Profitability Comparison
Bitmain S19k Pro
FluMiner T3
Based on BTC price of $79,088 and current network difficulty as of May 15, 2026. Actual results vary.
Verdict
Based on our multi-factor analysis, the FluMiner T3 wins on 4 of 6 factors (efficiency, power consumption, home mining score, noise level). Its biggest concrete edge: 38% better power draw (2,760 vs 1,700 W). The Bitmain S19k Pro claws back ground on hashrate and price-performance. 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 FluMiner T3 diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Bitmain S19k Pro 4% more hashrate (120 vs 115 TH/s)
- FluMiner T3 38% better power draw (2,760 vs 1,700 W)
- FluMiner T3 36% better efficiency (23.0 vs 14.8 J/TH)
- FluMiner T3 33% better noise (75.0 vs 50.0 dB)
- FluMiner T3 13% better weight (14.5 vs 12.6 kg)
- Bitmain S19k Pro 62% more heat output (9,417 vs 5,800 BTU/hr)
- FluMiner T3 56% more home mining score (36.0 vs 56.0)
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 S19k Pro | Metric | FluMiner T3 |
|---|---|---|
| $313 | Upfront cost (MSRP) | $1,601 |
| -$2.26 | Daily net profit | $0.11 |
| -$1,137 | Net after 1 year | -$1,562 |
| -$1,960 | Net after 2 years | -$1,524 |
| -$2,784 | Net after 3 years | -$1,485 |
| Does not pay back at current rates (negative daily profit) | Payback period | Takes ~41.6 years to pay back at current rates |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.

Frequently Asked Questions
Is the Bitmain S19k Pro or FluMiner T3 more profitable?
At the current BTC price and a $0.10/kWh electricity rate, the FluMiner T3 is more profitable at $0.11/day compared to $-2.26/day for the Bitmain S19k Pro. Profitability depends heavily on your electricity rate — use the selector above to calculate with your actual costs.
Is the Bitmain S19k Pro or the FluMiner T3 better for noise-sensitive spaces?
The FluMiner T3 is quieter at 50 dB compared to the Bitmain S19k Pro at 75 dB. For home mining, lower noise levels make a significant difference in livability.
Which is better for home mining, the Bitmain S19k Pro or FluMiner T3?
The FluMiner T3 scores 56/100 on our Home Mining Score (vs 36/100 for the Bitmain S19k Pro). This composite score factors in noise, power requirements, heat output, size, and setup ease — all critical for residential mining.
What is the efficiency difference between Bitmain S19k Pro and FluMiner T3?
The Bitmain S19k Pro runs at 23.0 J/TH while the FluMiner T3 runs at 14.8 J/TH — a difference of 8.2 J/TH. Lower efficiency means less electricity per terahash of mining power, directly reducing operating costs. In relative terms that is 36% better efficiency (23.0 vs 14.8 J/TH).
