Those numbers are big, but mean very little. A badly ported game will still run bad.
The key for consoles, perhaps for a little while, has not been the specs, Xbox 360 proved that, it has been the hype, and the ease of porting.
For example: Wii U. It very well could be more powerful then the other consoles right now, but since it is hard to port to, and no one really wanted to buy one, no one is porting their games to it.
