After a couple of tests run by the Ars Technica, it has become clear enough that Samsung devices running the Android 4.4 no longer have the ability to boost the CPU speeds
Looks like we all have it figured out by now that till last year Samsung was showing some artificially inflated benchmark scores but they have now been patched. Ars Technica has been running a few tests recently and the results of these tests clearly indicate that those Samsung devices which are running the Android 4.4 no longer have the ability to boost the CPU speeds during the benchmark tests.
In July last year we had seen the Exynos variants of the Galaxy S 4 and Note 3running their CPUs at an unsustainable max speed during benchmark programs and this boosted their total score by a whopping 20 percent. Yes you read that right, 20 percent. That's how much of a difference they can make. Samsung was supporting this saying that this was pretty normal because varied processor frequencies were designed to provide an "optimal user experience." Whether this phenomenon or concept explained by Samsung is a feature or not, we still dont know.
