GPU Performance

Both CPU and GPU clocks are higher on Samsung's version of the Snapdragon 600 (APQ8064AB). While the Snapdragon 600 used in HTC's One (APQ8064T) features a max GPU frequency of 400MHz, in the Galaxy S 4 the max frequency moves up to 450MHz. The increase in max frequency alone is modest (~12.5%), but the gains in GLBenchmark are far more pronounced for whatever reason.

As always, we'll start with low level analysis beginning with GLBenchmark's fill rate test:

GLBenchmark 2.5 - Fill Test

GLBenchmark 2.5 - Fill Test (Offscreen 1080p)

Interestingly enough, fill rate is actually lower than on the HTC One. With so many variables at work here it's difficult to say exactly why this is, but the lowest hanging fruit is to blame it on memory bandwidth differences. Without getting inside the Galaxy S 4 (or more extensive poking around) it's unclear what speed Samsung is running its memory at, which could explain the differences here. We tried tossing the Galaxy S 4 in the freezer and re-running the test but performance didn't improve substantially. Note that GLB's fill rate benchmark is the only one that did not show the Galaxy S 4 ahead of HTC's One in raw performance.

GLBenchmark 2.5 - Triangle Texture Test - Fragment Lit

GLBenchmark 2.5 - Triangle Texture Test - Fragment Lit (Offscreen 1080p)

The low level triangle tests all show significant performance gains over the only other Snapdragon 600 based phone we have (HTC One). Again, I'm not really sure what's going on here with APQ8064AB but the gains here are greater than what clock speed alone can be responsible for. Samsung could be running at higher GPU frequencies more aggressively than HTC or it could have software advantages (a newer Adreno driver perhaps?) or there could be more to this APQ8064AB mystery than we realize.

GLBenchmark 2.5 - Egypt HD

GLBenchmark 2.5 - Egypt HD (Offscreen 1080p)

Egypt HD delivers a fairly sane number however. The Galaxy S 4 manages to outperform the HTC One by around 17% here. Again it's unclear why we're seeing greater performance than clock scaling alone would provide but the net is that the Galaxy S 4 does deliver better GPU performance than other Snapdragon 600 based devices today.

    Why did you use the 3rd gen ipad instead of the current model? Just because than Apple would have been at the top of every GPU chart? Reply

    What, no 3G, 4G and wifi comparative data bandwidth tests? Communications power is a big part of the things "raison d'etre" ! Reply

    Hi,

    I have problem with wifi connection at some hotspots and hotel rooms.
    I was told IPhone and IPad wifi power are not strong comparatively with Samsung or other android phones.

    Is it true ? Are there any official test or comparisons done.
    If there is, please provide website links.
    Thanks

    My current model is IPhone 5 and IPad Mini.

    Are there any official test or comparisons done.
    If there is, please provide website links or email to me: davidsegar77@yahoo.com.
    Thanks

    I was told Iphone / Ipad battery last longer due to the weak wifi power. is it true ? Reply

    I know this is years late, but my S4 is utilizing an IMX135, not an IMX091. Reply
