System Performance

While subjective judgments of performance may be possible to make when the delta is significant, when the gap gets increasingly close within the range of perceivable performance differences it becomes important to rely on more precise and accurate methods of measuring the overall performance of the mobile device. For the most part, when we’re discussing system performance the single biggest factor is often the SoC, which makes sense given that an SoC contains the CPU, GPU, video encode and decode blocks, memory bus, and DSPs. There are other aspects of the device that determine the overall perception of performance and things that can have a meaningful effect on performance, but the SoC is often the gating factor.

In order to test this we run mobile devices through our standard suite of benchmarks. In the case of the Galaxy Note5 and Galaxy S6 edge+, there shouldn’t be too many surprises given the commonality in components with the Galaxy S6.

If you guessed that performance in these benchmarks would be similar to the Galaxy S6, you'd be right. Given the shared SoC and general commonality in components performance remains as high as it is with the Galaxy S6. In some cases we see improvements, likely a combination of changes to Chrome and changes to areas like the frequency governor to respond faster to changes in load. It's probably fair to say that the Exynos 7420 will continue to be the best SoC for Android mobile devices in 2015, although it's likely that we'll see significantly increased competition for 2016.

    People don't buy the iPhone because of that.
    You must be one your self to call people who by them a sheep.

    Why you haven't add the iPhone 6s results? Are you still updating the bench?
  • Ryan Smith - Friday, October 2, 2015 - link

    The iPhone 6s is still being reviewed. This was actually completed ahead of the 6s launch, though we had to hold off on publishing it for a few days.
  • lucam - Friday, October 2, 2015 - link

    Fair enough, thanks.

    Is there any timeline for when the 6s/6s+ review will be completed and published? Next week perhaps?
  • Kuzi - Friday, October 2, 2015 - link

    Their Apple overlords ordered iAnandtech to hold off publishing the Note 5/Edge 6 + review until iPhone6S/6S+ are released as to not jeopardize their sales.

    If that were true then their Apple overlords would also have ordered them to include the iPhone 6s benchmark results to show the Exynos 7420 being crushed by the A9. Since that didn't happen, your assertion is wrong.
  • Kuzi - Friday, October 2, 2015 - link

    They did just that few days ago by showing preliminary iPhone 6S benchmarks.

    A9 GPU is much faster yes, but CPU is faster only on single/dual apps/benchmarks. Android utilizes quad-cores when running apps as shown on Anandtech last month, so CPU performance for exynos 7420 or Snapdragon 810 should be able to match or beat that of the A9.

    Android uses 8 cores well - that article also showed apps themselves don't. Games and such which need the performance most, usually don't use more than 3-4, even if Android is good at using 8.

    because most arm soc's never use 8 cores all at once.. it's big.Little.. 4 core for high performance, then 4 core for mundane task
