Profitability Comparison
Innosilicon T3 50T
MicroBT Whatsminer M21S
Based on BTC price of $78,190 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the MicroBT Whatsminer M21S edges it: 2 of 3 factors go its way (efficacité, hashrate). The standout gap is 12% more hashrate (50.0 vs 56.0 TH/s) in the MicroBT Whatsminer M21S's favour. That said, the Innosilicon T3 50T isn't beaten everywhere — it still wins consommation électrique. Cross-check the spec deltas and ROI table above against your own electricity rate before deciding.
Spec Deltas
The Innosilicon T3 50T and MicroBT Whatsminer M21S diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- MicroBT Whatsminer M21S 12% more hashrate (50.0 vs 56.0 TH/s)
- Innosilicon T3 50T 8% better power draw (3,100 vs 3,360 W)
- MicroBT Whatsminer M21S 3% better efficacité (62.0 vs 60.0 J/TH)
- Innosilicon T3 50T 20% better weight (10,000 vs 12,500 kg)
- MicroBT Whatsminer M21S 8% more heat output (10,577 vs 11,464 BTU/hr)
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 T3 50T | Metric | MicroBT Whatsminer M21S |
|---|---|---|
| — | Upfront cost (MSRP) | $650 |
| -$5.64 | Daily net profit | -$6.05 |
| -$2,059 | Net after 1 year | -$2,858 |
| -$4,118 | Net after 2 years | -$5,066 |
| -$6,177 | Net after 3 years | -$7,274 |
| — | 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.
