A PSP has a MIPS R4000-based CPU designed for a clock speed of 333MHz, almost every single PSP game runs at 222MHz. So far the firmware dint squeeze the whole juice from a PSP, but now the latest firmware has enabled the PSP to make full use of its resources. The new firmware v3.5 set clock speeds to 333MHz which is the real capacity of a PSP.

Some games like Ratchet & Clank need a clock speed of up to 266Mhz. The speed won’t make any difference for the already existing games but in the case of new games, if they really require more speeds then only the speeds will be used accordingly.
