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.

    I look forward, therefore, to never seeing one awarded. Reply

    Yeah for me at least, platinum would imply absolute perfection.

    Correction: Diamond, followed by Masters/Grand Masters is higher than Platinum. #Starcraft Reply

    lol! yeah, diamond after platinum! that will be the phone that survives the "Blender test"! Reply

    Wait, what?! You should REALLY add "spoiler" tags to your comments, man. Ha ha, jk. But I've never seen an Anandtech smartphone (or tablet) review EVER give out an Editor's Award. Wow. Reply

    Yes, the new Awards Tiers include the "Pig Iron" award, specifically created for the Pantech Jest review. And Brian this review was riveting. No shit. Reply

    I must say, I feel pity for those who'd buy the Galaxy S4 over this. This is one gorgeous device, and also goes head to head with Lumia 920 in imaging! Reply

    I'm a Nexus 4 user here, and I'm not going to upgrade any time soon, but I think that consumers will be pleased no matter which of the two "flagship" phones they choose (HTC/Samsung). They both look pretty solid. Reply

    Some would have to, because of carriers. Reply

    I pity the folks who'd buy inferior hardware because of design, finish, etc etc that they'll have under a case forever anyway. Reply
