Up until now it was generally believed that the Wii U would pack about 1.5 times the punch of an Xbox 360 or PS3, a rumor fueled largely by Nintendo's own assertions of the same. They even claimed as much at E3—trust us, we were there.

It turns out, based on information obtained by Wii U Daily from an unnamed Japanese developer currently porting a PS3 game to the new system, that those estimates may have been slightly generous. The Wii U will reportedly carry a quad core 3GHz CPU, 768 MB of RAM, and an unknown, 40nm ATI-based GPU. This puts it at around the same power as an Xbox 360. At best, it might be a slightly more robust system.

Their source also mentioned that Nintendo's been considering another version of the console with a full gig of RAM, which might grant it an extra bit of brawn. There's still a ways to go until the console's release, though, so consider these specs less-than-final, if you please.

Do you think Nintendo should go back to the drawing board, or will these rumored specs be sufficient for the Wii U? Let us know in the comments or on Twitter or Facebook.
