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 pity plastic. Samsung of all companies can't spend the cash on something better built? As for the faster hardware, I have no doubt you wouldn't notice the difference in your usage. Reply

    Drop 'em both, see which breaks faster. Reply

    It appears plastic breaks faster.

    I'm torn. I've dropped my sgs3 several times on concrete and the wounds are barely noticeable. I suspect the One would not fare so well... Reply

    How is it inferior hardware? You may believe a removable battery means "better hardware" but putting a plastic door at the back of a phone is not an impressive feat (nor a relevant feature for the vast majority of users), Micro SD is another feature that requires no major effort to include an is not something the general public cares about.

    The screen, as usual, will be better in the One, the camera is better, the build quality is superior, the speakers are better, the screen size is more comfortable (and so is the shape of the phone), what exactly is better hardware-wise from Samsung?

    The Qualcomm SGS4s will have a higher-clocked CPU (1.9GHz compared to 1.7GHz on the One) and a higher-clocked GPU.

    And many people would much prefer an AMOLED screen to a LCD one.

    People may prefer AMOLED (I don't know exactly who except fanboys, regular customers I'm sure don't know what AMOLED is) but is objectively inferior.

    The CPU and the GPU will be clocked a tad faster, but I don't think that's "superior hardware" is the same processor, just clocked higher.

    But now we know the S 4 lags all over and has a little worse battery life than the one. Reply

    It's the same CPU just over-clocked faster. So in that respect, there is no difference in the CPU hardware... Reply
