PSP Wi-Fi reduces processor speed

cjmnews | August 13, 2007 | News | Playstation Portable

With the release of the 3.50 PSP update the processor speed was no longer limited to 222 MHz, letting it run at 333 MHz. Apparently the full processor speed can not be used while using Wi-Fi at the same time.

Although PSP firmware version 3.50 introduced a new clock control function, Beyond3D discovered that the portable's full clock speed is only available with Wi-Fi disabled, meaning that during network play the CPU clock is limited to 222MHz.

  How can it be any less? Are you *bleep*ing stupid?
  
  The PSP used WiFi back when it had 222MHz, so even then it had to have been using up some performance for the WiFi. Now with 333mhz it's still faster than 222mhz.
  
  GOOD GAME HARVESTMOONBOY.

    Good point Volacide, and your right, i mean if it lowered the Processing speed surely 222MGz would have been lower to that due to WiFi

  2) You don't have the faintest clue about what this article was talking about

Harvestmoon boy and Final blade, do you even know what this is about?
The PSP used to run at 222Mhz but the newer firmwares allow it to run at 333Mhz, which is the fastest speed possible without instability, overheating etcetera. People who are active in the homebrew community have been using 333Mhz for ages, and it turned out the built-in network card can get damaged due to heat when the CPU is running at 333Mhz. Therefore, Sony has added security which clocks the CPU to 222Mhz to avoid damaging the network card. It's as simple as that, no speed is lost. Quite frankly, you don't notice a difference when browsing on 333, 300, 266 or 222Mhz anyway, I could know as a homebrew user.
