Profitability Comparison
Innosilicon A9 ZMaster
Bitmain Antminer Z9 Mini
Based on BTC price of $62,822 and current network difficulty as of Jun 4, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Innosilicon A9 ZMaster edges it: 2 of 4 factors go its way (efficacité, hashrate). Its biggest concrete edge: 400% more hashrate (50.0 vs 10.0 TH/s). That said, the Bitmain Antminer Z9 Mini isn't beaten everywhere — it still wins consommation électrique and score de minage domestique. Cross-check the spec deltas and operating-cost table above against your own electricity rate before deciding.

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.
| Innosilicon A9 ZMaster | Metric | Bitmain Antminer Z9 Mini |
|---|---|---|
| — | Upfront cost (MSRP) | $150 |
| -$0.07 | Daily net profit | -$0.44 |
| -$24 | Net after 1 year | -$309 |
| -$49 | Net after 2 years | -$468 |
| -$73 | Net after 3 years | -$627 |
| — | 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.
