Profitability Comparison
Bitmain KAS KS7
Iceriver KS2
Based on BTC price of $78,153 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Bitmain KAS KS7 edges it: 3 of 5 factors go its way (efficiency, hashrate, price-performance). Where it pulls away hardest is 1900% more hashrate (40.0 vs 2.0 TH/s). The Iceriver KS2 claws back ground on 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

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.
| Bitmain KAS KS7 | Metric | Iceriver KS2 |
|---|---|---|
| $1,590 | Upfront cost (MSRP) | $399 |
| -$5.95 | Daily net profit | -$2.81 |
| -$3,763 | Net after 1 year | -$1,424 |
| -$5,936 | Net after 2 years | -$2,449 |
| -$8,109 | Net after 3 years | -$3,474 |
| 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.
