Profitability Comparison
Bitmain Antminer G2
Jasminer X4-1U
Based on BTC price of $78,165 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Weighing six performance factors, the Jasminer X4-1U comes out ahead — it takes 2 of 2 (efficiency, power consumption). Where it pulls away hardest is 92% better efficiency (5,454,545 vs 461,538 J/TH). Cross-check the spec deltas and ROI table above against your own electricity rate before deciding.
Spec Deltas
The Bitmain Antminer G2 and Jasminer X4-1U diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Jasminer X4-1U 136% more hashrate (0.0 vs 0.0 TH/s)
- Jasminer X4-1U 80% better power draw (1,200 vs 240 W)
- Jasminer X4-1U 92% better efficiency (5,454,545 vs 461,538 J/TH)
- Bitmain Antminer G2 400% more heat output (4,094 vs 819 BTU/hr)
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.
| Bitmain Antminer G2 | Metric | Jasminer X4-1U |
|---|---|---|
| — | Upfront cost (MSRP) | $209 |
| -$2.88 | Daily net profit | -$0.58 |
| -$1,051 | Net after 1 year | -$419 |
| -$2,102 | Net after 2 years | -$629 |
| -$3,154 | Net after 3 years | -$840 |
| — | 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.
