Profitability Comparison
Bitmain Antminer B3 (1Kh)
Antminer E9 Pro
Based on BTC price of $63,873 and current network difficulty as of Jun 4, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Antminer E9 Pro edges it: 4 of 5 factors go its way (efficacité, hashrate, score de minage domestique, niveau sonore). Where it pulls away hardest is 367999900% more hashrate (0.0 vs 0.0 TH/s). The Bitmain Antminer B3 (1Kh) claws back ground on consommation électrique. Cross-check the spec deltas and operating-cost table above against your own electricity rate before deciding.
Spec Deltas
The Bitmain Antminer B3 (1Kh) and Antminer E9 Pro diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Antminer E9 Pro 367999900% more hashrate (0.0 vs 0.0 TH/s)
- Bitmain Antminer B3 (1Kh) 83% better power draw (380 vs 2,200 W)
- Antminer E9 Pro 100% better efficacité (380,000,000,000 vs 597,826 J/TH)
- Antminer E9 Pro 479% more heat output (1,297 vs 7,506 BTU/hr)
- Antminer E9 Pro 18% more score de minage domestique (34.0 vs 40.0)
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.
| Bitmain Antminer B3 (1Kh) | Metric | Antminer E9 Pro |
|---|---|---|
| — | Upfront cost (MSRP) | $3,000 |
| -$0.91 | Daily net profit | -$5.28 |
| -$333 | Net after 1 year | -$4,927 |
| -$666 | Net after 2 years | -$6,854 |
| -$999 | Net after 3 years | -$8,781 |
| — | 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.
