PSPgo has a 480MHz processor, will be underclocked to 333MHz

Despite being underclocked like it’s predecessors, the PSPgo will actually feature an upgraded processor capable of maxing out at 480 MHz.
Sony hasn’t said much about this upgraded processor but if the past is anything to go by, we’ll be seeing that full 480Mhz of processing goodness at some point in the future. If you recall, the original PSP had a 333MHz processor but was underclocked to 266MHz. A bit into it’s life span Sony decided to unlock the full 333MHz of power giving developers a bit of room to play around with.
So again, it’s a safe bet that Sony will unlock the full 480MHz of processing power at some point however when remains unknown.
