Motorola Moto E (2nd Gen) Review

GPU And Gaming Performance

Mobile GPU performance is becoming increasingly important as people begin to see their phones and tablets as portable gaming machines. This section explores GPU performance with several synthetic and real-world game engine tests. To learn more about how these benchmarks work, what versions we use, or our testing methodology, please read our article about how we test mobile device GPU performance.

It is no surprise that the Moto E outperforms the Moto G in the CPU-bound Physics test by 16%, but it is surprising to see the Adreno 305 in the Moto G ahead of the newer Adreno 306 in the Moto E. While Qualcomm’s Adreno GPUs are something of a black box, based on the product numbering it is reasonable to suspect the 306 is just a slightly tweaked 305, with maybe a few performance optimizations. There is one big difference between two, one that can potentially explain intuitively reversed results: clock frequency. The Adreno 305 in the Moto G (2nd gen) runs at up to 450MHz, while the Adreno 306 in the Moto E (2nd Gen) runs at up to 400MHz. Not taking into account any architectural changes, or the fact that performance never scales perfectly with frequency, this is a 12.5% advantage for the Moto G.

The Moto E is definitely not a gaming powerhouse, trailing the Desire Eye by a factor of 5.5x overall. Compared to the Moto G, we see about a 12% deficit that’s consistent between Dunes and Hangar, equaling the GPU clock frequency spread between the two.

The Lumia 830 manages to squeeze past the Moto G in both graphics tests despite using the same Snapdragon 400 SoC. Since the benchmark uses Direct3D feature level 9_3 when running on Windows instead of OpenGL ES 2.0 for Android, the small difference could be due to the graphics API overhead.

In the onscreen tests, the Moto E pulls ahead because it renders at a lower 960x540 resolution versus the Moto G’s 1280x720.

The performance gap between the Adreno 306 and the Adreno 330 remains the same when moving to the high quality tests. However, we see the Moto E swap places with the Moto G. This is likely a combination of the Moto E’s higher memory bandwidth and better CPU performance.

The Lumia 830 could not run the high quality tests because of insufficient memory.

Both of the Moto devices choke on the pixel shader heavy GFXBench Manhattan test. They still fare better than the Lumia 830, which refused to run it at all.

Once again we see a 12% deficit between the Moto E and Moto G, although neither perform well.

In GFXBench 3.0 Alpha Blending, the Moto E (2nd gen) falls behind the Moto G by a wider 28% margin in this test of texturing capability. This test is usually memory bandwidth sensitive, so it is odd that the Snapdragon 410 does so poorly here. Granted, it is still 3x faster than the Lumia 830.

The ALU test stresses fragment shader computing. Here we see the familiar -12.5% delta between the Moto E and Moto G. Nearly the same delta shows up again in the Driver Overhead test.

By now it should be clear that neither the Adreno 305 or 306 are capable of playing the most demanding Android games. Fortunately, most mobile games are not nearly as demanding as the graphics benchmarks we use. The lower screen resolution of the Moto E (2nd gen) also helps it outperform the the Moto G in onscreen tests, and it is still capable of handling some casual gaming.

The Moto G (2nd gen) maintains about a 12.5% advantage over the Moto E (2nd gen) in graphics performance at the same resolution, the exact same difference in GPU clock frequency between the two. It’s unfortunate that the Adreno 306 in Snapdragon 410 is slower than the Adreno 305 in the older Snapdragon 400 head-to-head. I suspect the lower GPU clock for the 306 is a result of squeezing the A53 CPU cores, which have a lower performance per watt than the A7 cores, into the same power envelope.

    Lenovo k30-W for the win
    all the above +
    HD ready resolution 720p
    internal storage 16GB
    the only con, is there OS, which is good, but not really vanilla android

    i bought one and had to return it, it restarts while charging and motorola at this moment hasn't solved the problem, a shame because it is a nice fast phone
  • tekelymailcom
    The only international variant mentioned is the XT1505 but there are more. I found very interesting the XT1523 which has 16GB, dual sim and digital TV reciever.

    There might be an error in the speaker/sound part above. "Plugging in a set of good headphones provides a similar listening experience. Relative to the iPhone 6, bass has less punch and the Moto E lacks clarity; the signal-to-noise ratio seems higher." The S/N ratio on the Moto E should be LOWER, not higher if it sounds like its lacking clarity.

    Good point. I must have been thinking of THD, which is expressed as a percent. I've made the necessary correction.

    I also purchased this phone and experience the restart while charging issue. Also, the performance is on par with a very, very basic Lumia 510 I had the misfortunate of having to use for a short time. The phone chugs while multi-tasking. And I mean by just hitting the home screen instead of closing out of apps. And even that takes an inordinate amount of time. I'm talking a noticeable 3-4 seconds after you hit home: your background wallpaper shows up, but no icons or app try icon, then another second or 2 later the icons show up. It's performance is dreadful. As well is its 1GB of memory. If I'm in the car I use bluetooth and Google Play Music / Google Maps. If I begin navigating to a destination and begin playing music Maps will close. I'm assuming due to lack of sufficient RAM. If I'm at a stop light and open snapchat, Google Play Music, Maps or Waze will close if I view a Snap. It's really rather frustrating the more you use the device. And I don't have many apps on here at all. Essentially just FB, Twitter, Snapchat, Waze, WatchESPN, HBOGo. That's all. It's frustrating seeing reviews like these on this phone that don't actually put it through its paces for a decent amount of time.

