The most interesting comparison here is for the older S4 devices against the newer but mid-range Snapdraon 400 devices, the Lumia 830 (and 735).The Lumia 920/925 and the 1020 should be almost identical, but there's a significant difference in favour of the older devices, perhaps because of the slightly non-standard configuration for the graphics chipset on the 1020? Or could it be that the extra Gigabyte of RAM is being used, but with a slight performance penalty while all the bits are shuffled around? The difference isn't huge, but I thought it worth noting.Interesting results then, with a few baseline conclusions. With the Sunspider javascript benchmark, included here as an extra (more processor-centric) data point, less is better (representing time in milliseconds to complete the requested operations). With the GFXBench stats, more is better, if you see what I mean, e.g. The restriction to only working on devices with 1GB or more of RAM (and preferably 2GB) is a bit of a pain, but there's still plenty of data that's worth highlighting.Īs usual with tables on AAWP and issues viewing them on Windows Phones because of the 'responsive design' and quirks in IE, the table is also available here as an image, gfxtable.jpg. Regardless, I thought the utility might be very interesting to use to answer questions about the relative performance of the various recent generations of Windows Phone. So there's a heavy focus on graphics speed, though of course processor speed and RAM also come into the equation here. ![]() they're mostly quite pretty to watch and give a good indication of device speed for games, for example. ![]() Two of the graphics demos, screenshotted. (right) There's a hefty 50MB download of resource and data files - this seems to be mandatory as you can't continue without this 'sync'. The main UI, in which you can run any or all of the graphics tests, plus compare scores for any test to those from hundreds of other devices. GFXBench DirectX is a suite of high-level and low-level 3D graphics test that measures the performance of DirectX 11 (feature level 9 and 10) implementations on various Windows devices (Windows Phone 8.0/8.1, Windows RT, Windows 8.1). Using console-quality 3D content, GFXBench provides tools for cross-platform 3D graphics benchmarking on all major desktop and mobile platforms (Windows Phone, Windows, iOS, OS X, Android). GFXBench is a free, cross-platform and cross-API 3D graphics benchmark that measures graphics performance, long-term performance stability, render quality and power consumption with a single, easy-to-use application. Ah well - there's little point in benchmarking at this low end anyway - there, it's all about price point. I did try GFXBench on lower-specced devices like the 512MB RAM Lumia 530 but it wouldn't run beyond its first warning message about resources needed. ![]() In the mix here were the Nokia Lumia 830, 930, 1020 and 920, the first two representing the newest x00 series of processors and the latter two the older S4 units.
