Profitability Comparison
Bitmain Antminer D3 (19.3Gh)
StrongU STU-U6
Based on BTC price of $78,210 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Our scoring model gives the nod to the StrongU STU-U6, which leads on 2 of 4 weighted factors (efficacité, hashrate). Where it pulls away hardest is 2180% more hashrate (0.0 vs 0.4 TH/s). The Bitmain Antminer D3 (19.3Gh) claws back ground on consommation électrique and score de minage domestique. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
Spec Deltas
The Bitmain Antminer D3 (19.3Gh) and StrongU STU-U6 diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- StrongU STU-U6 2180% more hashrate (0.0 vs 0.4 TH/s)
- Bitmain Antminer D3 (19.3Gh) 39% better power draw (1,350 vs 2,200 W)
- StrongU STU-U6 93% better efficacité (69,948 vs 5,000 J/TH)
- Bitmain Antminer D3 (19.3Gh) 24% better weight (5,500 vs 7,200 kg)
- StrongU STU-U6 63% more heat output (4,606 vs 7,506 BTU/hr)
- Bitmain Antminer D3 (19.3Gh) 19% more score de minage domestique (31.0 vs 26.0)
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.
| Bitmain Antminer D3 (19.3Gh) | Metric | StrongU STU-U6 |
|---|---|---|
| — | Upfront cost (MSRP) | $5,235 |
| -$3.24 | Daily net profit | -$5.26 |
| -$1,182 | Net after 1 year | -$7,156 |
| -$2,365 | Net after 2 years | -$9,078 |
| -$3,547 | Net after 3 years | -$10,999 |
| — | 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.
