Profitability Comparison
Antminer S17
Antminer S19
Based on BTC price of $62,977 and current network difficulty as of Jun 24, 2026. Actual results vary.
Verdict
Two generational flagships from Bitmain. The S17 defined an era, and the S19 succeeded it with a new chip architecture.
The S19 wins on every metric that matters for mining profitability. The S17 is only relevant as a used-market bargain or for space heater conversion, where its heat output and low price create value.
Spec Deltas
Here is every spec where the Antminer S17 and Antminer S19 actually differ, with the gap quantified:
- Antminer S19 70% more hashrate (56.0 vs 95.0 TH/s)
- Antminer S17 22% better power draw (2,520 vs 3,250 W)
- Antminer S19 24% better efficiency (45.0 vs 34.2 J/TH)
- Antminer S17 34% better weight (9.5 vs 14.4 kg)
- Antminer S19 29% more heat output (8,598 vs 11,089 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.
| Antminer S17 | Metric | Antminer S19 |
|---|---|---|
| — | Upfront cost (MSRP) | $2,000 |
| -$4.27 | Daily net profit | -$4.79 |
| -$1,560 | Net after 1 year | -$3,748 |
| -$3,120 | Net after 2 years | -$5,496 |
| -$4,679 | Net after 3 years | -$7,245 |
| — | 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.

Frequently Asked Questions
Is the S17 still worth running?
Only at very cheap electricity rates or when repurposed as a space heater. For pure mining, the S19 is a far better investment at current used prices.
Are S17 parts still available?
Yes, D-Central maintains parts inventory for the S17 series including hashboards and control boards. However, prices reflect diminishing demand.
