Profitability Comparison
Bitmain Antminer S21 (200Th)
Innosilicon T3+
Based on BTC price of $79,143 and current network difficulty as of May 15, 2026. Actual results vary.
Verdict
Weighing six performance factors, the Bitmain Antminer S21 (200Th) comes out ahead — it takes 3 of 6 (efficiency, hashrate, price-performance). Where it pulls away hardest is 199% more hashrate (200.0 vs 67.0 TH/s). That said, the Innosilicon T3+ isn't beaten everywhere — it still wins power consumption and home mining score and noise level. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.

Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Bitmain Antminer S21 (200Th) | Metric | Innosilicon T3+ |
|---|---|---|
| $1,076 | Upfront cost (MSRP) | $1,200 |
| -$1.24 | Daily net profit | -$5.48 |
| -$1,527 | Net after 1 year | -$3,200 |
| -$1,978 | Net after 2 years | -$5,200 |
| -$2,429 | Net after 3 years | -$7,200 |
| 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.
