Samsung replies to benchmark cheating accusations, doesn't apologize, lies instead.
From Samsung's blog earlier today:
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.
Following the claim that various built-in apps can also unlock the full frequency just like benchmarks, Anand ran various tests to verify if that was true.
And guess what the outcome was?
Samsung claims however that a number of its first party apps (S Browser, Gallery, Camera and Video Player) can also run the GPU at up to 532MHz
As we mentioned in our original piece, there's a flag that's set whenever this boost mode is activated: +/sys/class/thermal/thermal_zone0/boost_mode. None of the first party apps get that flag set, only the specific benchmarks we pointed out in the original article.
Samsung's pre-loaded apps can send boost intent to the DVFS (dynamic voltage and frequency scaling) controller, but they don't appear to be given the same thermal boost ability as we see in the benchmarks.
So basically, Samsung is denying overclocking purposely to boost benchmark numbers, and act as if it was the normal behaviour for a bunch of different applications which happen to include benchmarks. And they thought the same people who discovered Boost Mode in the first place would fall for that stuff and not verify by themselves. Ha.
