Profitability Comparison
Antminer D9
Bitmain Antminer S21 XP Immersion
Based on BTC price of $64,316 and current network difficulty as of Jun 4, 2026. Actual results vary.
Verdict
Weighing six performance factors, the Bitmain Antminer S21 XP Immersion comes out ahead — it takes 5 of 6 (efficacité, hashrate, score de minage domestique, niveau sonore, rapport qualité-prix). Its biggest concrete edge: 16849% more hashrate (1.8 vs 300.0 TH/s). That said, the Antminer D9 isn't beaten everywhere — it still wins consommation électrique. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.

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 D9 | Metric | Bitmain Antminer S21 XP Immersion |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | $1,593 |
| -$6.76 | Daily net profit | -$0.99 |
| -$5,468 | Net after 1 year | -$1,954 |
| -$7,936 | Net after 2 years | -$2,316 |
| -$10,404 | Net after 3 years | -$2,678 |
| 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.
