Table 4-1 shows power consumption at various SoC states and the scalability of power and performance. By leveraging low power mode implementation and techniques, AM62 processors achieve less than 500-mW power consumption for a single A53 core running at 1 GHz. The power consumption is almost half of the power consumption achieved by similar low power and low-cost processors in previous generations. AM62x processor power can still be less than 1 W when Quad A53 cores run a stressful application on all four cores at 1.4 GHz.
