CPU Performance

Performance is where the “flagship” name falls apart. The internals of the Lumia 830 are essentially identical to that of the Lumia 635, and that model is cheaper. The Lumia 830 does have 1 GB of RAM, and 16 GB of onboard storage, but the MSM8926 cannot be the SoC in any device labeled as a flagship.

The Lumia 930 with the 2.2 GHz quad-core Krait CPU is very fast, and changes the way you expect Windows Phone to operate. Microsoft has done a great job with the UI and animations of Windows Phone to make them fast and without the jitter of some platforms, even on low end hardware. But that does not help in-app performance, nor the app loading times. The Lumia 930 was a breath of fresh air in regards to performance of a Windows Phone, and unfortunately the Lumia 830 lags behind.

To test CPU performance, we use some standard web based benchmarks as well as BaseMark OSII from Rightware. This gives us a comparison across operating systems. For the graphs, I have tried to get a representation of devices that might be shopped against the Lumia 830 in order to keep the graphs reasonable and meaningful, but if you are curious to see how it compares against any other device we have tested, please check out our benchmark comparison pages in Bench.

Performance is poor across the board. The Snapdragon 400 with quad-core Cortex A7 just cannot compete with many other phones in a similar price range.

Next up, we will take a look at the GPU performance. This is measured with Basemark X 1.1 and GFXBench numbers, and with a caveat – the current GFXBench version is 3.0, but only 2.7 is available on Windows Phone at the moment (3.0 is listed as coming soon) so we do not have as large of a list of comparable devices for the GPU results.

GPU Performance

The Lumia 630 with only 512 MB of RAM is unable to install GFXBench, but we can still compare the 830 to the 930, 1020, and a couple of other devices. The Adreno 305 GPU in the Snapdragon 400 can be compared to the Adreno 225 in the Lumia 1020, but regardless is quite a step down from the Snapdragon 800’s Adreno 330 GPU found in the Nexus 5 and Lumia 930. Apple has consistently pushed for a better GPU in their products and that shows again here even though these are not the current flagship models from Cupertino.

The biggest disappointment with the Lumia 830 is performance. The Lumia 1020 outperforms the 830 in Basemark X 1.1, but both devices fall well short of the Snapdragon 800 Nexus 5. With a device marketed as an “affordable flagship” it would have been nice to see a step up in performance here. The Snapdragon 600 for sure seems like it would have been a perfect fit to fill out the Lumia lineup.

    Moto G can barely fight with 630. Definetly not with 735 and 830.

    like others here I have a 2 year old Lumia 920 and am looking for an upgrade, but there are limited options available. When I was essentially running a business out of my cell phone I was looking to upgrade to the 1520 (or better yet the long rumored 1525 what seems to have gone up in smoke), but now that I am a student and have a laptop a normal sized phone sounds much more appealing.
    I was looking really hard at the Icon/930, but the lack of Glance and SD card support are in fact deal-breakers. I use glance all of the time on my 920 (especially now that weather shows up on Glance... best simple feature ever!), and if I had SD support then I could fit my whole music collection, as well as more pics and vids of the kiddos to show off to friends and family. Plus the fact that it is only available on VZW, and I am not going there and will stick with ATT/T-Mo for service.
    So then that leaves the 830. Playing with it in person, it is a great little device, and if you sell off the useless bundled fitbit for ~$80+ then the price is more than reasonable. It is a step down from the Lumia 920... but only a minor step down, and some things (like SD support, much lighter weight and slimmer design, significantly better camera, bigger display/less bezel, etc.).
    But at the end of the day it is not a flagship. The processor is slower than the 920 for most of my uses (may be different if you play more games), the screen quality/resolution is lower, the build quality is not as good... it is exactly as advertised: an "affordable flagship" with all of the features, but at lower spec. The other issue is that it is not going to get the 'next gen' features like "Hey Cortana", or the 3D touch tech that MS is working on.

    For myself at least, the only issue that my 920 has is that the GPS has lost it's mind and it refuses to narrow my position down closer than a 2 mile radius which makes navigation useless... but everything else on the device works fine and is in great shape. Unless there is some sort of crazy Black Friday deal, I think I am going to stick with the 920 until next summer when the next gen devices hit with Windows 10. It would be nice to have GPS again from time to time, but I would rather muddle through with GPS-less maps which still work and buy one high-end device later rather than a midrange device now and a high-end device in 6 months.

    Since Windows Phone like most Android devices normally gets updates from the carriers...which is to say, they don't get updates- I'm wondering if we should all be running Windows Phone in developer mode is it gets timely updates. I have my 928 set like that and it's gotten probably 4 updates since 8.1, BUT it hasn't gotten any updates to the Nokia specific software yet.

    Still...I assume that means I'm getting security issues fixed.

    (For that matter, I have no idea why my Nexus 7 tablet always takes months to get OS updates...)
  • synaesthetic - Tuesday, November 25, 2014 - link

    The reason your N7 takes so long to get updates is because that much time actually passes between Android version updates. Google has placed most of their functionality into Google Apps and the "Google Play Services" app, a move both intended to strengthen their ecosystem and fight device fragmentation.

    The OS itself only gets updated for major changes to low-level OS components, or when a new mainline version of Android is released.
  • Wolfpup - Wednesday, January 28, 2015 - link

    No, what I mean is that after an Android update is supposedly released, and other Nexus devices are getting updates, my Nexus 7 takes MONTHS to get them. It was supposedly updated in November, for example, and STILL hasn't been updated.

    I believe that your 2G/3G web browsing battery life is missing the iPhone 6. Since many people don't live in an area where LTE is constantly available, it is suspect to omit this information.

    My guess is that the battery life for an iPhone 6 2G / 3G browsing session is bad to very bad, and you have left them off the charts to obfuscate this.
  • Brett Howse - Tuesday, November 25, 2014 - link

    I didn't compare the iPhone 6 in any chart since it's not in the same price range. As for 2G/3G for the iPhone 6 in particular, I did not review that device but my suspicious is that it was due to the time crunch for that phone, since battery life testing takes the longest for any of our benchmarks.
  • Busterjonez - Tuesday, November 25, 2014 - link

    Fair point about the 6, I hadn't noticed it's absence on the other tests.

    Why include an iPhone 5s / 5c in the WiFi battery test, but not in the 2G / 3G battery test?
  • Brett Howse - Tuesday, November 25, 2014 - link

    The iPhones are not in bench for the 2G/3G battery life is the only reason they were not included. They were only tested as LTE:

    The iPhone 5 was the last one tested for 2G/3G and it isn't sold anymore so I did not include it in my charts.

    Looks like a good phone that is priced way above its price range. You can buy a HTC Desire 820 of expansys or Newegg now for around $360-380 about the same price you can find a Lumia 830.

    I would bet that the Nokia would have a better camera but if you're just looking at numbers the HTC has the 13mp rear camera vs the 10mp Nokia. Has a 8mp front camera vs the .9mp Nokia.

    Snapdragon 615 vs the Snapdragon 400. 2GB LPDDR3 vs the 1GB LPDDR2 Nokia. Depending on what floats your boat 5.5" display vs 5" Nokia. Both are 1280x720 16GB storage and microSD support. I think it would be hard on salesmen to pitch coupled with the poorly supported Windows Phone app store.
