Samsung has been caught in the act of optimizing CPU/GPU performance in certain S4 benchmark apps. It is guilty of trying to influence reviews by boosting Galaxy S4 benchmark results.
The GPU in different versions of the flagship Samsung Galaxy S4 was performing in record time. This is evidence, if any is needed, that Samsung is giving the fillip to its Galaxy S4 according to AnandTech. The international product employs a Samsung Exynos 5 Octa system-on-chip. There are various benchmarking apps too. These include the following three: GLBenchmark 2.5.1, Quadrant and An Tu Tu. Meanwhile, the GPU whirrs at 532 Megahertz. The gadget however is usually fixated at 480 Megahertz. It is precisely this difference which offers a visible boost in performance that amounts to 11%. As for the CPU performance in both the Exynos and Snapdragon Qualcomm models, it is also changed. This causes the processor to jump to the topmost performance mode and remain stuck there in spite of the actual workload.
The only problem is that benchmarks have a flimsy relationship to how things work in the real world. The benchmarks inside the Galaxy S4 models were especially selected for exclusive treatment in software so as to increase the scores. And the funny thing is this doesn’t help the customer one bit in real life situations. This is rather like the athletes doping before a contest or event. In other words this is not just electronic wizardry but a whole lot of trickery. What matters is how the device works in actuality, not what specific benchmarks it displays. Samsung has been caught red handed and has no explanation for its devious ways.
