Handheld's CPU power apparently restricted during multiplayer sessions

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.

This is all very bizarre IMO. Why would Sony do things like this? I wonder if it has more to do with over-drawing current (i.e. machine becomes unstable) rather than extra battery life draining?

I hope they get their act together for the PSP2. Online/WiFi play is rapidly becoming one of the biggest strengths of the DS system.

This also impacts their plans for using the PSP as an accessory for the PS3.
