Why the a5x isn't 4x as fast as the tegra 3

Apple used a benchmark run against a honeycomb equipped transformer prime to get their 4x performance figures. Unfortunately, this is misleading since honeycomb doesn't support gpu acceleration.  So yes the a5 and a5x are that much faster when comparing gpu rendering versus CPU rendering but in real life with ics the a5 and x variants are likely to be similarly performing to a tegra 3. The a5 does not wipe the floor with the t3 and the a5x is pretty much the bare minimum to keep up with the increased requirements of the near retina display of the ipad3.
Check out annads excellent review of the new iPad http://www.anandtech.com/show/5663/analysis-of-the-new-apple-ipad/
We have slightly differing opinions on real world performance of the gpus, I would differ to andrew as he has more numbers and pretty charts.
