All of the processing power for the Nintendo Switch comes from the main unit rather than its dock, but when the system is undocked its internal processor is clocked at a lower speed. While it was believed the GPU was locked at 307.2 MHz when undocked, it turns out there’s an available boost mode that’ll bring it to 384 MHz.
Its boost mode was leaked from developer documentation.
The extra power gives developers a little more room to play with, potentially helping more games to run at full performance on the go.
The Switch’s clock speed drops when undocked since the resolution is capped at 720p.
