Profitability Comparison
Bitaxe Supra
Bitaxe Ultra
Based on BTC price of $61,154 and current network difficulty as of Jun 6, 2026. Actual results vary.
Verdict
The entry-level Supra versus the mid-tier Ultra. Both use the same 5V power system but target different hashrate levels.
The Ultra delivers more hashrate than the Supra at a moderate price increase. Both share the same accessories and form factor. For existing buyers, the Gamma has replaced the Ultra as the recommended mid-tier option.
Spec Deltas
Stripped to the numbers, this is how far apart the Bitaxe Supra and Bitaxe Ultra sit on each measurable spec:
- Bitaxe Supra 40% more hashrate (0.7 vs 0.5 TH/s)
- Bitaxe Supra 29% better efficiency (21.4 vs 30.0 J/TH)
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 Supra | Metric | Bitaxe Ultra |
|---|---|---|
| $89 | Upfront cost (MSRP) | $79 |
| -$0.02 | Daily net profit | -$0.02 |
| -$95 | Net after 1 year | -$87 |
| -$101 | Net after 2 years | -$95 |
| -$107 | Net after 3 years | -$103 |
| 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.
