Samsung Deliberately Rigs Benchmark Results of Octo-core Galaxy S4
Although benchmarks can give us rough estimations on performance levels, others believe that they are a waste of time. Benchmark results don’t always translate well to real-time performance and they can be easily manipulated or faked. We recently received reports that Samsung deliberately rigged results of popular benchmarking tools by boosting the hardware performance through “unusual” means.
A number of hardware experts spotted that some benchmark tools behaved rather oddly when they tested the Galaxy S4 with Exynos octo-core processor. After a more thorough analysis, it is believed that the Galaxy S4 variant comes with a specific code that boosts the processor and GPU to higher clock rates when they are benchmarked.
As an example, during a benchmark test, the GPU speed jumps to 532MHz from the original clock rate of 480MHz. The octo-core variant of Galaxy S4 seems to overclock automatically when users run Quadrant, Linpack, Benchmark Pi and AnTuTu, all are popular benchmark tools. It’s worth noting that although the 52MHz boost in clock rate is noticeable in benchmark results, it is far less perceptible for average users, except for the increased heat buildup and shorter battery life.
