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.

    A native speaker, probably, but it's a hell of a lot harder for people where English is their second language. Reply

    he also has a problem with capital letters you would think that using a shift key wouldnt be too hard since even elementary school children understand capitals but apparently its too easy to get online now Reply

    Well i am going to get the HTC ONE (pre Order UK Orange, probably Wednesday 8th) and see how it goes, i really do like the front speakers but i still think battery mite be an issue but i may be more concerned about the GPS shutting down if the phone gets to hot (like the HTC One X does)

    Guess i can always sell the phone and get the Moto razr HD (or S4 maybe) but it is not much of an upgrade from the RAZR MAXX currently own (mostly faster CPU and little better screen +2600 bat) but i would really want the HD MAXX version (not for sale in UK......) just for the little bit more power to last the day if i have used it a lot, as the 2600 on the RAZR HD should be fine as the phone is not going to be pulling much power compared to S3/S4 or other random HTC phones incarnations

    "if the phone gets to hot"

    What? How do you "hot" something? And why would the phone get to do it?

    The depth of this review is astonishing. Excellent work, Brian. Reply

    Yes, it is. The word 'review' doesn't cut it. It's a comprehensive analysis. This site teaches you more about a product than like the rest of the internet combined. Reply

    This kind of review is why I come to Anandtech. :) Reply

    Too many quality control issues from what I've read around the Web. I would wait out the first batches. Reply

    I have to say that I am really drawn by the build quality and construction detail of the HTC One. Even if the specs of the S4 are marginally higher in certain areas, I prefer a device that feels solid and comfortable to hold. "Ergonomics" doesn't matter for my desktop, but for a cell phone it's almost first priority when all other things (camera quality, screen quality, CPU, etc.) are equal or close to equal on competing phones.

    I'm a Windows Phone user at the moment, but the One is bringing me over to Android. Pre-ordering right now on my carrier's website.
