In comparing smartphones, one of the key factors generally looked into is processing power. Indeed, for most users, to which manufacturers agree to, speed is key. So it’s expected for manufacturers do everything just to get ahead of its competition. Samsung, sadly, has done something that borders on cheating when it comes to the processing power of the octa-core variant of its Galaxy S4 smartphone. This specific variant runs on the Samsung-made Exynos 5 octa-core processor and the PoweVR SGX 544MP3 GPU.
AnandTech has recently confirmed that the Samsung Galaxy S4 does a trick that boosts the GPU clock frequency when benchmark apps are running. For the rest of the apps, however, the GPU speed is slower.
Specifically, the GPU clock frequency is somehow boosted to 532MHz when apps like AnTuTu, Quadrant, GL Benchmark 2.5, BenchmarkPi and Linpack are launched while rest of the apps and games get only 480MHz speed. As long as benchmark apps are running, the speed is boosted and it returns to the slower speed for the rest of the phone’s performance. According to tests done by AnandTech, there appears to be a program called “BenchmarkBooster” that’s responsible for executing this trick. There appears That’s not illegal but it’s something that can only be interpreted as cheating since it presents an impression that the phone is running fast based on benchmark tests but in real-world situations, it’s in fact slower.
