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%.

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.

    Well that tough to change battery is a bit of a worry. And the iFixit guide is not very reassuring.
    So one would hope HTC will offer battery replacement services?
    Do they comment on this?

    When you battery wont hold a charge to your satisfaction, drop the phone in the toilet and make a claim on your insurance. That's how the iPhone crowd rolls. Reply

    What insurance? Does HTC confirm to have it 100%? Reply

    IJudge, it seems nothing like a sponsored review please give anandtech some integrity.

    Anyone who is worried about the sealed battery they usually just replace the phone rather than the battery. Also anyone who is that worried about not having a replaceable battery just take out a small battery charger which isn't much bigger than a replacement battery. Great review and a great phone.

    Good point, I have a Galaxy Nexus and never replace the battery. It is always easier to hook up a charger, or external battery pack than to pull of the case, then back of the phone, which could lead to dropping it or worse. Reply

    Can anyone say if this phone has a clearcoat type finish? I would guess it does but I am going to take some PPG Eldorado aircraft paint remover, tape of the area around that "Beats" logo and remove that shit. It will not damage Aluminum (or Aluminium). I really do not want to carry around an $800 sandwich board for Dr Dre. Reply

    Fantastic exterior accessories. As good as ours, I bet. Reply

    I have a lot of respect for the writers on this site as well as their podcasts. These are real technical writers who go the extra mile to provide a complete analysis. This review will go a long way on determining my next phone. I hope they provide a comprehensive report on the Samsung S4 as well. Sadly, am I correct to believe this will not be offered by Verizon?

    Verizon has so far said that it's not planning to carry the One, but there's been conflicting talk on that front. One theory is that it's repeating a 2012 strategy of demanding a custom device, or else waiting for another device timed for later in the year (a la Droid DNA). Reply

    Verizon will get the HTC One Droid Razer Maxx HD in sucker blood red with a SD slot and a extended replaceable battery.
    Of course, the screen size will have to be reduced to allow for their carrier branding.
