Samsung Caught Boosting Galaxy S4 Benchmarks
A recent forum post at Beyond3D made an interesting claim: that the Samsung Galaxy S4's GPU ran at 532 MHz for certain whitelisted benchmark applications, and at 480 MHz for everything else. The folks at AnandTech decided to investigate and found out that the phone does indeed let its GPU run at a higher frequency when particular benchmark software is running. They found a similar oddity with the CPU — it wasn't restricted for other apps, but it was forced to run at max speed during benchmarks. Then they decided to look for direct evidence that this was intentional.
"Poking around I came across the application changing the DVFS behavior to allow these frequency changes – TwDVFSApp.apk. Opening the file in a hex editor and looking at strings inside (or just running strings on the .odex file) pointed at what appeared to be hard coded profiles/exceptions for certain applications. The string 'BenchmarkBooster' is a particularly telling one. ... Quadrant standard, advanced, and professional, linpack (free, not paid), Benchmark Pi, and AnTuTu are all called out specifically. Nothing for GLBenchmark 2.5.1 though, despite its similar behavior."
When every sixth topic on Slashdot is about the evils and perils of Government Regulation, why are we constantly seeing examples of companies misleading, blatantly lying, to their customers? We need more teeth on consumer regulation. I bought my Samsung Galaxy S4 on certain assumptions of power. Remember Hyundai blatantly lying about their fuel numbers for half a decade? They were doled out a punishment, but the boost in sales due to in part by their chain-wide efficiency offset any net losses.
Slashdot readers will remember this, and probably choose an S4 when faced with so few choices. Samsung sees no benefit to not skewing numbers in the future.
Source, proof, evidence or STFU.
No, they don't. There is a difference between optimizing a system and overclocking just for specific benchmark apps. Samsung could get fraud charges on this one if they advertised or published the benchmarked speed. It is less obvious if they did not do the publishing themselves.
No different than how Samsung made tons of commercials poking fun of iPhone users. If you make a better product just show the product. If you make an inferior product then take cheap shots at the competition.
Yep. Apple would never make adverts poking fun at the competition...
No sig today...
That doesn't tally with the information extracted from the S4 code: it lists several benchmark apps, which when detected activate a "boost" feature that changes the CPU clock.
No kidding!!! What do you say at this point?
That's nice. It's still unethical and should be treated as such.
SJWs are the new boogeyman. -Me
I don't think we need to celebrate benchmarking phones, period. This was one of those flamebait trolling things that happened in the PC era where people boasted how superficially fast their beloved shoebox was by putting $10k worth of equipment into and liquid cooling it just to get some high number result in 3D Mark or some other meaningless program.
We don't need this for phones.
Yes phones play games, yes phones are getting faster, but realize that phones and tablets are a HUGE step back from the PC era in terms of performance so benchmarking them means you may as well drag out your dusty Pentium era PC and start boasting about good its benchmark numbers are.
Also when 80% of the apps on the Android platform are unstable POS then I don't care about how fast they crash. Even Chrome quits unexpectedly repeatedly and this is by the company that makes the Android platform on their own Nexus brand devices.
I haven't thought of anything clever to put here, but then again most of you haven't either.
