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.

    Sad to hear there's already blemished on your device. I thought it's supposed to be sapphire or something which causes the purple haze when directed on bright light source. I read that iPhone5's has the same purple haze because of this, but I don't know. I'm just going to put some kind of protector on the back so the camera is recessed from the rest of the back.

    Can you comment on how the condition of the screen/plastic and aluminum seams are on your device? I read there are some quality control issues. I expected it to be Apple iPhone quality, but maybe it's not up to that level yet. (I'm a Note 1 - N7000 user.)

    Go to HTC's Smartphone page and see how many phones are called the "One" or have "One" in the name.

    SEVEN. SEVEN phones have "One" in the name. What the hell were they thinking? Why didn't they call it the HTC Aluminium or the HTC Ultrapixel? Something that distincts it from the flustercuck of phones it has.

    you want to count how many samsung devices are named galaxy? they are building a brand name, it is the right thing to do. Reply

    They should have named it HTC One Ultrapixel or something. Samsung's Galaxy is the family name, and then there's a model name which makes the distinction. Every time I search for something related to HTC One, I have to do "htc one -v -x -vx -h -evo -z" to filter out everything. It's kinda crazy.

    Anyways, I received my HTC One today and I'm dissapointed at the build quality. What's with the gaps between the screen and the aluminum speaker grill, and one of the corner has a protruding black plastic (which wraps the screen on left and right edge). The sim card eject hole looks like the plastic has been drilled with a electric home drill. I can probably drill it cleaner than that. Maybe I was expecting too much from them. I do like the performance overall, but the quality control really sucks.

    Are you guys going to review the US version with LTE and update the review by any chance? That would be greatly appreciated! Reply

    I second this. I checked out a few at the AT&T store, and the screen, sound and form were gorgeous, but would appreciate a updated review that considers the US models (rather than UK/international ones) with LTE and more importantly updated software (especially for the camera, hopefully).

    Also, I have to say, 3 of the 5 models displayed at the huge AT&T store had a visible slight gap on top and bottom where the white metal strap meets the back aluminium. It was disturbing to see, and I even took a photo, lest I get accused of being a nay-sayer. Personally, I'm guessing this is just first production model quirks, like the first round of Iphone5s having chipped strips on the side, so I'll wait till the more mature batches come along, and hopefully an updated review to help me settle on what to buy too!

    I've become a fan of aluminium body. It was iphone 5 first but now i've fallen in love with the HTC One. The camera is also very impressive and the quad-core processor is more than capable of doing any task that you throw at it. Talking about the octa-core phones, do you really think that you'll really require 8 cores for doing some calculation on a smartphone?
    I've prepared a table of what Samsung has been doing for years and what the Koreans must learn from HTC.

    Are you saying that the iPhone first came out with the Aluminium body, or you liked the iPhone 5's aluminium body first? My HTC Sensation came out in 2011 and it has an aluminium body... Reply

    All bullshit about camera resolution aside this camera is great , AMAZING in daily use. The HDR mode produces great indoor photos. Just captures everything. No black holes or white flares. Great for the average user (me) Reply

    OK, just got home and took a pic out my back window in night mode. Have never been able to get anything but black noise with other cams (albeit phone cams and low end cameras) I wish I could post this pic, amazing! They have achieved their goal of expanding the useful range of the phone cam. Reply
