Snapdragon 600 - GPU Performance

On the GPU side of Snapdragon 600 we're still looking at Adreno 320, which is easily Qualcomm's first highly competitive GPU. At its launch, Qualcomm claimed the Adreno 320 clocks in Snapdragon 600 could be higher than what we saw in S4 Pro/APQ8064. To find out, we turned to our trusty GLBenchmark suite.

The good news is that none of the thermal throttling we saw on the APQ8064 based Nexus 4 was present on the HTC One. Curiously enough, the thermald.conf file is now stored as a binary file - which means we can't get direct access to it. Either way, although the One can get warm during heavy CPU/GPU workloads, it doesn't throttle while running GLBenchmark which meant our freezer can remain on food cooling duties for this review.

GLBenchmark 2.5 - Fill Test

Here we see a small increase in fill rate compared to the Nexus 4, roughly 14%.

GLBenchmark 2.5 - Fill Test (Offscreen 1080p)

The beauty of being on a 1080p display is that GLBench's on and offscreen tests produce roughly similar results as they are both run at 1080p. The offscreen results do have vsync disabled though.

GLBenchmark 2.5 - Triangle Texture Test

Very similar triangle throughput to the Nexus 4, and a bit lower than the Nexus 4 freezer test, which implies that Qualcomm is doing a better job of keeping GPU clocks under control in Snapdragon 600.

GLBenchmark 2.5 - Egypt HD

The "game" benchmarks in GLBench give us a good indication of overall performance. The offscreen results are most interesting from drawing comparative conclusions:

GLBenchmark 2.5 - Egypt HD (Offscreen 1080p)

The One is fast - it's now the fastest smartphone we've ever tested in the Egypt HD offscreen test. The margin over the Nexus 4 however makes me believe that we're talking about very small increases in GPU frequency at best (either that or better thermal management).

GLBenchmark 2.5 - Egypt Classic

GLBenchmark 2.5 - Egypt Classic (Offscreen 1080p)

The Egypt Classic results are equally impressive. Here we're seeing about a 12% increase in performance compared to the APQ8064 based Optimus G, so at best we may be talking about a 15% increase in frequencies - or again, just better thermal management (or a combination of the two). Given the fact that process node hasn't changed at all, I think a small clock speed boost wouldn't be unreasonable to expect from the 600's Adreno 320. It's very clear that thermal management has improved though.

    The Samsung is smaller despite a larger display. A 4.7" phone is not more comfortable if it is larger than a 5" one.
    Even if you don't care about the removable battery, it is larger in the SGS4 so it will last longer.
    Also while I understand that some people prefer the look of metal, plastic is more practical as it is lighter and absorbs shock better. So plastic is better build quality.
    And I will wait for reviews about the SGS4 before telling which one has the best camera.

    So you won't wait for the reviews and eventual drop tests to see which is better between the two for battery and build quality?

    Also larger battery does not always mean last longer (as is also mentioned in the review; it comes down to software optimization, hence why the iPhone generally does better with considerably smaller batteries). Especially with a higher clocked SoC it might not be 'better,' as you've expected.

    I'd be surprised if the SGS4 garners any sort of Anandtech Editors Choice award. While HTC is actually making functional improvements in terms of how they think hardware and software for a phone Samsung just throws horsepower. I hope the One sells well enough for HTC, b/c this is the phone all other manufacturers should be striving for.

    Of course it's more comfortable, especially because the biggest issue with phones is not the size in every dimensions, the problem is width, and the S4 is wider than the HTC ONE.

    "it is larger in the SGS4 so it will last longer" Is just false. Especially considering how inefficient AMOLED is while displaying whites.

    "And I will wait for reviews about the SGS4 before telling which one has the best camera." I don't need to. The S4 will take better pictures when there's plenty of light, and it will be abysmal when there's no light.

    Turns out the larger battery in the S 4 doesn't last longer. Also if you had read the review you are commenting on you would have seen Brian say the same thing. Reply

    Samsung users need a removable battery because they need to force reboots of the crappy Touch Wiz UI. Reply

    Newsflash..not everyone uses a case or wants one. Its a pretty pitiful comment that cheap plasticky phones don't matter because you can slap a plastic case over the existing plastic. Smells like rationalization. Reply

    Not everyone uses cases and who has inferior hardware. Reply

    I am surprised why folks don't care about SD card expansion at all. For big media consumers, that can be huge. I was constantly hitting the wall on my 16 GB iPhone. It was extremely annoying and not much I could do about except delete my music ir apps. After moving to a Motorala Razr + 64GB micro SD card, it hasn't been the same since.

    Though this one is super awesome and would love to get it, the horror of running out of space all the time stops me. Thoughts ?

    you do know this phone come with 32 and 64GB right? then you can buy a USB-OTG cable and connect any 64GB or 128GB usb stick to it as you like. This is better because you don't have to take the back cover in/out constantly.

    In my opinion, 64GB internal on the HTC one is way faster performance compare to 16GB s4 with 64GB sd card everyday.
  • therealjoshhamilton - Saturday, April 06, 2013 - link

    It's not just your opinion, r/w on internal was 19/14mbs on the galaxy s, class 10 sd cards are stuck at 10mbs (and that's if you shell out the money for class 10). Reply
