Samsung Rigging Galaxy S4 for Benchmarks?

Samsungs newest Galaxy S4 smartphone has been very impressive in benchmark testing.  With it’s Exynos 5 Octa 5410 cpu, it should do well.  The device actually has two quad core processors, one a Cortex A15 running at 1.6Ghz, the other a Cortex A7 with a speed of 1.2Ghz.  Using big.LITTLE ARM technology. it switches between cores based on load needs.

In what has turned out to be something of an embarrassment for Samsung, it appears the device is coded to run at it’s highest cpu/gpu frequencies during benchmark tests, but lower speeds for almost all real-world usage.  The PowerVR SGX 544MP3 gpu, rated at 533MHZ, was actually found to be running at 480MHZ in nearly every game or app that wasn’t a benchmark test.  That’s about a 10% difference in performance.

Anandtech found an apk which specifically had certain applications targeted for the boosted speed mode.  These include Quadrant, linpack, AnTuTu, and Benchmark Pi.  So what does Samsung have to say about this?

 

“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.”

I can’t imagine how the phone knows “certain gaming apps”  from other apps using full-screen mode, and if a benchmark app demands substantial performance, doesn’t that apply to certain games?  Very confusing, and it looks like Samsung is trying to make the device appear better on paper than in actual usage.  Many people use benchmarks to compare devices, and if this can’t be trusted(actually I never would rely solely on benchmarks)  the best thing to do is wait for reviews, or go down to a store and try one yourself.
