iPhone 5 vs PS Vita and PS3 and WII U

Now that the iPhone 5 SoC is known, I want to know from well to know members about the new iPhone 5 CPU/GPU power in comparison to the PS VITA and the PS3. I heard during the launch that the iPhone 5 can produce console quality games. I also want to know how much more powerful the WII U is compared to the iPhone 5. I know the iPhone 5 is not a perfect gaming gadget because it lacks physical buttons and that other kind of stuff, but I and am sure alot of other people would love to know whether it packs the power to compete with the aforementioned competing products.

So what do you think??
