Spec Deltas
The Bitmain Antminer G2 and Jasminer X4 diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Jasminer X4 1036% more hashrate (0.0 vs 0.0 TH/s)
- Jasminer X4 91% better efficiency (5,454,545 vs 480,000 J/TH)
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.
| Bitmain Antminer G2 | Metric | Jasminer X4 |
|---|---|---|
| — | Upfront cost (MSRP) | $999 |
| -$2.88 | Daily net profit | -$2.88 |
| -$1,051 | Net after 1 year | -$2,050 |
| -$2,102 | Net after 2 years | -$3,101 |
| -$3,154 | Net after 3 years | -$4,153 |
| — | 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.
