found to be in Galaxy S4 benchmarks

Cue the Lance Armstrong and Alex Rodriguez jokes, has been caught using performance-enhancing to beef up the Galaxy S4′s test scores. It’s been discovered that the tech gianthas programmed the handset to incrse its clock speed during certain benchmarks.The claims were initially made in the forums of popular 3D graphics site Beyond3D, and have since been confirmed by the hardware specialists over at AnandTech. The S4 specifically enables full speed GPU during testing, and then reverts to slower speeds for everyday usage…Here’s the original claim fromBeyond3D:“I’m currently doing GPU overclocking and voltage control in the kernel for the 5410/i9500 and was screwing around with what was supposed to be a eric max limit only to be surprised by what it actually represents.This GPU does not run 532MHz; that frequency level is solely reserved for Antutu and GLBenchmark* among things. The GPU on non-whitelisted appliions is limited to 480MHz. The old GLBenchmark apps for example run at 532MHz while the new GFXBench app which is not whitelisted, runs at 480MHz. /facepalm”So essentially, theExynos 5 Octa (5410)SoC in the international version of the Galaxy S4 has a 533MHz GPU clock that’s never used. The handset runs apps and games at 480MHz, likely due to battery life and other compromises, but switches to 533MHz for certain benchmarks.Here’sAnandTech’s findings:“Running any games, even the most demanding titles, returned a GPU frequency of 480MHz – just like@AndreiFalleged. never publicly claimed max GPU frequencies for the Exynos 5 Octa (our information came from internal sources), so no harm no foul thus far.Firing up GLBenchmark 2.5.1 however triggers a GPU clock not available elsewhere: 532MHz. The same is true for AnTuTu and Quadrant.”And what’s worse is the site found thesame behavior (on the CPU side) in Qualcomm versions of the Galaxy S4, as well as other processors. This seemingly indies that isn’t just on benchmarks for one handset, but it’s more of a widesprd company policy.So why does any of this matter? Well for starters, it’s very mislding. What if someone were to compare benchmark scores on multiple handsets, and buy the S4 based on it coming out on top? Or what if you bought it thinking it could handle graphics-intensive tasks, and it couldn’t?What needs to do is start opening up these higher GPU speeds to all apps/games, or stop using them to game test scores. It’ll be interesting to see what, if anything, comes of this discovery and if any other handset makers, like , are guilty of similar behavior.What do you think, is this a big dl?
