The new PSP Go isn’t just a smaller, UMDless version with a new design; it actually has a faster processor. According to some FCC documents, which were filed by Sony and uncovered by Sony Insider, the PSP Go’s processor is about 40% faster than its predecessor. The original unit was capable of about 333MHz, while the newest device, which comes out later this year, can reach 480MHz.

What does this all mean? We’re not to sure, actually. They might have just raised the speed to use PSP Go features like accesses to an in-game XMB. However, it could definitely make a difference in-terms of games and maybe one day we could see PSP Go exclusives. Although, if that were the case, don’t expect to see anything anytime soon. In fact, even though the portable system can reach faster speeds, I think Sony will most likely lock it to the current 333MHz, much like they did when the PSP first came out.

If the company feels like they need to sell more PSP Go units, that is when we could most likely see the increase of speeds and exclusives.
