Profitability Comparison
Bitmain Antminer S21e XP Hyd 3U
Bitmain S19k Pro
Based on BTC price of $79,126 and current network difficulty as of May 15, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the Bitmain Antminer S21e XP Hyd 3U edges it: 4 of 6 factors go its way (efficiency, hashrate, home mining score, noise level). Where it pulls away hardest is 617% more hashrate (860 vs 120 TH/s). That said, the Bitmain S19k Pro isn't beaten everywhere — it still wins power consumption and price-performance. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.

- Bitmain Antminer S21e XP Hyd 3U 22% more home mining score (44.0 vs 36.0)
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.
| Bitmain Antminer S21e XP Hyd 3U | Metric | Bitmain S19k Pro |
|---|---|---|
| $10,899 | Upfront cost (MSRP) | $313 |
| $4.48 | Daily net profit | -$2.25 |
| -$9,263 | Net after 1 year | -$1,136 |
| -$7,627 | Net after 2 years | -$1,959 |
| -$5,990 | Net after 3 years | -$2,782 |
| Takes ~6.7 years to pay back at current rates | 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.
