CPU Performance

Much like other recent Android flagship devices, the Nexus 6 uses Qualcomm's Snapdragon 805 APQ8084. It's built on TSMC's 28nm HPm process, and it will be Qualcomm's final chip based on their Krait architecture. Although the use of a Krait CPU unfortunately means we don't get to take advantage of the 64-bit support built into Android Lollipop, it's still one of the fastest chips you'll find in an Android device today and will remain so until the first half of 2015. In order to measure CPU performance with some degree of comparability between different platforms, we turn to our typical suite of browser benchmarks, along with BaseMark OS II. 

SunSpider 1.0.2 Benchmark  (Chrome/Safari/IE)

Kraken 1.1 (Chrome/Safari/IE)

Google Octane v2  (Chrome/Safari/IE)

WebXPRT (Chrome/Safari/IE)

BaseMark OS II - Overall

BaseMark OS II - System

BaseMark OS II - Web

BaseMark OS II - Graphics

BaseMark OS II - Memory

As you can see, the Nexus 6 performs how you would expect a Snapdragon 805 device to perform. All of its scores are similar to the Galaxy Note 4 and Galaxy S5 LTE-A, with the exception of the extremely high BaseMark OS II Graphics score which I believe is some sort of error relating to the compatibility of the benchmark with Android Lollipop.

    Google really screwed up this years nexus devices.
    They are what I always buy, so now I'm left in a bit of a lurch.
    Probably will wait for the 64bit transition next (snapdragon 810, or exynos 7, though I'd prefer to avoid img gpus).

    I'm a little taken back by the poor battery life compared to the note 4. The screen is a little larger but damn.

    Hey, can we please get a storage benchmark on this? Ars claims it has big problems, is that a memory supplier issue? Thank you!

    Apparently there is a huge performance hit when switching on encryption on the Nexus 5 http://www.reddit.com/r/nexus6/comments/2m4jra/une...

    Can only hope this is a bug as this will pretty dramatically affect how the device performs.

    系统还是原来是原生系统 可终端设备已经不是原来的nexus的味道了

    So for twice the money (or so) of the nexus 5 we get a phone that loses many benchmarks (battery life, cpu, brightness, saturation) to the nexus 5. What's worse is that the nexus 5 was already trailing in battery life to begin with.

    Here's hoping google adopts some of the better phones into the GPE program.

    What seems to be most strange is the really poor battery life. Note 4 has just a bit smaller screen (10% difference only) yet more than 50% longer life. The cause isn't obvious, they both have AMOLED screens of same resolution, exactly same battery capacity and similar performance. The only differences are SoC (I get that it's the most important thing, but modern SoCs aren't that different in efficiency IIRC) and perhaps screen quality. When Galaxy Nexus came out, it had screen ahead of everyone else - but it was immature and extremely power hungry, paired with an already outdated SoC which GPU was overloaded with screen's resolution it had really poor battery life in browsing. Displays advanced and soon even screens with much smaller pitch were more efficient, processes shrank and GPUs consumed modest power on higher resolutions.

    Here, however, everything is nearly identical to Note 4. What is the cause of such a difference? Is the screen on N6 really is such a power hog (who's the supplier, anyway? Samsung, I suppose?). Though even the screen itself shouldn't be so problematic. Is the Exynos, and Mali in particular so much more efficient? Unlikely. I do think that this is caused by software, as seemingly it was with most Nexus phones - they were never really good at battery life. Even the Lollipop doesn't seem to help that.

    Yeah,on top of all that, Lollipop is said to make HUGE power efficiency gains over KitKat.
    So this story is a major upset to some MYTHS.
    What happened with pure, clean Android (supposedly more efficient), and the bloated, messy Samsung ROM (supposedly less efficient)?
    If the myths are true, Note 4 with Lollipop should have ridiculously better efficiency than this, on basically equal hardware.
  • darkich - Thursday, November 13, 2014 - link

    Oh and btw, the Samsung Note 4 ROM is vastly better than this.
    Besides offering the richest possible multitasking options, and all the S Pen extras, it actually makes one handed use easily possible.
    This aspect keeps on getting ignored in the reviews just because reviewers arent even thinking about using it.

    I ignored the one handed option too for months on my Note 3, but slowly it sank in, and now I see it as an essential piece of any proper phablet software.

    I've re-read battery and display parts of Nexus 6 and Note 4 reviews and now I think I do get it. Looks like Nexus 6 indeed has a problematic screen, like the Galaxy Nexus had before - it has way too high power consumption and low max brightness. However, that by itself shouldn't cause too much of a problem in real use (unless you are typically browsing in direct sunlight).

    Battery life test is done at 200 nits, almost the max of 250 nits for Nexus 6. GNex at that brightness level had some serious power consumption from display alone, well over 1 watt, so screen's power consumption dominates the test done like that. IRL, you don't just load the page over and over, with modest CPU and GPU load, you actually scroll a lot, seriously loading GPU - you actually scroll way more than you do anything else, so RL web browsing life is dominated by GPU power consumption, as the screen is usually running at low brightness level and it's contribution to power consumption isn't that big.

    So, I suppose, while for sure Nexus 6 will have less battery life than Note 4 due to crappy screen tech, in real life, there shouldn't be too much of a difference, probably around 10%, 15% at most.
