The processing power for the Switch is entirely contained within the tablet, meaning that theoretically it shouldn’t perform any differently whether you, or Jimmy Fallon, is playing Zelda at home or on a train. But a report from video game blog Let’s Play Video Games suggests the console will actually be able to overclock its processor—a common PC-gaming practice for getting more power out of a processor by forcing it to run faster than the manufacturer says it’s supposed to—when it’s plugged into the dock. That means playing at home may be faster than on the tablet. The dock also has a built-in fan that will help cool down the system when it’s overclocking, so as to not overheat or damage the machine.

Nintendo wasn’t immediately available to confirm the report, but it does stand to reason that the Switch’s relatively large dock serves some function other than just sending video from the device to a TV screen. Nintendo told Fallon that it intends to release more information about the console on Jan. 12, so stay tuned.
