TiPb Answers: Apple A5 chip -- what we know and what we guess

By Rene Ritchie, Thursday, Mar 3, 2011 a 8:58 am

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.

Imagination at CES: POWERVR SGX545 Graphics Core... Could it be the 4th Gen iPhone GPU?

By Rene Ritchie, Friday, Jan 8, 2010 a 3:50 pm

Imagination, which counts Apple as one of its owners, has provided the GPU (graphics processing unit) for every iPhone to date, including the current iPhone 3GS PowerVR SGX, so it's not unreasonable to assume the latest, greatest PowerVR SGX545 introduced at CES will be in the 4th generation iPhone, likely to be announced in June/July:

SGX545 will also deliver OpenGL ES 2.x and OpenGL 3.2 to deliver class leading 3D graphics performance, and will also support OpenCL 1.0 full profile capability which will enable mobile and embedded applications to take maximum advantage of the capabilities offered by these GPU APIs for both 3D graphics and general purpose applications.

iPhone 3GS Graphics Even More Powerful than Imagined?

By Rene Ritchie, Friday, Jun 26, 2009 a 10:28 am

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.

Inside the New iPhone 3G S Processors: More than Just Mhz

By Rene Ritchie, Saturday, Jun 13, 2009 a 6:52 am

Anandtech gives their usual in-depth look at the processors inside Apple's new iPhone 3G S. First the CPU, the new ARM Cortex A8 and the short of it is -- if the iPhone 2G and 3G were old 486 PCs, the iPhone 3G S would be a Pentium:
