Samsung cheating in benchmarks.
Well, this is more cellphone related. But I thought it was interesting enough.
http://www.anandtech.com/show/7187/looking-at-cpugpu-benchmark-optimizations-galaxy-s-4
Samsung has a command that can check the speed of their CPU at any time as Anand shows.
So when Anand ran their benchmarks, some were running the CPU at 532...the maximum frenquency the chip can run at.
Ok, so I guess you could argue the cellphone just increases the CPU speed when needed.
Hm, not so, since it doesn't seem to be doing that for all benchmarks. So what's going on here.
So Anand poked around the TwDVFSApp.apk file with a hex editor. And low and behold, they're using detection code to detect certain benchmarks and do CPU specific optimisations. It does this for AnTuTu, BenchmarkPi and Quadrant benchmarks.
I'm writing this on a Samsung screen, so keep that in mind. But I'm not shocked that these companies go out of their way to hide and cheat when there are billions involved.

Not doubting your figures at all, but there are 2 versions of the S4, with different main CPU and GPU.
There is the GT-I9500 and the GT-I9505
One is faster than the other graphically, but has poorer battery life, and the other is slower but has a lot better battery performance.
So just in case, it depends on what Samsung quoted for each of the 2 versions.
No real news here. Graphics card manufacturers have been doing this for years with driver optimizations on PCs.
Look at the figures that Blizzard gives out.............
Quix, go get 'em!
