Powervr Sgx

Just like the original iPad debuted with an Apple A4 chip, iPad 2 is coming with an Apple A5 chip. What does that mean? In typical fashion Apple has been short on details saying only that it's dual-core, 1GHz, 2x faster for computational tasks and 9x faster for graphics, all while preserving the 10 hour battery life that made the A4 famous. They don't think we need to worry about what CPU or GPU they're using and how much RAM is on board to let that power breathe. But here's the thing -- many of us want to know exactly that.

This is the chip that will also power the 2011 iPhone 5, iPod touch 5, and Apple TV. We want answers. We can handle answers! So... stick with us after the break for everything we know about the new Apple A5 chip... and what we can guess.

The iPhone 3.2 SDK for iPad has officially outs the PowerVR SGX as the graphics core inside Apple's A4 chipset:

Using OpenGL ES on iPad is identical to using OpenGL ES on other iPhone OS devices. An iPad is a PowerVR SGX device and supports the same basic capabilities as other SGX devices. However, because the processor, memory architecture, and screen dimensions are different for iPad, you should always test your code on an iPad device before shipping to ensure performance meets your requirements.

MacRumors is reporting that Apple's new iPhone 3GS, while indeed using Imagination Technologies' PowerVR graphics core, may just have a little more under the hood than previously thought:

iPhone developers, however, have discovered that the iPhone 3GS has extension files named "IMGSGX535GLDriver" suggesting that the new iPhone uses the more powerful graphics processor intended for "high end" mobile devices. This may not be entirely conclusive evidence by itself but it is consistent with a report from a Anandtech commenter who claims to have heard directly from Apple engineers at WWDC that the iPhone 3GS does indeed use the SGX 535.
