Profitability Comparison
Antminer KS5 Pro
Iceriver KS3
Based on BTC price of $78,139 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Based on our multi-factor analysis, the Antminer KS5 Pro wins on 3 of 4 factors (efficiency, hashrate, power consumption). Its biggest concrete edge: 63% better efficiency (150 vs 400 J/TH). The Iceriver KS3 holds the edge in price-performance. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
Stripped to the numbers, this is how far apart the Antminer KS5 Pro and Iceriver KS3 sit on each measurable spec:
- Antminer KS5 Pro 163% more hashrate (21.0 vs 8.0 TH/s)
- Antminer KS5 Pro 2% better power draw (3,150 vs 3,200 W)
- Antminer KS5 Pro 63% better efficiency (150 vs 400 J/TH)
- Iceriver KS3 7% better weight (14.5 vs 13.5 kg)
- Iceriver KS3 2% more heat output (10,748 vs 10,918 BTU/hr)
Cost & ROI Over Time
Hardware cost is only half the story — here is how each miner's upfront price plays out against cumulative profit at a $0.10/kWh rate.
| Antminer KS5 Pro | Metric | Iceriver KS3 |
|---|---|---|
| $15,000 | Upfront cost (MSRP) | $730 |
| -$6.80 | Daily net profit | -$7.39 |
| -$17,484 | Net after 1 year | -$3,428 |
| -$19,968 | Net after 2 years | -$6,126 |
| -$22,451 | Net after 3 years | -$8,825 |
| 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.
