Want to know how much frames per second (FPS) does your games run on your Android device? Well, there is a free an application that can do so. GameBench is the one. It can provide detailed CPU, GPU performance and battery analysis on Android devices. So that you can identify the bottleneck of the game or application. By the way, root access is required. Don’t have? No worry, one-time PC connection setup can solve it.

Do you overclock smartphone GPU?

Samsung was caught cheating on Samsung Galaxy S4 GPU benchmark? Well, I don’t care if its PowerVR SGX544MP3 GPU (GT-I9500) can handle higher clock speed. As long as it does not overheat, I am fine since I get better 3D performance. Right? Wow… Galaxy S4 GPU really can run at higher clock speed than the default 480 MHz compare to previous generations. Galaxy S2 and S3 GPU can’t overclock much. Here are 3DMark benchmarks that I ran on Galaxy S4 – both Ice Storm normal and extreme mode. CPU stays on default setting while GPU overclocks at 700 MHz.

How to undervolt Galaxy S4 GPU?

Play lot of 3D games with your Samsung Galaxy S4? Undervolt Galaxy S4 GPU will help to improve battery life a bit. And make it cooler too (not much of course). GT-I9500 PowerVR SGX544MP3 GPU is powerful enough for most of the casual 3D Android games in the Play Store. GPU will auto scales to higher clock speed when more 3D processing power is needed. You can underclock GPU to save battery but that will decrease 3D performance as well. Impact gaming experience is not what we want here. So undervolting is another solution.
