block finds are pure lottery events regardless.
Which Bitaxe should I buy for my first solo miner?
The Supra is the most popular starting point due to its lower price. If budget allows, the Gamma's better efficiency means slightly lower electricity costs for the same solo mining experience.
Are the Bitaxe Supra and Gamma the same physical size?
Yes, they share the same form factor and use the same accessories — cases, heatsinks, mesh stands, and 5V barrel jack power supplies are interchangeable.
