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.

Many users use the test applications to compare the performance of their devices with other solutions. However, not always test results will reflect the actual performance for regular applications.

Thus, the resource AnandTech as a result of tests found that the mobile processor Samsung Exynos 5 Octa in the smartphone Galaxy S4 operates at a higher frequency 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.

Additionally it is reported that in the firmware smartphone Galaxy S4 was discovered quite an interesting piece of code, called BenchmarkBooster. He points to the mobile device increase the operating frequency when running certain (test) applications.

There will also be used architecture big. LITTLE – 4 cores for background and simple tasks and 4 cores for “heavy” games and applications. However, compared with the increased clock frequency of 5410 – from 1.6 to 1.8 GHz in the “core” Cortex-A15 nuclei and from 1.2 to 1.3 GHz with Cortex-A7.

The second major change is the graphics. The new six-core chip is used accelerator ARM Mali-T628, which gives a two-time increase in power compared to the graphics chip Exynos 5410. The accelerator supports both OpenGL ES 3.0 and Full Profile Open CL 1.1.

5 Octa Exynos 5420 supports displays with resolutions up to 2500 by 1600 pixels, Full HD Wi-Fi displays, Full HD video recording and playback video at a resolution of 1920 x 1080 pixels at 60 frames per second. It uses a dual-channel memory LPDDR3 with frequency 933 MHz and a transmission rate of 14.9 GB per second.

Samsung says that the mass production of chips will begin in August. This is almost a direct confirmation of the fact that this processor will be the “heart” of new GALAXY Note III , announcement will take place at the end of August or beginning of September. Recall that the first generation eight-core Samsung Exynos processor was presented shortly before the presentation GALAXY S4.
