At the heart of Raspberry Pi Zero 2 W is RP3A0, a custom-built system-in-package designed by Raspberry Pi in the UK. With a quad-core 64-bit ARM Cortex-A53 processor clocked at 1GHz and 512MB of SDRAM, Zero 2 is up to five times as fast as the original Raspberry Pi Zero. As for heat dissipation concern, Zero 2 W uses thick internal copper layers to conduct heat away from the processor, sustaining higher performance without higher temperature.
