Profitability Comparison
Antminer S17 Pro
Antminer S19j Pro
Based on BTC price of $78,139 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
A cross-generation comparison between the S17 Pro (2019 era) and the S19j Pro (2021 era). Two years of chip development separate these models.
The S19j Pro is vastly more efficient and reliable. The S17 Pro was notorious for thermal issues and has largely been retired from profitable operation at current difficulty levels. Only miners with near-free electricity should consider the S17 Pro.
Spec Deltas
Here is every spec where the Antminer S17 Pro and Antminer S19j Pro actually differ, with the gap quantified:
- Antminer S19j Pro 79% more hashrate (56.0 vs 100.0 TH/s)
- Antminer S17 Pro 27% better power draw (2,212 vs 3,050 W)
- Antminer S19j Pro 23% better efficiency (39.5 vs 30.5 J/TH)
- Antminer S17 Pro 28% better weight (9.5 vs 13.2 kg)
- Antminer S19j Pro 38% more heat output (7,547 vs 10,407 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.
| Antminer S17 Pro | Metric | Antminer S19j Pro |
|---|---|---|
| — | Upfront cost (MSRP) | $2,500 |
| -$3.30 | Daily net profit | -$3.72 |
| -$1,203 | Net after 1 year | -$3,859 |
| -$2,405 | Net after 2 years | -$5,219 |
| -$3,608 | Net after 3 years | -$6,578 |
| — | 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
Can the Antminer S17 Pro still mine profitably?
Only at extremely low electricity rates (under $0.03/kWh). The S17 Pro's efficiency of approximately 40 J/TH makes it unprofitable at typical residential rates. It may still have value as a space heater.
Why was the S17 Pro considered unreliable?
The S17 series had well-documented thermal management issues that caused premature hashboard failures. The S19 series resolved these with improved cooling design and more robust components.
