Profitability Comparison
Bitmain S19k Pro
Whatsminer M30S+
Based on BTC price of $78,208 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Our scoring model gives the nod to the Bitmain S19k Pro, which leads on 4 of 4 weighted factors (efficacité, hashrate, consommation électrique, rapport qualité-prix). Where it pulls away hardest is 32% better efficacité (23.0 vs 34.0 J/TH). The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The Bitmain S19k Pro and Whatsminer M30S+ diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitmain S19k Pro 20% more hashrate (120 vs 100 TH/s)
- Bitmain S19k Pro 19% better power draw (2,760 vs 3,400 W)
- Bitmain S19k Pro 32% better efficacité (23.0 vs 34.0 J/TH)
- Whatsminer M30S+ 21% better weight (14.5 vs 11.5 kg)
- Whatsminer M30S+ 23% more heat output (9,417 vs 11,601 BTU/hr)
Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Bitmain S19k Pro | Metric | Whatsminer M30S+ |
|---|---|---|
| $313 | Upfront cost (MSRP) | $1,800 |
| -$2.31 | Daily net profit | -$4.56 |
| -$1,155 | Net after 1 year | -$3,465 |
| -$1,996 | Net after 2 years | -$5,130 |
| -$2,837 | Net after 3 years | -$6,794 |
| 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.
