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.

    In no way Class 10 SD cards are stuck at 10MBps. That's just the minimum.

    I'm simply not buying a non-expandable phone. The same with battery. I'm not the kind of person who changes devices every two years. I just had an iPhone 3G battery die on me and I swear I'm never going to experience that again. In a couple of years, 128GB very fast SD cards will be cheap.

    I also dislike physical buttons. I think Google is right putting them inside the screen and both Samsung and HTC are wrong putting them outside it.

    Finally, all this trouble to get through metal seems pretty silly to me. Coloured polycarbonate (Nokia N9-like) is my first choice regarding materials.

    I'm definitely no the target for this phone.

    xperia ZL has a micro-sd slot and has on screen buttons :) Reply

    On-screen buttons suck because you have to look at the screen and poke at them, whereas physical buttons can be felt and operated without looking. Reply

    HTC just released the One here in China. It's exactly the same awesome phone but has a removable back with dual-sim card and SD-card slots. I still use my 2007 iPhone with its original battery and it still works fine. I love my Nokia Pureview 808 with it's lovely and tough polycarbonate (plastic) body. The plastic of Samsung phones is real cheap-looking and crappy, and easily damaged. I had a Samsung Note that I got rid of whilst still keeping my antiquated iPhone. This review has convinced me to get the HTC One instead of waiting forever for the iPhone 6, which I seriously doubt will be better than or as innovate as the HTC One anyway. And I must express my gratitude for the most thorough and thoughtful phone review that I have ever read to date. Reply

    You are wrong about card speed. Ask Brian. Reply

    If you have to remove the cover in order to access the MicroSD card then they have designed it somewhat poorly, that is not the case with all microSD equipped phones.

    That being said, It is unlikely that one will be constantly removing and switching microSD cards, hence the inconvenience of removing the back cover once every few weeks for whatever reason may be justifiable.

    The higher capacity versions of these phones come at a SIGNIFICANT premium, you may not feel like it is an issue to you but for others it may be when compared to the cost of acquiring a similarly sized microSD card.

    USB OTG cables are fine .... when copying files, but not when you wish to have the expandable storage with you at all times e.g music playlist? It would just make holding and carrying the device awkward and increase the chances of doing damage to the device when compared to microSD card.

    The developer edition costs $649 and is 64GB, game set and match. That's my next phone. Reply
  • darwinosx - Sunday, April 07, 2013 - link

    Yeah thats a deal. Any word on when they are selling these? i assume developer edition means you don't have to root it.. Reply

    The carriers know that very, very few people ue SD card slots. Google doesn't like them either and never has. Reply

    It has nothing to do with Google or manufacturers not liking them. It is application developers that don't like them. Apps being stored on SD cards means easier piracy. That is why Apple has never allowed removable storage. And application developers love them for it. Google and Microsoft are moving more this direction to appease developers. Reply
