Apple not giving up its ARM SoC GPU crown anytime soon

anandtech - A6X GPU performance

It was supposed that Apple just beefed up the CPU in A6X, but the GPU got the same improvement almoust doubling already mindboggling performance of A5X quad core GPU getting it leaps ahead of competition. This enables even the best looking games played in native resolution (while on the 3rd gen iPad the downscaling is required). We should see some fantastic looking games (and upgrades for many already out there) really soon.

As the CPU upgrade was mostly overlooked as "nice to have" with performance of 3rd gen iPad already up there, the GPU brings a real benefits and makes a bigger case for 4th gen iPad at least for gamers. Tegra 4 and others will not have easy time outperforming it (if they ever do).
