GPU Benchmark Optimizations in Galaxy S4 could be fake

31 July, 2013 Samsung


AnandTech reveals Samsung is boosting the GPU clock frequency of the Exynos 5 Octa-powered Galaxy S4 that enables the device to achieve a higher score.  Some more digging also revealed whitelisted benchmark apps that when opened, bumped the GPU clock frequency to maximum (532MHz) while rest of the apps and games were limited to use 480MHz.


For those of you who aren't familiar with the Exynos 5 Octa in these devices, the SoC integrates four ARM Cortex A15 cores (1.6GHz) and four ARM Cortex A7 cores (1.2GHz) in a big.LITTLE configuration. GPU duties are handled by a PowerVR SGX 544MP3, capable of running at up to 533MHz.


The CPU of the Galaxy S4 variants was also found to behave somewhat odd with its clock speed forced to the maximum possible the minute you run a benchmark. That's not technically cheating though, as the power is available if needed elsewhere - there's no overclocking.


So, it seems Samsung is trying to polish the octa-core Galaxy S4 reputation. Whatever the reason, we are hoping it doesn't become a habit - the company's flagships have enough power and they don't need to use such unfair practices to gain advantage.
