GPU Performance

By Anand Shimpi

Although there’s a CPU core count difference between the MSM8960Pro and the APQ8064 Snapdragon 600 platforms we’ve tested, on the GPU front both use the same IP block: Adreno 320.

The max GPU frequency on the Moto X is 400MHz, compared to 450MHz for the APQ8064 Snapdragon 600 based Galaxy S 4. The difference in GPU frequency is small, and Android games typically have a large CPU bound component so it isn’t totally unfeasible for the Moto X to be among the fastest Adreno 320 phones on the market.

Looking at 3DMark we see just that. The Moto X is the fastest Android phone we’ve tested here. The advantage has nothing to do with GPU frequency however, if we look at CPU frequency over time it’s clear what’s going on.

3DMark - Demo

3DMark - Graphics

3DMark - Graphics Test 1

3DMark - Graphics Test 2

3DMark - Physics

3DMark - Ice Storm

The graphs below show a full 3DMark Ice Storm run, including demo, graphics and physics tests (in that order):

The Moto X’s CPU cores are running at 1.7GHz for all of the 3D tests, and only drop down to lower frequencies during the physics test. The SGS4 by comparison has more cores, running at ~1GHz for most of the benchmark. Given the more CPU bound nature of 3DMark, the Moto X manages to pull ahead.

GFXBench 2.7

BaseMark X and GFXBench 2.7 on the other hand shift the workload to a more GPU bound workload, and we see the Moto X take a couple of steps back.

    Great review, Brian and Anand! :)

    Did you notice any transition animation jank/stutter and sluggish/choppy scrolling on Moto X day to day use? Would really like the smoothness of Apple iOS landed on Android world in the future. :)

    I often encounter transition animation jank/stutter when opening or closing apps, switching in between apps, and entering-swiping-leaving home screen on Nexus 4 running Android 4.3. Perhaps the soc and battery thermal throttle and lack of random write IO are the culprit of janking or stuttering on Nexus 4 transition animation and scrolling performance.

    Thanks AT for the review. I've not seen such an in-depth review that actually considers the hardware components of this phone so objectively without doing the "OMG-no-1080p-screen-no-quadcore" whining. :) Appreciate it.

    But where is the Lumia 925 and Lumia 1020 reviews? :( Please post them too, they came out way before the Moto X.

    I created an account just so that I could thank you for writing such a great review! There are so few true tech writers around that actually write about technology. I am glad there we still have anandtech to have reviewers that actually review with this level of technical detail and scientific backing to what is written. Thank You!

    I, your average user, am buying a Moto X, honestly. And here's why: I researched the HTC One and Mini, Samsung S4 and Mini, and the Moto X is the clear winner. Primarily, the One and S4 are too large for me, as I want something pocketable and easy to handle. In addition the S4 is too complicated with both"features" I would not use and Touch Wiz. I do love the One's front facing stereo speakers (let's make this standard in all phones) and the Zoe photo feature, but again, the Moto X is pocketable with the largest ratio of screen to phone dimensions of possibly any phone on the market, and 720p is just fine especially given it allows for long battery life. I drive alone in my car quite a bit and have yet to find a bluetooth headset that works well. I am really looking forward to using the voice activated controls of the Moto X to do all kinds of things, as well as enjoying the quality of the speaker to actually hear the person on the other end. Active notification is pretty great too. The phone does seem priced a bit high, but for a tool that I'll use everyday that will increase my productivity and make my life easier and safer while driving, an extra $50 or so is certainly worth it. Last, I expect this phone to get Android updates quickly, right after Nexus devices, and this will only enhance it's already awesome software abilities well into the future.

    PC Magazine reported that Iqbal Arshad, Motorola's senior vice president of engineering said "We've done additional optimizations on top of that such as optimizing the entire Linux user space to move it to an ARM instruction set, cache optimization, Dalvik just-in-time optimization, and we've changed the file system."

    In this review, you guys covered the changes to the file system, for which I applaud you for being much more thorough than any other reviewers, but can you comment about any of the other things he mentioned?

    Simply put, Brian, you've penned an outstanding review. Depth, tone, observation, telemetry to conclusion ~ all top shelf. It's a genuine critique. Thank you for the enormous amount of work and heart put into this piece. The passion and dedication shows, and it's a true pleasure to read.

    I've never understood why geeks worship at the altar of "stock Android." Believe it or not Google is not the only company that has interesting ideas on how to create a UI for a mobile phone or tablet. Handset makers can add useful enhancements.

    I've got a Nexus 7 and an HTC One and, before that, a Moto Droid Bionic. All worked fine and I wouldn't even pay $5 more to change the HTC One or the Droid Bionic to "stock Android".

    I'm excited to hear that audio testing will get more visibility. I also really appreciate the GIFs.
