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.

    Yea I missed you on the last podcast. It just wasn't quite the same without (what I like to call) the "Klug rants." Reply

    i am very interested in this HTC One phone but i am also interested in the RAZR HD maxx as well but it does not seem to be much of an upgrade from the razr maxx i currently own

    issue i have is will it Really last an full day on one charge of real world use, as i have seen a lot reviews of phones and the battery life part of the reviews to me seem an Lie quoting Twice the real world battery life, yours included as well i got the HTC One X (uk) and it was an Joke to use as it would not stay on for long (only one that gets close to correct battery report is the razr Maxx and the Razr HD) only one site seems to side with poor battery life or currant smartphones correctly and that is "theverge" but other sites and other users do not like the site and tend not to agree with there results

    on the razr maxx that i own it can go nearly 2 days or 1 day if i go nuts on it, i really love HTC phones but with the Joke of an phone HTC one X (its like an portable gaming laptop your lucky if it lasts 2 hours on battery) that got rid off in less then an month of owning it, every phone i have had has been poor battery life, i had the G1 and HTC desire (the first one) but i could use an extended battery on them yes it made them an brick but it lasted long time

    i do really like HTC phones but as all other smart phone makers are doing still is neglecting the battery size so it can Just about make it last an day if you use it lightly

    but to add this is an running battery life with any one person i have come across who has got smart phones Reply

    Is the period key broken on your keyboard? Nothing but run-on sentences. Reply

    was bit long my bad, just i find battery tests that sites do seem to be more then half what is reviewed as to why i norm just divide it by 2.3x ish to get real world results

    there needs to be a real world tests as well (facebook, twitter, skype, youtube, browsing so on), as there is no way you can get the times you see on review sites (HTC one X international version and the iphone is good example of unrealistic battery life is when reviewed)

    Interesting that you acknowledged that you had not punctuated your post you then made another post and again you didnt use punctuation it is interesting i was going to ask you why you did it i have decided not to do that that would be redundant i am of the opinion that you are going to continue to post this way as a result of that i am going to disregard your posts in the future .

    at least ieexgx has punctuation in his sentences, anybody should be able to tell when a sentence starts and ends without thinking about it Reply
