PSP limited by wireless play?

According to a report on Beyond3D, Sony's PlayStation Portable loses a third of its processing power when the WiFi adapter is enabled.

The tests were run using the clock control function in the Firmware 3.5 update, which allowed the clock to run at its full 333MHz frequency.

However, when the wireless adapter was enabled the speed dropped to 222MHz.

Speculation has followed that games with multiplayer elements are therefore throttled slightly in terms of the power they're able to tap, while other games that are single-player only face no such restrictions.

When contacted on the matter by GamesIndustry.biz, Sony declined to comment.
