Profitability Comparison
Antminer S21+
Ebang Ebit E9.2
Based on BTC price of $79,097 and current network difficulty as of May 15, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Antminer S21+ edges it: 3 of 5 factors go its way (efficiency, hashrate, noise level). Where it pulls away hardest is 1700% more hashrate (216.0 vs 12.0 TH/s). The Ebang Ebit E9.2 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 S21+ and Ebang Ebit E9.2 diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Antminer S21+ 1700% more hashrate (216.0 vs 12.0 TH/s)
- Ebang Ebit E9.2 63% better power draw (3,564 vs 1,320 W)
- Antminer S21+ 85% better efficiency (16.5 vs 110.0 J/TH)
- Antminer S21+ 100% better weight (15.0 vs 4,700.0 kg)
- Antminer S21+ 170% more heat output (12,160 vs 4,504 BTU/hr)
- Ebang Ebit E9.2 3% more home mining score (30.0 vs 31.0)
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 S21+ | Metric | Ebang Ebit E9.2 |
|---|---|---|
| $6,500 | Upfront cost (MSRP) | — |
| -$0.69 | Daily net profit | -$2.73 |
| -$6,752 | Net after 1 year | -$997 |
| -$7,005 | Net after 2 years | -$1,994 |
| -$7,257 | Net after 3 years | -$2,991 |
| Does not pay back at current rates (negative daily profit) | Payback period | — |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
