As previously reported , the resource AnandTech revealed the fact of increasing the frequency components of the processor Samsung Exynos 5 Octa in the smartphone Galaxy S4 during the running test applications.
In particular, the operating frequency of the GPU when doing normal daily applications of 480 MHz. However, if you run the test applications it goes up to 533 MHz. Thereby providing some performance gain, but it is only visible in the tests, but not for daily use smartphone. Similarly, behave and computational core processor. During the execution of applications GLBenchmark 2.5.1, AnTuTu, Linpack and Quadrant them to function at a higher frequency than when the application starts GFXBench 2.
Samsung has quickly responded to the information and denied the accusations in an artificial increase in processor performance for test applications. It is noted that the company does not use special means to achieve higher results in test applications. Additionally it is reported that in normal conditions the frequency of the GPU chip used in the smartphone Galaxy S4, may rise to a value of 533 MHz for maximum performance. In this full-screen applications are classified as those that require the maximum available capacity. These include, for example, applications to work with the camera, browser, gallery, video player, as well as a means to measure performance. At the same time, many games do not require maximum performance on the job.
Samsung does not react to the statement AnandTech that the firmware is present in the code list of test applications that provide improved performance. However, AnandTech notes that some of the test applications that are not directly specified in the code are also associated with increased frequency.
