Video shows iPhone 5 With switchable GPUs

Posted on Sep 29 2011 - 12:44pm by Thomas Sharp

A new video that has surfaced on the web shows an iPhone prototype with a software-based developer setting that enables users to switch between graphics processing units.

The video, which was sent to Apple enthusiast site Cult of Mac, purportedly shows a fifth-generation iPhone in action. Like other prototype devices from Apple, the smartphone features a ‘Developer’ section in the Settings page that enables users to perform all sorts of things.

While the authenticity of the video is yet to be verified, it shows an iPhone built for testing purposes that enables developers to choose between two graphic processors, the SGX535 GPU, which is found in the iPhone 4, and the SGX545, a faster processor that is yet to be seen in an Apple mobile device.

The SGX545 was first announced in January 2010 and it features full support for OpenGL 3.2 and OpenCL 1.0. It also has real-world performance of 40 million pps (polygons per second) at 200 MHz. The SGX535 can only produce 28 million pps, while the newer SGX543 can produce 35 million pps.

While the video claims to show an iPhone 5 prototype, it seems to look a lot like the iPhone 4. It is possible that its graphics switching functionality was enabled via a hack, or has been faked through another method.

The video suggests that the upcoming iPhone could sport a new FPU that will back up the phone’s dual-core A5 processor, providing users with better gaming experience on their phones.

Do you think the video is real or fake?
