How so? I invite constructive criticism.
Tegra 5 is an ARM chip. Your PC won't have it included. It's for mobile devices only.
EDIT: Okay seriously, unless N4G has no idea what an ARM-chip is, how could this receive disagrees?
The PS4 will be more like a PC (x86) than something with the Tegra 5 (ARM/iPad/Mobile etc.)
I'm very interested to see why someone would disagree with this. The second paragraph is just personal opinion -- and the first paragraph, probably why people disagreed, is a fact.
A6X in the iPad 4 mops the floor with what the Vita has. You won't be seeing Vita quality games full-screen on the iPad 4 'cause iOS is slow and uses a lot of resources, and also the screen resolution of the Vita is only around 500x300, whereas the iPad's native resolution is 2000+ ...
OS performance aside, the Vita is about the same power as the iPad 3 and less powerful than the iPad 4 (A6X) for graphics.
I don't know how Tegra 5 compares exactly, but we already know about Haswell and how it can fit into slim computers such as the Surface for example. I'm far more impressed about the advances made to x86 processors rather than ARM.
I'll spend some time proofing. Thanks
