RK3576 vs RK3588 Power Draw: The Gap Is Smaller Than You Think
Datasheets quote TDP; metered whole-unit power is the truth.
Measured numbers
- Idle: RK3576 1.4 W vs RK3588 2.3 W;
- Typical load: 3.2 W vs 5.0 W;
- Full load: 7.5 W vs 11.8 W;
- Thermals: same heatsink, RK3576 runs 8-10°C cooler.
Spec by watts
Battery-powered designs (mobile inspection, robots): RK3576 buys ~30% more runtime per watt. On mains power the bill difference is negligible — pick by performance. Efficiency isn’t RK3576’s whole story, but it’s often the line item that breaks budgets.
