Just yesterday we shared that Samsung was caught using sneaky methods to manipulate and inflate benchmark scores on their Galaxy S4 line of phones. A number of tech websites, including the highly reputable Anandtech discovered what seems like an obvious deception. From their testing the SGS4 would increase its GPU clock speed from 480MHz to 533MHz, but it seemed to only do it when running benchmarks like AnTuTu & Quadrant.
Since the revelation was published yesterday, Samsung quickly moved to respond. They began with a very vague initial response, which stated, "[We] did not use a specific tool on purpose to achieve higher benchmark scores."
Later on they shared a slightly less vague denial and posted it on their official website. Here's a quote with their full response,
Their response seems to have some plausibility. The only problem with this denial is that during testing at Anandtech, they could find no other app which used the higher clock speed bump for the GPU. This still leaves things in a grey cloud of doubt. What do you think? Did Samsung doctor the results, or is this just a case of mistaken intention?Under ordinary conditions, the GALAXY S4 has been designed to allow a maximum GPU frequency of 533MHz. However, the maximum GPU frequency is lowered to 480MHz for certain gaming apps that may cause an overload, when they are used for a prolonged period of time in full-screen mode. Meanwhile, a maximum GPU frequency of 533MHz is applicable for running apps that are usually used in full-screen mode, such as the S Browser, Gallery, Camera, Video Player, and certain benchmarking apps, which also demand substantial performance.
The maximum GPU frequencies for the GALAXY S4 have been varied to provide optimal user experience for our customers, and were not intended to improve certain benchmark results.
Samsung Electronics remains committed to providing our customers with the best possible user experience.
