Profitability Comparison
Obelisk SC1
Goldshell SC5 Pro (11Th)
Based on BTC price of $78,178 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Goldshell SC5 Pro (11Th) edges it: 2 of 4 factors go its way (efficiency, hashrate). Its biggest concrete edge: 1900% more hashrate (0.6 vs 11.0 TH/s). That said, the Obelisk SC1 isn't beaten everywhere — it still wins power consumption and home mining score. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.

- Obelisk SC1 55% more home mining score (34.0 vs 22.0)
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.
| Obelisk SC1 | Metric | Goldshell SC5 Pro (11Th) |
|---|---|---|
| — | Upfront cost (MSRP) | $430 |
| -$1.18 | Daily net profit | -$6.37 |
| -$431 | Net after 1 year | -$2,756 |
| -$862 | Net after 2 years | -$5,082 |
| -$1,292 | Net after 3 years | -$7,408 |
| — | 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.
