Ryan Smith, AnandTech:
[It] has become clear that with A8X Apple has once again thrown us a curveball. By drawing outside of the lines and building an eight cluster GPU configuration where none previously existed, the A8X and its GXA6850 GPU are more powerful than even we first suspected. Apple traditionally aims high with its SoCs, but this ended up being higher still.
The numbers here are just off the charts. The iPad is aching for software features that can really take advantage of performance like this.
