The Samsung has allegedly optimised its flagship smartphone, Galaxy S4, to achieve more scores on the benchmarking tests.
Hardware testers at AnandTech, a website that keeps tracks of technology and computer hardware trends, have found that Galaxy S4 identifies some benchmarks and artificially boosts the speed of the processor to obtain better results.
Samsung came up with the Exynos 5 Octa (5410) 8-core processor based Galaxy S4 that also landed in India.
This chip combines four ARM Cortex A15 cores (can be clocked at 1.6 GHz) and four ARM Cortex A7 cores (can be clocked at 1.2 GHz) in a big.LITTLE configuration. The PowerVR SGX 544MP3 GPU is capable of running at up to 533 MHz speed. While launching the handset Samsung did not clarify the maximum speed the GPU can achieve.
AnandTech found that Samsung includes several system files in Galaxy S4 that contain references to popular benchmarking apps. This means the phone identifies those benchmarking apps and creates special conditions to run them. Similar hardware capabilities are not available to consumers when they are using the device.
The report also mentions that Samsung includes a code referred to as “BenchmarkBooster” that essentially trigger the phone’s hardware to run at a higher clock speed when benchmark tests are run.
While this is one device that has been caught, but it is plausible that other manufacturers may have been doing something similar.
