Profitability Comparison
Antminer S19j
Bitaxe Gamma
Based on BTC price of $63,363 and current network difficulty as of Jun 8, 2026. Actual results vary.
Verdict
Weighing six performance factors, the Bitaxe Gamma comes out ahead — it takes 3 of 6 (efficacité, consommation électrique, niveau sonore). Where it pulls away hardest is 100% better power draw (3,100.0 vs 15.0 W). That said, the Antminer S19j isn't beaten everywhere — it still wins hashrate and score de minage domestique and rapport qualité-prix. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The Antminer S19j and Bitaxe Gamma diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Antminer S19j 7400% more hashrate (90.0 vs 1.2 TH/s)
- Bitaxe Gamma 100% better power draw (3,100.0 vs 15.0 W)
- Bitaxe Gamma 64% better efficacité (34.4 vs 12.5 J/TH)
- Bitaxe Gamma 49% better noise (75.0 vs 38.0 dB)
- Bitaxe Gamma 98% better weight (13.0 vs 0.3 kg)
- Antminer S19j 20559% more heat output (10,577.2 vs 51.2 BTU/hr)
- Antminer S19j 20% more score de minage domestique (84.0 vs 70.0)
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.
| Antminer S19j | Metric | Bitaxe Gamma |
|---|---|---|
| $2,000 | Upfront cost (MSRP) | $99 |
| -$4.86 | Daily net profit | -$0.00 |
| -$3,774 | Net after 1 year | -$100 |
| -$5,548 | Net after 2 years | -$100 |
| -$7,322 | Net after 3 years | -$101 |
| 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.
