Performance

The Microsoft Lumia 640 features hardware we've seen earlier in a wide variety of entry-level and older mid-range handsets. Oddly, rather than opting for newer Snapdragon 410 silicon, Microsoft has used Qualcomm's older Snapdragon 400 MSM8926 SoC, which comes with iv ARM Cortex-A7 CPU cores clocked at upwards to 1.two GHz, and an Adreno 305 GPU.

For a device released in 2022, it's disappointing to see the inclusion of an SoC that first hit the market in 2022. The Snapdragon 410 is a handy upgrade on the Snapdragon 400, providing a performance heave of effectually 20% in CPU-limited tasks, while besides supporting 64-scrap code. I suspect Microsoft has stuck with the Snapdragon 400 due to their familiarity with it, but it actually is time to move on.

The Lumia 640 also comes with ane GB of RAM, which is at present standard for entry-level handsets, and 8 GB of internal NAND that can exist expanded upon via the microSD card slot. 8 GB is a pretty small corporeality of storage to include out of the box, and so it'll definitely be worth picking up a microSD card and then you can actually install a decent amount of applications. Hopefully we're not also far away from having sixteen GB of storage as standard in entry-level devices.

Earlier I get into the criterion results for the Lumia 640, it's worth talking about the full general functioning of the handset in everyday usage. One thing I've noticed with Windows Phones recently is that unless yous have a flagship device like the Lumia 930, the OS tin can feel slow and sluggish at times. The long animations between screens, and somewhat frequent occurrence of the 'sliding dots' loading indicator (or the even more annoying full folio loading screen), makes the Lumia 640 feel pedestrian to use.

The slowness of the Lumia 640 is peculiarly noticeable up against electric current Android devices, running Android 5.0 Lollipop, that characteristic similar Snapdragon 400 hardware. While both devices return their animations impressively smoothly, electric current versions of Android just open up apps, switch betwixt them, and perform tasks more than quickly than Windows Telephone. Hopefully this is something Microsoft is working on in Windows 10 Mobile.

Moving on to benchmarking the Lumia 640 it should exist noted that a lot of benchmarking applications are quite buggy on Windows Phone compared to their equivalents on Android. Basemark X, for example, simply refused to run on the Lumia 640, while several other tools crashed multiple times. I guess this is indicative of the country of applications on Windows Telephone right now.

Equally you can see, the Lumia 640 performs about where you'd wait for a Snapdragon 400-powered entry-level device: towards the bottom of most of our charts. Spider web performance is disappointing for this device, though Internet Explorer has historically struggled on Windows Phone compared to Safari/Chrome on iOS/Android. Graphics performance is adequate for 720p, though inappreciably outstanding considering the ii-year-old GPU.
