Hardware evaluation sites Anand Tech Samsung Galaxy S4 exposed on fraud in the hardware test, the test scores higher than the actual value, questioned Samsung on next-generation products are also used in the same means the phone scores were inflated.
Recently a hacker from Luxembourg on the network published a report questioning Samsung Galaxy S4 hardware testing improves the phone's clock speed, Ga laxy S4 in the test scores to get a false result. Well-known hardware site Anandtech subsequent evaluation and Beyond3D tested on Galaxy S4, Samsung confirmed to run sub-test tampered with over the actual operation of the high clock test results obtained inflated.
Galaxy S4 equipped with Samsung's proprietary Exynos 5 Octa processor, AnandTech site Anand Lal Shimpi and Brian Klug on Exynos 5 Octa tested, Exynos 5 Octa quad-core 1.6GHz Cortex A15 + Quad-Core 1.2GHz Cortex A7's big. LITTLE architecture, GPU frequency of 533MHz. In actual use, the CPU will be underclocked situation in order to save power, while the GPU frequency is limited at 480MHz or less. As a professional software to run sub security Bunny, GLBenchmark 2.5.1, AnTuTu, Quadrant and other tests, Exynos 5 Octa's clock automatically increased to 532MHz.

Samsung used this method of fraud is called white list method, the Samsung Galaxy S4 system files, set a white list, including several current common speed software, namely the use of these software testing performance when the processor main frequency is no longer limited to test out the results represent performance than users in the actual use of the product performance. Anandtech speed using two software Galaxy S4 test, one is included in the whitelist An rabbit, the other is not in the list of columns in the white Epic Citadel, over Chengzhong An rabbit in the test is shown in full 533MHz frequency operation, while the Epic Citadel is displayed 480MHz. Except in the whitelist application runtime are reduced frequency and low-frequency operation, run points not represent Galaxy S4 actual performance.
According to Anand Tech estimates that Samsung Galaxy S4 run points higher than the actual value of at least 10%, a mobile phone equipped with eight-core processors also need to please the consumer fraud, showing that the current high-end smart phone market, intense competition, although the test results can not be directly represented phone performance, a variety of hardware specification data so that consumers are confused, the test results for the user's persuasiveness is still very high in this system files are also other codenames, Samsung may use this approach to obtain false score is not the first time.
