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.

    Good point on the piracy FITCamero, I hadn't thought of it like that but it makes total sense. Reply

    Lack of sd cards has nothing whatever to do with piracy. Reply

    Google has made public statements for years that they prefer contiguous memory and took out sd card support in the latest version of jelly bean so you have to root to get it back. Pretty clear how they feel about it. Reply

    Sd cards are slow and unreliable that's why. Reply

    Kind of screwed if you are on Verizon though and want their coverage. Can't believe they aren't offering this phone. Reply

    Sounds like an absolutely wonderful device but I'll wait the Galaxy S 4 reviews. Reply

    I forgive you for disappearing on us, and becoming so much less active. This review is quite possibly the best phone review I have ever read. Reply

    Commenting as I read
    - wow, that's a lot on the casing. isn't buying a phone for its casing like buying a gift for its wrapping ? Also, who cares ? phones need a sleeve, especially expensive Ones (pun !)
    - "This is what build quality is about, making an actually solid device." Nope. It's about making a resilient, durable design. I suspect Aluminum is bad at withstanding daily use (scratches...), and mishaps (falls). I'd rather have something a bit bendy, with a bit of amortization, and less visible scratches.
    - good sound, at last. Nice !

    It's a bit sad to see HTC misdirecting their efforts (the casing of the HD2 was already very good, no need to get overly fancy), and forgetting the basics: an SD slot, a removable battery, timely updates, a big screen.

    I was sad to not have an upgrade path from my beloved HD2 to another HTC. I'm on a Note right now, and the One is not what I'll be upgrading to later this year. I think HTC went for premium-mainstream, and forgot about the nerds. I wish them well.

    Then go buy an S4 then. You're clearly not the target audience. Reply

    In the end, Android is about choice (well, except in the case of screen size). If you want a premium metal phone, get the One. If you want a plastic phone with a removable battery and SD slot, then get the S4. Reply
