The Bitmain Antminer S19 XP was the efficiency king of the S19 generation, delivering 140 TH/s at 21.5 J/TH using the BM1366 ASIC chip. When it launched in late 2022, the S19 XP set a new benchmark for air-cooled mining performance that would not be surpassed until the arrival of the S21 series.
Even in 2025-2026, the S19 XP remains a relevant and capable machine for operations with access to reasonably priced electricity. Its combination of solid hashrate and competitive efficiency makes it a strong used-market option and a machine worth keeping in service rather than retiring.

Performance Analysis
The S19 XP’s 21.5 J/TH made it the most efficient S19-generation Antminer upon release. It represents a 27% efficiency improvement over the S19j Pro (29.5 J/TH) and a 27% improvement over the S19 Pro (29.5 J/TH). It also edges out the S19k Pro (23 J/TH) by about 7%.
Against the current generation, the S19 XP falls behind the S21 (17.5 J/TH) by about 23% and the S21 Pro (15 J/TH) by about 43%. However, the S19 XP is available at significantly lower prices on the secondary market, which can make the total cost of ownership competitive depending on your time horizon and electricity rate.
Compared to MicroBT’s offerings, the S19 XP is more efficient than the Whatsminer M50S (26 J/TH) but falls behind the Whatsminer M60S (18.5 J/TH).

Profitability Snapshot
Estimated daily revenue and cost at current network difficulty (approximate, based on typical 2026 conditions). Actual results depend on Bitcoin price, network difficulty, and pool fees.
| Electricity Rate | Daily Power Cost | Monthly Power Cost | Viability |
|---|---|---|---|
| $0.05/kWh | $3.61 | $108 | Profitable — strong performance at cheap power rates |
| $0.08/kWh | $5.78 | $173 | Marginal to profitable — viable but monitor difficulty trends closely |
| $0.10/kWh | $7.22 | $217 | Tight — approaching break-even for many operators |
| $0.12/kWh | $8.67 | $260 | Likely unprofitable — consider underclocking via firmware or dual-purpose heating use |

Best Use Cases
Mining Farms with Cheap Power: At sub-$0.06/kWh electricity rates, the S19 XP remains a profitable workhorse. Its lower acquisition cost on the secondary market combined with 140 TH/s of hashrate makes it a strong value proposition for operations that have already depreciated their infrastructure.
Home Mining: The S19 XP’s 3,010W power draw is moderate for a full-size ASIC, and it fits comfortably on a 15A 240V circuit. With a D-Central cooling shroud, the exhaust heat can be ducted for home heating during cold months.
Dual-Purpose Heating: At 3,010W, the S19 XP outputs approximately 10,270 BTU/h of heat. For Canadian and northern-climate miners, this waste heat offsets home heating costs significantly. See our Bitcoin Space Heater vs Electric Heater analysis.
Firmware Optimization Play: The BM1366 chip responds exceptionally well to third-party firmware. Running Braiins OS+ with autotuning can improve the S19 XP’s effective J/TH by 5-10%, potentially extending its profitable lifespan by months.
Secondary Market Value: The S19 XP holds its resale value well relative to other S19-era machines due to its superior efficiency. This makes it a lower-risk purchase for operators uncertain about their long-term commitment.

Common Issues & Repair
Common issues with the Antminer S19 XP include:
- Hashboard failures: BM1366 chip degradation is the most common issue as these units age. D-Central stocks BM1366 replacement chips and replacement S19 XP hashboards.
- Fan errors: After years of continuous operation, fan bearings wear and speed sensors degrade. Compatible replacement fans are available.
- Temperature warnings: Dust accumulation over time reduces cooling efficiency. Regular cleaning and thermal paste replacement extends the unit’s life.
- Control board issues: Power surges and firmware corruption can damage control boards. Replacement control boards are available.
