In comparison to 3DS, PSP2's processing power is "comparable to the difference which exists between PSP and DS".
That's according to an Edge source with experience of working on Sony's supposedly soon-to-be-announced portable.
It was rumoured yesterday that PSP2 is as powerful as the PS3 and set for release as early as this Christmas.
Edge's source corroborated the first claim, describing it as "a perfectly reasonable description of the hardware's capabilities".
According to unconfirmed reports, 3DS sports two 266MHz ARM11 CPUs, along with a 133MHz GPU, 4MBs of dedicated VRAM, 64MBs of RAM, and 1.5GBs of flash storage.
But that'd still put it behind the PSP2, if it is indeed carrying specs similar to that of Sony's home console.
We should find out more about both of the new portables and their capabilities over the next few weeks, with Nintendo holding 3DS press events in Amsterdam and New York on January 19, and Sony reportedly due to officially announce PSP2 eight days later in Japan.
