A8X GPU in iPad Air 2 Features Semi-Custom 8 Cluster Series6XT Design

New information reveals that the Apple A8X GPU found in the iPad Air 2 features an unusual semi-custom 8 cluster Series6XT design.
 

Taking a look at a die shot of the GPU provided by ChipWorks, the site was able to identify eight GPU clusters. Notably, the layout looks a lot like that of the GX6450 with another GX6450 placed right above it.



Since Imagination doesn't have an official eight cluster Series6XT GPU design, AnandTech believes that Apple is modifying Imagination's designs to fit their needs.
