Profitability Comparison
Antminer KS5 Pro
IceRiver KS2
Based on BTC price of $78,139 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Weighing six performance factors, the Antminer KS5 Pro comes out ahead — it takes 3 of 6 (efficiency, hashrate, price-performance). Its biggest concrete edge: 950% more hashrate (21.0 vs 2.0 TH/s). The IceRiver KS2 holds the edge in power consumption and home mining score and noise level. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.

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.
| Antminer KS5 Pro | Metric | IceRiver KS2 |
|---|---|---|
| $15,000 | Upfront cost (MSRP) | $5,000 |
| -$6.80 | Daily net profit | -$2.81 |
| -$17,484 | Net after 1 year | -$6,025 |
| -$19,968 | Net after 2 years | -$7,050 |
| -$22,451 | Net after 3 years | -$8,075 |
| 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.
