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.

    A better battery and camera in this would persuade me to upgrade in a heartbeat. I only hope that if they eventually replace the 5 with an equivalently-sized phone (5 2015?) they keep the wonderful screen. Reply

    Yes, I'm hoping for a Nexus 5 refresh with all the new fluff like the chip/ram/camera and battery. I think the Nexus 5 design and screen are perfect. My wife has a Nexus 5 and I'm still on my Gnex. Was hoping to get the 6 but with the size and price I'm going to wait some more. Roll on the Enyxos 810 phones and I might get whatever runs pure Android.

    PS. I cannot stand Touchwiz/Sense and whatever LG and Sony are doing on their "flagships." Thankfully Motorola has mostly stock interface.

    LOL! Good luck with that. The Nexus 5 is known to have weak radio signals and overall poor cell and WIFI reception. Not exactly the best choice and it's not really competitive with recent devices. Reply

    Because Google isn't a charity? Reply

    Google would have been better off making another "almost-flagship" at the $350 price point. I've been using Nexus devices since the Nexus S, but now... no, it's just too damn big and too damn expensive. Reply

    Having a Nexus 5, I see very few reasons to upgrade to this, unless you stronly like phablets. But in almost every area (battery life, camera, cpu performance, software..) it is almost a draw. Reply

    I'm curious, you've listed the nexus 5 as running lollipop in the first comparison chart... is it running the dev preview or the official release (that's MIA to the public)? Also, are the rest of the charts where the nexus 5 is listed results from the original kitkat release or from a lollipop build? I'm asking because the camera experience was greatly improved with the dev preview for the 5.

    Also I was worried about the display with moto making the 6... looks like that was justified. The 6 needs a price drop to sell IMO. As you state, the Note 4 is so much better on battery life and display and can be had for only $100 more (if you have T-Mobile anyway).

    I'm just saying it's confusing to show the 5 as having Lollipop but show the original test results from 4.4. Reply

    AT are comparing apples to oranges in charts and then writing words about pumpkins. i think the methodology error is that you (you as in AT staff) combined a performance review of a new os and a performance review of a new piece of hardware one too many times when it comes to phones. it worked for a while but this release its clear as mud... the outcome is that this review basically sitting in a vacuum- nothing to compare to objectively, so now your subjective comments are worth more than the benchmarks, which at this point are arbitrary. it's like benchmarking a new motherboard and using a just-released retail windows 8.1 on the tests of that new board, while the other motherboards in the benchmark charts are run on an windows 7 or windows 8. except there is no label in the charts to indicate which device is running what os. i bet if you did this with pc benchmarks people would flame you to death.

    while i understand your position with a new device and os combination making things more difficult to test, you make things more confusing by labeling the spec table for nexus5 as having os lolipop...yet the bench charts you show are for nexus 5 running the original release of kitkat.

    imho to address this issue in this specific review you should run additional benches for nexus 5 on lollipop (google released the production images on their dev site today) and add them to this review's charts. that way, the label in the spec table correlates to what i see in the charts. and that way, we have at least 2 lolipop devices to visually compare to each other in terms of performance. add the moto G and X performance numbers running lolipop for extra brownie points.

    i am not trying to attack the writer/editor, i love this site, just asking for additional data so i can see an apples to apples performance comparison of the new device to an older device running same os release. maybe i am just too traditional....

    I put Lollipop because Google will be rolling it out soon, but the results from all the tests are the original N5 results in Bench. I had been using the Lollipop preview on the N5 for an upcoming Android L review, which is how I determined that the N6 has regressions in UI performance. However, I disagree with the idea that there are any improvements to the camera on the N5 going from 4.4 to 5.0. I didn't notice any, and the software isn't going to save the camera system from just being inherently not very good. Reply
