new iPad3 A5X Processor - bigger is better?

I have post iPad3 new iPad teardown last week. Thanks to ChipWork, now we can see what is inside the A5X processor being use on ipad3 new iPad.

To compare how big is A5X, here are A4 and A5 die photo as well:

Apple A4 Polysilicon Die Photo = 7.3 mm x 7.3 mm

Apple A5 Polysilicon Die Photo – 10.09 mm x 12.15 mm

And finally, Apple A5X Polysilicon Die Photo – 12.90 mm x 12.79 mm

Yes, it is really huge, it is even bigger than dual core Sandy Bridge (Sandy Bridge-H-2 and Sandy Bridge-M-2).

ChipWorks even make two high resolution images of A5X for wallpaper:

–> Download 2056 px tall version

I wonder if the huge silicon contribute to new iPad heating issue?
