PSP God of War's boosted clock speed comparison
The firmware update unlocks the system's true capabilities, upping the system's measly 222MHz processing speed to a respectable 333MHz. It doesn't make your old games look any better, but developers of new games on the system can reap the rewards of the 50 percent processing speed boost. Just check out the video comparison of the game running at the two different clock speeds above, and see how Ready at Dawn gussied up their handheld take on the PS2 swan song.
