Samsung has issued a formal statement denying allegations that it has tweaked the hardware of its Galaxy S4 devices to perform better in several benchmarks.
In the press statement, Samsung asserts that the maximum GPU frequencies for the Galaxy S4 have been varied to provide the optimal user experience, and were not intended to improve certain benchmark results.
The company claims that the maximum GPU frequency of 533MHz is applicable for running apps that are usually used in full-screen mode such as its S Browser, Gallery, Video Player and certain benchmarking apps. For certain gaming apps that may cause an overload when used for long periods of time, Samsung states that the GPU frequency is lowered to 480MHz.
It is important to point out that Samsung has failed to address the discovery of strings of code that target specific benchmark apps for higher clock speeds. AnandTech carried out an investigation after a forum member of Beyond3D discovered these abnormalities while conducting GPU overclocking and voltage control. These optimizations apparently gave the Exynos 5 Octa and Qualcomm Snapdragon 600 models of the Galaxy S4 an estimated 11% boost in benchmark performance.
