Samsung Galaxy S 4 Review - Part 1
by Brian Klug on April 24, 2013 12:01 AM ESTGPU 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:
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.
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.
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.

No plastic and AMOLED which SUCKS.medi02 - Sunday, April 28, 2013 - link
Never heard something as idiotic.Samsung's AMOLED is the reason I don't even consider other manufacturers.

Until you get it in direct sunlight. AMOLED definitely has it's limitations.Belard - Saturday, April 27, 2013 - link
I find the HTC One a truly exciting design compared to the SGS4... The cheap plastic look and feel of Samsung is why I bought the AtrixHD instead (same feature set, but crappy camera) as it looks different and looks better. The HTC feels like a well made product... looks great all over.But why it MAY NOT matter how the Samsung looks is for people who ALWAYS puts an external protection case over their phones, so with the HTC One & iPhones - you don't get to see sign industrial designs that make them sexy and made the purchase... silly, isn't it?
So... for the case protectors, it doesn't matter.
I like my phone to be as small as possible... I don't use them... and so the HTC One will matter more. Also, all that touchwiz stuff is... kind of ugh.

I love Anandtech, and in particular Brian Klug's excellent and objective reviews. If you really want to know all about a new phone, it really is THE place to come and read. I assumed others would feel the same, but NO, there seems to be the same infantile nonsense on here as on other sites. Why do people get so fixated with people's phone choice? As I pointed out on another site, both of these phones are capable of explaining the sum of human knowledge to you almost instantly. they take pictures, they can direct you anywhere, they play music and HD video. In short they are probably the most amazing thing ever created in the whole of human history. And yet people make infantile remarks over whether one is plastic or metal?!MarkHunt - Sunday, April 28, 2013 - link
Have to say it, but majority of the new Chinese Android quad core phones do nearly everything the S4 does for a pittance for a similar performance level. The build quality of the S4 looks no better either.medi02 - Sunday, April 28, 2013 - link
Exactly how much does Samsung save but not using metal cover?Is it really more than couple of bucks?
PS
Got Samsung's first Galaxy S (9001).
About 2 years old.
Never used any kind of protection for it whatsoever. I bet most people whining about it being plastic would use some protective cover on it anyway.

"Most users admittedly don't care however and just see "bright" colors."Uhm, check any pro-sumer camera out there, which of them does NOT oversaturate taken pictures in JPEG mode?
This can't be a hardware fault, can it, after all, RAW looks fine.
So the only reason they oversaturate is because MOST CONSUMERS ACTUALLY LIKE IT THAT WAY. Models that use TFTs can't go as far, since, well, you know, cough, they are actually inferior to AMOLEDs, cough...

And finally the Galaxy SIV has been launched in India for INR 41500 which is a bit expensive but it is well under the asking price for the 16GB version of iPhone 5 16GB and HTC Butterfly.People in India who are planning to buy the S IV should also be aware of the other alternatives close to 40k INR. http://goo.gl/MbJ95
