PSP clockspeed upped to 333MHz after 3.50 firmware update

Update: The availability of the PSP's full CPU speed only affects in-development titles, a SCE representative has told Shacknews. Previously released PSP games continue to operate at the speed they were originally programmed for, and do not see any sort of change in performance or battery life.
Original story: A Sony Computer Entertainment representative has confirmed to Shacknews that developers can now take full advantage of the PSP's CPU following the late May release of the system's version 3.50 firmware. Rumors of the unlocking were initially reported by fansite PSP Updates via an unnamed source.



Previously, developers were only able to run the CPU at 266MHz rather than its full potential clock speed of 333MHz, though most games ran at only 222MHz. High Impact Games' Ratchet & Clank: Size Matters, released in February, is said to run at 266MHz. Hackers long ago discovered methods to run the PSP's CPU at full speed, the benefits of which include a smoother framerate for certain games, at the cost of reduced battery life. There is no word yet if this update enables previous PSP releases to run at 333MHz, something hacked PSP firmware has enabled in the past.
