Samsung has denied allegations that it gamed early benchmark tests of the Galaxy S4 to make it appear faster than it actually is.
The allegations stemmed from an investigation by AnandTech, which reported uncovering evidence suggesting Samsung was manipulating the Galaxy S4's GPU and CPU operating frequency to yield higher than accurate benchmarking scores.
"The CPU is set to the maximum CPU frequency available at app launch and stays there for the duration, all cores are plugged in as well, regardless of load, as soon as the application starts," AnandTech explained.
AnandTech claimed it noticed the trend on both the eight-core Exynos 5 and quad-core Qualcomm Snapdragon powered Galaxy S4 models.
However, Samsung said the allegations against it are misguided and the changing GPU and CPU settings are designed to improve overall performance, not game benchmarking tools.
"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. We remain committed to providing our customers with the best possible user experience," it said.
The company did not deny that the S4 boosts performance when "certain benchmarking tools" are open, though.
"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," it explained.
"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 Samsung Galaxy S4 was released in April, with its processor speed being marketed as a key selling point. The tactic worked and the S4 has become Samsung's fastest-selling handset to date, storming past the 10 million sales milestone a mere month after launch.
