Profitability Comparison
Innosilicon S11 SiaMaster
StrongU STU-U2
Based on BTC price of $78,244 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Weighing six performance factors, the StrongU STU-U2 comes out ahead — it takes 3 of 5 (efficacité, hashrate, rapport qualité-prix). Where it pulls away hardest is 63% more hashrate (4.3 vs 7.0 TH/s). That said, the Innosilicon S11 SiaMaster isn't beaten everywhere — it still wins consommation électrique and score de minage domestique. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The Innosilicon S11 SiaMaster and StrongU STU-U2 diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- StrongU STU-U2 63% more hashrate (4.3 vs 7.0 TH/s)
- Innosilicon S11 SiaMaster 16% better power draw (1,350 vs 1,600 W)
- StrongU STU-U2 27% better efficacité (314 vs 229 J/TH)
- Innosilicon S11 SiaMaster 43% better weight (3,700 vs 6,500 kg)
- StrongU STU-U2 19% more heat output (4,606 vs 5,459 BTU/hr)
- Innosilicon S11 SiaMaster 11% more score de minage domestique (31.0 vs 28.0)
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.
| Innosilicon S11 SiaMaster | Metric | StrongU STU-U2 |
|---|---|---|
| $2,000 | Upfront cost (MSRP) | $499 |
| -$3.09 | Daily net profit | -$3.59 |
| -$3,126 | Net after 1 year | -$1,809 |
| -$4,252 | Net after 2 years | -$3,118 |
| -$5,378 | Net after 3 years | -$4,428 |
| 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.
