Performance: Web-based Testing
Test Methodology: Unfortunately, this page may be a bit dry and tasteless for you, if you're used to digesting page upon page of performance benchmarks. The fact of the matter is, there really aren't currently that many ways of benchmarking performance on a Windows RT device currently, other than a couple of web browser-based metrics. Only Microsoft can run Windows 32 apps on Windows RT currently, like MS Office 13 for example.
And of course Android and iOS-based benchmarks are a no-go as well. With that in mind, we can still run a couple of basic tests, like SunSpider and Rightware BrowserMark.
In SunSpider, the Windows RT-driven ASUS Vivo Tab RT takes the performance slot versus all other major tablet platforms currently, including iOS and Android. Even the powerful quad-core Samsung Exynos SoC in the Galaxy Note 10.1 doesn't quite keep up with Android Ice Cream Sandwich on board. We should note, although not quite Apples-to-Apples (no pun intended), the iPhone 5's A6 SoC and iOS 6 do outpace Windows RT, NVIDIA's Tegra 3 and the Vivo Tab RT here by just a hair at 941.8
Unfortunately our benchmark testing with Windows RT right now is a bit on the inconclusive side but we'll return to this in the weeks and months ahead, as new tools and measurements become available to us.
