The scores in the IT Pro article are not right, but it does not change the fact the iPhone 5 looks set to be pretty fast. Geekbench takes in to account processor and memory speed, so i would assume poor read speeds from cheap micro sd cards were to blame for IT Pros poor scores. In real life, the s3 pips the iPhone 5, but the 5 is faster than the One X. Considering the power savings from running dual cores, that is an impressive feat!*
*Assuming the scores are legit. It is possible to fake geekbench uploads...
