The short version
The S23 Hyd is the machine to buy when power is expensive. At 9.50 W/Th it is within a rounding error of the A4 Ultra, but it pulls only 5.51 kW, so a site can host twice as many units per megawatt. For operators paying above $0.14/kWh this is consistently the highest-margin unit in the catalogue.
- 9.50 W/Th — best-in-class for its power class
- 5.51 kW draw fits existing S21 Hydro infrastructure
- Bitmain APW hydro PSU with dual-loop redundancy option

Gross revenue is the catalogue figure for this unit. Net subtracts electricity at your rate only — pool fees, hosting and hardware amortisation are not included, and payouts move with network difficulty.

Switching targets is a firmware and pool-config change, not a hardware change. Most operators point at the top line and let a profit switcher handle the rest.
