Budget, up to $400 approx,
The Sony Experia SP seems to tick all the boxes, my only concern is that, is Dual-core 1.7 GHz Krait CPU good enough, has a Adreno 320 GPU, I think the CPU is about as fast as a Quad-core Cortex-A9 (might be wrong) which puts it on par Galaxcy S3 and HTC One X.
Some of the cheap quad core phones have cortex a5 cpu's, so I would presume the Krait Duals are quicker?
Any thoughts and recommendations on models in price range and anyone has a Xperia SP and how they find it.
I can't find any charts etc for mobile phone CPU speeds online other than computer cpu's.
