As usual Anandtech has one of the best reviews. My only complaint is the CPU benchmarks are more or less useless. I understand there aren't any good cross platform benchmarks right now but using JS benchmarks is completely inaccurate. Not only are there major variations between scores on the same device (across different browsers and versions) but the same browser isn't even available on both platforms.

I'd love to see how the A7 really stacks up against the Snapdragon/Tegra but it doesn't seem like we'll be seeing that any time soon.
