Performance per Watt: The RK3576 vs RK3588 Energy Ledger

Benchmarks alone mislead. Performance per watt is the real cost metric for always-on hardware.

How to compute efficiency

Idle power: RK3576 units at 1.5-2 W vs RK3588 at 2.5-3.5 W — about 10-15 kWh more per year for 7×24;
Loaded efficiency: under light load (<30% CPU) RK3576 delivers more per watt; heavy loads favor RK3588;
Conclusion: RK3576 for steady light services, RK3588 for bursty compute, or both — 3576 resident, 3588 on demand.

Multiply idle watts by 8760 hours before comparing — the most-forgotten multiplication in always-on selection.
