Profitability Comparison
Goldshell KD2
Goldshell KD6-SE
Based on BTC price of $78,217 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Weighing six performance factors, the Goldshell KD6-SE comes out ahead — it takes 3 of 5 (efficiency, hashrate, price-performance). Its biggest concrete edge: 322% more hashrate (6.0 vs 25.3 TH/s). That said, the Goldshell KD2 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.
Spec Deltas
The Goldshell KD2 and Goldshell KD6-SE diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":

- Goldshell KD2 8% more home mining score (28.0 vs 26.0)
Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Goldshell KD2 | Metric | Goldshell KD6-SE |
|---|---|---|
| $828 | Upfront cost (MSRP) | $1,016 |
| -$1.78 | Daily net profit | -$4.61 |
| -$1,476 | Net after 1 year | -$2,698 |
| -$2,125 | Net after 2 years | -$4,381 |
| -$2,773 | Net after 3 years | -$6,063 |
| 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.
