Tip is a full automatic and the F1/DSG is a manual gearbox with automatic engagement.
The Tip in the 997 Turbo is from MB-AMG, same 5-speed box AMG uses in their car, and as auto box goes this one is as bulletproof as they gets, it's actually has a higher torque cap than either the Ferrari F1 or the VW/Audi DSG.
In the 997 Turbo the tip's torque converter allows the turbos to spool up first before the launch, hence faster acceleration. It also shifts faster than the 6-speed manual and that's why the Turbo is faster.
