    The Samsung Galaxy S4 runs an Exynos 5 Octa central processing unit with multiple cores and a GPU or graphical processing unit which operates at 480 MHz GPU. In February a forum member at Beyond3D suggested that Samsung overclocks the GPU to 532 MHz while running benchmarking tests that are intended to showcase how powerful the processing unit is, while throttling it to just 380 MHz when in actual use. The folks over at AnandTech recently tested and researched the claims and discovered code that Samsung uses to speed up the processor when (and only when) running popular speed testing suites such as GLBenchmark, AnTuTu, or Quadrant.

    Now some may refer to such a situation as optimization while others might claim that it helps save battery. Most are saying it’s just plain cheating though. The switch seems to have real, everyday consequences as many people make decisions on which device to buy based on performance. It’s not just the GPU either though; AnandTech discovered that the same thing happens with the CPU.

    Certain benchmarking suites such as GLBenchmark, trigger the CPU to jump to 1.2 GHz, while others such as GFXBench, are not triggered and use a default CPU speed with lower performance, at just 250 MHz. Other benchmarking apps trigger different CPU speeds, with Linpack inspiring Samsung to offer up 1.6 GHz and Snapdragon hitting the same heights as GLBenchmark 1.9 GHz.

    The South Korean electronics giant apparently uses a settings application, TwDVFSApp.apk, which includes hard-coded CPU settings for the different benchmarks, among them a “boost mode” that kicks the CPU and GPU into high gear. Trying to game benchmarks is not technically something new, it’s been happening ever since enthusiasts started comparing Apple’s PowerPC processors to Intel’s x86 CPUs. In most cases however, what’s going on is a deliberate attempt to maximize the attractiveness and perceived power of a certain chip while reserving the power for artificial testing situations.

    How do you feel about the whole situation?

    Shame on you Samsung, but this is no where near as bad as eBook price fixing.

    Um, yes it is just as bad as iBook pricing. Samdung has a history of dishonesty, try supporting an American Company you Samdung drones. Or maybe you should go live in Korea. If our dumb *** government and certain citizens would support American companies we would once again be a world leader instead of the laughing stock of the world lately. You American Samdung fans are an embarrassment. I won't spend any of my time reading your dribble, whinny replies. Anti American Fools

    Weather it's cars or iPhones or S4's whatever. Manufacturers are going to bump up the stats - car mpg done at 80kph for example. Do your homework. Talk to owners. Try before you buy and pay little attention to advertising hype.

    Why does it have to be about supporting a company just because it's American? when realistically the company doesn't give a toss about you, only your money.

    Maybe some American companies should step up their game and build an android phone that far exceeds Samsungs rather than blaming Samsung for throwing in quality internals. Or to match the HTC in looks and power.

    Choice is good.

    How about LCD screen price-fixing, which Samsung has been busted on, more than once I think.

    Shame on Samsung, there's a big difference between optimizing and plain CHEATING ... *Points finger in disappointment =|

    ROFL....

    Yea, instead support American company that manufactures vast majority of its products in China and keeps most of its made money overseas so it doesn't have to pay taxes in the US...

    You are truly a smart one!!!

    Most if not all business follow that model^^ Apple is not alone in protecting its assets. What I find funny is that anything Apple does it scrutinized like a murder scene. Samsung could do the same thing and it wouldn't even make the paper hahaha! Galaxy S4 is not outselling anything..in the end its funny not competition

    Samsung employs about 14000 Americans. You go to any major US city (NYC, SF, LA, Houston), they have huge skyscrapers set up. Quit being a dumbass.

    He is, he took a break for a while when I called him out last time. He apparently decided to come back for round two.

    I don't care how many buildings Samsung has or how many people they employ stateside. They are a foreign company and they do not fairly compete with American companies, including Apple. Korean companies, like their Chinese counterparts, are heavily state subsidized. American companies are not. As such, they needn't be as creative or efficient to compete in the marketplace. Try supporting your country for a change.

    US department says Korea violates subsidy rules
    They can have my jailbreak when they pry it from my cold dead fingers.
