For a long time, we seem to have a thinking pattern, that is, Android is constantly competing for core and dominant frequency. Apple can achieve or even surpass the fluency of Android's four core or even eight core with only two cores. But we often ignore Apple's GPU. Apple has always been "generous" on GPU. This time It claims that the graphics processing performance is twice that of the iPhone 5, and the GFXBench website already has the performance of the iPhone 5S. Is Apple going to be "silent" again this time?
First, let's take a look at the GFXBench test results of the iPhone 5S. For the time being, there are only two tests of version 2.5. Offscreen (1080P) can reach 56 frames, and Onscreen (original resolution) can reach 53 frames. There are also some "unscientific" aspects here. Normally, the low resolution performance should be higher than the high resolution performance, but the iPhone 5S is the opposite. It is estimated that the CPU frequency is unstable.
However, the GPU model we are most concerned about shows "Apple A7 GPU". It is estimated that the old version of GFXBench cannot recognize the new GPU of the iPhone 5S. However, the OpenGL ES version is only 2.0, which does not reach the widely publicized OpenGL ES 3.0 on Apple's launch conference. It seems that iOS7 is not ready.
There is no suspense about the system information. The iPhone 5S code is iPhone 6,1, and the system is iOS7 with a resolution of 1136 * 640. With such powerful GPU performance, it can be expected that the gaming performance of the iPhone 5S will take another big leap when it is only put on a resolution of less than 720P.
In terms of horizontal performance, we have also collected the performance of some other high-end devices. The following is a comparison chart (here is the Offscreen test item, which only represents the computing power of the GPU. The actual situation is much more complicated due to the resolution involved)
From the above results, the performance of the iPhone 5S is absolutely excellent. Even in the face of today's strongest Galaxy S4 LTE-A, there is little difference. Its performance is at the same level as that of the iPad 4 and the TD Xiaomi 3. The "double graphics performance" officially claimed by Apple has also been basically reflected. Of course, this is just a test score of GFXBench 2.5. We can't make a conclusion so quickly about the graphics processor capability of the iPhone 5S.
The strategy of the iPhone 5S is undoubtedly very smart. With a powerful enough GPU and a low resolution, the game performance will be much better than that of the previous generation iPhone 5. Although Android high-end phones are more powerful in graphics performance, they need to be equipped with 1080P level screens. In addition, iOS game optimization has always been an advantage. It is too early for Android phones to challenge iOS in games. Looking forward to the SoC development of iOS devices, Apple's strategy is to continuously improve the operating efficiency and dominant frequency of the CPU, while the GPU is in a state of crazy "stacking". The next generation iPad will definitely make a big leap in GPU performance, and perhaps we will soon see the emergence of a super GPU twice as powerful as the SGX554MP4.
