Chipworks, which provided some details on the new iPad during its teardown at the end of last week, has taken some extremely detailed die photos of the A5X processor in the new iPad.

One of the biggest changes in the new A5X is the sheer size of the die. The A5X is 310% larger than the A4, the processor in the iPhone 4 and the original iPad. Each of the four GPU cores take up a huge chunk of the A5X, each GPU core is larger than the individual ARM cores of the CPU.

For fans of die photos, Chipworks is also offering a 1200px wide unmarked die photo of the A5X to be used as iPad wallpaper.

Update: Chipworks has updated their blog post with a iPad 3-ready 2056px wide shot of the A5X.

I may be slow to the game here, but does anywhere offer a wallpaper of the iPad/iPhone's complete innards? It would be kind of cool when swiping somewhere knowing that I'm swiping across the CPU or RAM etc...

You know, that would be pretty cool! I can't see myself using it as a home screen wallpaper, but it would be cool for the lock screen--kind of like those cases that make your phone look transparent!

That's what it takes for purty graphics on the retina iPad. They'll be able to go back down to dual core when they start using ImgTec Rogue cores.

So, we can look ahead to the next iPad release already? Dual core GPUs, with the same performance, but (presumably) lower power draw than the quad-core so longer battery life and less heat generation?

That's what I anticipate. The next generation ImgTec cores will be a huge jump in performance, and a dual core will actually wipe the floor with quad core version of this. However, nothing seems certain since the A5X isn't really suitable for the next iphone. So, we need to see if the iphone and iPad start getting different versions of the same SoC or different SoCs all together. I think the bottom line is that if Apple unveils a new "A" processor for the next iPad, it will probably be 28/32nm and feature cortex A15 cores and ImgTec "Rogue" GPU cores. The jump in performance will be like from 3G -> 3GS or A4 -> A5.

Interesting.

This makes me wonder where mobile GPUs can go from there. The framerate is essentially capped by the vsync; and the resolution going higher - at the current display size - is pointless.

By my (very limited) understanding of 3D apps/games development, putting more complex scenes (more models and/or higher poly models) requires faster CPU performance rather than just GPU. As for more complex lighting models, & lighting effects (HDR bloom, real shadows, smoke effects etc) I haven't a clue if these rely more on CPU or GPU.

If mobile graphics is anything like desktop graphics, the CPU only starts to matter once you get to the higher 60+ framerates. Otherwise, CPU has a limited influence on graphics performance.
