Based on BTC price of $63,093 and current network difficulty as of Jun 4, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Bitmain Antminer Z15 Pro edges it: 3 of 5 factors go its way (efficacité, hashrate, rapport qualité-prix). The standout gap is 100% more hashrate (420 vs 840 TH/s) in the Bitmain Antminer Z15 Pro's favour. The Bitmain Antminer Z15 holds the edge in consommation électrique and score de minage domestique. Cross-check the spec deltas and operating-cost table above against your own electricity rate before deciding.
Spec Deltas
Here is every spec where the Bitmain Antminer Z15 and Bitmain Antminer Z15 Pro actually differ, with the gap quantified:
- Bitmain Antminer Z15 Pro 100% more hashrate (420 vs 840 TH/s)
- Bitmain Antminer Z15 46% better power draw (1,510 vs 2,780 W)
- Bitmain Antminer Z15 Pro 8% better efficacité (3.6 vs 3.3 J/TH)
- Bitmain Antminer Z15 47% better weight (9.0 vs 17.0 kg)
- Bitmain Antminer Z15 Pro 84% more heat output (5,152 vs 9,485 BTU/hr)
- Bitmain Antminer Z15 27% more score de minage domestique (28.0 vs 22.0)
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 Z15 | Metric | Bitmain Antminer Z15 Pro |
|---|---|---|
| $998 | Upfront cost (MSRP) | $1,800 |
| $8.36 | Daily net profit | $17.30 |
| +$2,055 | Net after 1 year | +$4,516 |
| +$5,108 | Net after 2 years | +$10,832 |
| +$8,161 | Net after 3 years | +$17,149 |
| Pays for itself in ~4 months at current rates | Payback period | Pays for itself in ~3 months at current rates |
At the default rate, the Bitmain Antminer Z15 Pro reaches break-even first — but plug in your own electricity cost above, since payback shifts sharply with it.
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