    I'm sorry you had a poor experience, but thanks for taking the time to add your story. This is why we included the HTC Desire Eye in our performance evaluation, so our readers could see the performance delta between some lower-cost devices and last year's flagships running Snapdragon 801 SoCs, which are now considered mid-tier.

    Our unit did not experience the restart while charging issue, and while this comes as no solace to you, the Moto E handled its 1GB of RAM better than the Lumia 830 did during our testing and evaluation.

    I've experianced BT connectivity problems with both the Moto G and this new Moto E when connected to various cars. I'd be wary purchasing these phones if you rely on BT connectivity in your cars.

    Interesting reading and thanks for the review.

    I bought the original Motorola-E (3G) for an older family member as a replacement for their aging Nokia clamshell phone that barely managed a days life depite having a new battery. The problem was not only living in a relatively weak signal area but more that it was constantly running Bluetooth whilst being paired with a car-stereo for hands-free operation. Therefore I assumed that a more modern cellphone with a newer Bluetooth implementation could last a whole lot longer.

    After extensive internet research I dicovered that the original Motorola-E had very good battery life (a few day of talk time) and very good call-quality, and seeing as said family member was likely to be using it mainly for calls I could assume that the internet-reviewed (hammered!) battery-life could thus be extended, and indeed this was proven correct.

    At that time and around 90-100 GBP from the local Argos & SIM free I considered it a cheaper alternative for a mainly calls, minimum data use (unless at home on the WiFi of course - I'm thinking of updates), small-ish, slightly rugged; Gorilla-Glass, removable back-cover and serviceable (replacement batteries). A throw in the bag type mobile that might survive a re-shuffle with other items in said bag (keys, pens, loose-change, etc.). It also uses a (charger not supplied) standard micro-USB connector for charging, so the car-charger and home-charger can be any number of generic cheap types. Thieving was another consideration, hence a cheaper-end phone hopefully providing a less attractive target.

    A chubby-stylus was added for less that a pound, the type that can be attached with a small line to the headphone socket for safe keeping, as older family members tend to have drier skin and so touch screens aren't always as accessible to them.

    The only thing missing iirc was the camera light that can be a handy aid on dark nights, however to mitigate that the main-screen illumination can also be sufficient for emergency use.

    I have to say that I am still pleased with the original Motorola-E purchase and have to wonder how the battery life compares with light useage when the newer model likely required a larger battery due to the faster processing power and extra electronics that it now facilitates, some can be switched off I know but always leaking power.

    I have an issue with the Battery Life tests you've done. The new 2015 Moto G uses the same 2390mAh as the new Moto E, and not the 2070 mAh. The 2070 mAh is used in the old Moto G versions. So, while the 4.5in screen of the Moto E would increase battery lifetime over the 5.0in Moto G, the difference should not be that big.

    The Moto G (2nd gen) has a 2070 mAh battery according to Motorola, and this is the model we tested. I should have used the generation nomenclature (like in the text) in the chart rather than the year to avoid confusion.

    There are currently 4 versions of the Moto G:

    The original, released in Nov 2013, which had 4.5in screen, 5 mpx cam, and 2070 mAh
    The updated one, released in May 2014, same specs except had storage expansion and LTE, same 2070 mAh.
    The first 2nd gen, released in Sep 2014, which had 5in screen, 8 mpx cam, no LTE, same 2070 mAh.
    The updated 2nd gen, released in Feb 2015, same as above, except has LTE and 2390 mAh. This is the one you should have been reviewing, but i guess you mixed them up. Dont believe me, here's the comparison of the last 3 versions (the original excluded cause the site can only compare 3 at a time)
    http://www.phonearena.com/phones/compare/Motorola-Moto-G-LTE,Motorola-Moto-G-2014,Motorola-Moto-G-LTE-2015/phones/8655,8898,9155

    And before you say that site has it wrong, ALL proper reviews comfirm it has 2390 mAh battery, and decent battery life span in tests backs this up. And I even checked at my usual online shop and confirmed it as well.

    While a 4G version of the Moto G (2nd gen) with a larger 2390 mAh battery does exist, my understanding is that it was only ever released in Europe. There is no mention of it on Motorola's US website, and when I requested a Moto G review unit from Motorola, they sent me the 3G (2nd gen).

    Have you actually seen one for sale in North America? Can you buy one unlocked? I checked online and could only find the 4G (1st gen) for sale.

    Well, that is the oddest thing I have ever seen. Why wouldn't Motorola sell the best version of their merchandise in the US of all places? That's just bad business in my opinion. Well, at least the confusion is cleared up, but the review is misleading to anyone in Europe.

    It's definitely confusing, but not as bad as the Galaxy Note 4, for example. It comes in over 20 different SKUs for different regions and carriers, and they have different combinations of SoCs, baseband processors, audio codecs, camera sensors, etc.!

    While we have readers from all over the world, the main Tom's site focuses on North America. We do have regional Tom's sites (UK, Germany, France, Italy, etc.) that cover products sold in those areas, though.
