Profitability Comparison
Antminer E9 Pro
Antminer KS5 Pro
Based on BTC price of $78,124 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Antminer KS5 Pro edges it: 3 of 5 factors go its way (efficiency, hashrate, price-performance). Its biggest concrete edge: 570552% more hashrate (0.0 vs 21.0 TH/s). The Antminer E9 Pro 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
The Antminer E9 Pro and Antminer KS5 Pro diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":

- Antminer E9 Pro 11% more home mining score (40.0 vs 36.0)
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 E9 Pro | Metric | Antminer KS5 Pro |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | $15,000 |
| -$5.28 | Daily net profit | -$6.81 |
| -$4,927 | Net after 1 year | -$17,484 |
| -$6,854 | Net after 2 years | -$19,968 |
| -$8,781 | 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.
