When Phil Schiller, Apple’s Senior Vice President of Worldwide Marketing unveiled the iPhone 5s at the media event on Tuesday, he told us that the next generation 64-bit A7 chip that powers it, comes with twice as fast CPU and twice as fast Graphical Processing Unit (GPU) compared to iPhone 5’s A6 chip.
The first benchmark results of iPhone 5s has just hit the web, which confirm that A7 chip indeed comes with twice as fast GPU.
Phone Arena reports that GFXBench 2.5 score of the iPhone 5s confirms that the graphics performance has improved considerably. They also point out since the GFXBench test does not support OPenGL|ES 3.0, which is supported by iPhone 5s’ A7 chip, we may not be seeing the full capabilities of Apple’s new system-on-chip.
In the 1080p off-screen test, the iPhone 5S shows nearly double the performance of its predecessor. This doesn’t show up in the on-screen test though as the benchmark hits the 60fps screen limit (the test is old and can’t stress the GPU at the native 640 x 1136 resolution of the iPhone 5s).
With OpenGL ES 3.0 support on both iOS 7 and Android 4.3 and improving mobile GPUs, we’re about to get a lot of eye candy on mobile 3D games.
We’ll have to wait and see how much more improvement support for OpenGL|ES 3.0 will have on the benchmark scores when the test is updated.
The faster CPU and GPU, along with support for OpenGL|ES 3.0, the latest graphics standard should significant improve the performance of graphics intense apps like games on the iPhone 5s.
