A website is claiming that the new 333MHz clock mode on the PSP is only available when WiFi is disabled, so therefore during network play the CPU clock is limited to a lowly 222MHz. They claim that this has some slightly worrying consequences for games developers.

With the release of the Firmware 3.5 a new clock control function was added and now the technical requirements checklist allows software to run at the full 333MHz clock with the bus clock also reaching its maximum frequency of 166MHz. However, as Beyond3D is able to confirm, the full clock is only available with WiFi being disabled, i.e. during network play the CPU clock is limited to 222MHz.

This has in fact some consequences for PSP game development. Game titles with network play could effectively be either limited to using 222MHz only during single player mode, or to using a downgraded engine and assets for multiplayer mode, which could complicate the development process. Meanwhile single player-only titles like God of War can take full advantage of the speed boost.
