Profitability Comparison
Antminer KS5
Antminer KS5 Pro
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 5 (hashrate, home mining score, noise level). The standout gap is 5% more hashrate (20.0 vs 21.0 TH/s) in the Antminer KS5 Pro's favour. That said, the Antminer KS5 isn't beaten everywhere — it still wins power consumption and price-performance. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
Here is every spec where the Antminer KS5 and Antminer KS5 Pro actually differ, with the gap quantified:
- Antminer KS5 Pro 5% more hashrate (20.0 vs 21.0 TH/s)
- Antminer KS5 5% better power draw (3,000 vs 3,150 W)
- Antminer KS5 Pro 1% better noise (76.0 vs 75.0 dB)
- Antminer KS5 Pro 8% better weight (15.8 vs 14.5 kg)
- Antminer KS5 Pro 5% more heat output (10,236 vs 10,748 BTU/hr)
- Antminer KS5 Pro 24% more home mining score (29.0 vs 36.0)
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 | Metric | Antminer KS5 Pro |
|---|---|---|
| $12,000 | Upfront cost (MSRP) | $15,000 |
| -$6.48 | Daily net profit | -$6.80 |
| -$14,366 | Net after 1 year | -$17,484 |
| -$16,731 | Net after 2 years | -$19,968 |
| -$19,097 | Net after 3 years | -$22,451 |
| 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.
