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.

    My mother just bought the HTC One and it is just awesome. Got her a case from Amazon and couldn't believe the discounts they have. I'm sharing this with everyone, here's a list of the cases with the biggest discounts and best reviews: http://amzn.to/1ayqnnq. Very Happy. Reply

    It sound weird question but does anyone know if this mobile has dual receiver such that it can measure 2g/3G at the same time without entering compressed mode? Reply

    This is what i just wrote in my facebook timeline when i shared this review..enough said, i guess! :-) "Darnnn, this is probably THE MOST detailed review I've seen on ANY kind of a gadget!! AMAZING ground work and research,Brian Klug!!!" Reply

    oh, btw..this is nothing to do with the gadget in question (HTC One) itself, cos I was already sold on it even before i started reading the review and now i can't wait to lay my hands on it! Reply

    the comparisons between the various phones with the differing angles / zoom etc. make it difficult to understand the true differences. In general the HTC one phones appear nearly as good as the Lumia 920 and in some specific cases much better than the 920. I'd go for the camera on the 920! Reply

    I read a lot of comments about removable battery and SD card and frankly it's a problem that's not really a problem. People always say that removing the battery is a must but most of them never pulled out the battery even once. Let's be honest, it's too troublesome to swap batteries and charge the extra battery vs bringing a powerbank. Expandable memory is a joke to get people to buy 16gb models at the price of 32gb. 32gb is the sweet spot for me with games, movies and music. If I go out on a trip and want to bring a host of hd movies there's the other usb function which basically let's you watch media directly from a flash drive. I honestly don't see how you compare the one with the s4 or even the iphone. They're great phones but nothing that htc one brings to the table with the same buck. It has better screen and sounds. Software and camera is opinionated but you can't argue that hardware wise nothing comes close to it. Reply
