Samsung speaks out against allegations of benchmark-rigging

Less than a day after Samsung was said to be using tweaks to make the Galaxy S4 score higher in benchmarks (by increasing the clock speed of the GPU when a benchmark app is launched), the company has officially responded to the allegations, saying that they are not doing anything suspicious to make the device stand out in benchmarks.

Here’s the statement they provided:

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.

We remain committed to providing our customers with the best possible user experience.

Well, it does make sense to allow full screen apps to take as much power from the GPU as possible. However, code was found specifically mentioning certain benchmark apps that get the higher GPU clock, something which Samsung didn’t address in its response, so we’re not sure we believe the company in this case.

But anyway, if you enjoy using your device, then these benchmarks don’t ultimately matter, though it would be great if Samsung could come clean and let their devices be known on their real-life merits, instead of going around tweaking stuff to just get better scores in reviews.

How is this different from the boost technology in an i7? The one that only activates in a select few programs, primarily benchmarks? You never use the 3.4Ghz an i7 supposedly gets, either.

That said, it’s still rather silly to limit the clock speed on everything but a benchmark.

However, if they don’t limit it for 95% of the time, people are undoubtedly going to whine about how much less battery life they’re getting whilst playing Farmville.


It looks like some of samsung’s own apps use the higher GPU clock speed


Wow… lie much? I don’t see a ton of things that get to use 533 MHZ other than the benchmarks. This is outright deception. The phone doesn’t run at 533 MHZ, it shouldn’t test like it does. This amounts to false advertising, plain and simple. Shame on Samsung for trying to legitimize this.


Sadly it can’t be considered false advertisement when the GPU frequency was never published. As much as i hate to see this type of “deception”, they never promised any benchmark scores, frequency, or performance
