Profitability Comparison
Innosilicon S11 SiaMaster
Obelisk SC1 Dual
Based on BTC price of $78,257 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Innosilicon S11 SiaMaster edges it: 2 of 3 factors go its way (efficiency, hashrate). Where it pulls away hardest is 291% more hashrate (4.3 vs 1.1 TH/s). The Obelisk SC1 Dual claws back ground on power consumption. Cross-check the spec deltas and ROI table above against your own electricity rate before deciding.
Spec Deltas
The Innosilicon S11 SiaMaster and Obelisk SC1 Dual diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Innosilicon S11 SiaMaster 291% more hashrate (4.3 vs 1.1 TH/s)
- Obelisk SC1 Dual 33% better power draw (1,350 vs 900 W)
- Innosilicon S11 SiaMaster 62% better efficiency (314 vs 818 J/TH)
- Innosilicon S11 SiaMaster 50% more heat output (4,606 vs 3,071 BTU/hr)
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 | Obelisk SC1 Dual |
|---|---|---|
| $2,000 | Upfront cost (MSRP) | — |
| -$3.09 | Daily net profit | -$2.12 |
| -$3,126 | Net after 1 year | -$774 |
| -$4,252 | Net after 2 years | -$1,548 |
| -$5,378 | Net after 3 years | -$2,322 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
