Profitability Comparison
Antminer S19k Pro
Bitaxe Gamma
Based on BTC price of $79,386 and current network difficulty as of May 15, 2026. Actual results vary.
Verdict
Based on our multi-factor analysis, the Bitaxe Gamma wins on 3 of 6 factors (efficiency, power consumption, noise level). Where it pulls away hardest is 99% better power draw (2,760.0 vs 15.0 W). That said, the Antminer S19k Pro isn't beaten everywhere — it still wins hashrate and home mining score and price-performance. Cross-check the spec deltas and ROI table above against your own electricity rate before deciding.
Spec Deltas
Here is every spec where the Antminer S19k Pro and Bitaxe Gamma actually differ, with the gap quantified:
- Antminer S19k Pro 9900% more hashrate (120.0 vs 1.2 TH/s)
- Bitaxe Gamma 99% better power draw (2,760.0 vs 15.0 W)

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.
| Antminer S19k Pro | Metric | Bitaxe Gamma |
|---|---|---|
| $2,800 | Upfront cost (MSRP) | $99 |
| -$2.24 | Daily net profit | $0.01 |
| -$3,618 | Net after 1 year | -$96 |
| -$4,435 | Net after 2 years | -$93 |
| -$5,253 | Net after 3 years | -$90 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~34.6 years to pay back at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
