In addition to using the Lumia 920 in a variety of everyday usage scenarios, we also conducted some formal performance testing to see how well the handset compares to other smartphones. WP Bench is a performance-oriented benchmarking application within the Windows Phone Marketplace. To date, it's one of the only effective ways to test the small-but-growing stable of WP7 handsets. We've compared CPU, Data and GPU benchmarks below with the Dell Venue Pro, Samsung Focus, Lumia 900 and HTC Arrive.

Performance-wise, we've never seen a Windows Phone tear up the benchmarks like the Lumia 920. When compared to single-core offerings that used Windows Phone 7 there's simply no comparison. The 1.5GHz Snapdragon is a good fit for the phone, and it helped to deliver WPBench scores that would have been completely impossible given the hardware limitations tied to the WP7 platform. Windows Phone as a mobile OS has always been silky smooth, even on last-gen hardware. But with a potent SoC , 1GB of RAM and a mobile OS that simply doesn't need a ton of resources, you'll be hard-pressed to overtax the Lumia 920. Everything from sifting through apps to playing a complex game seemed to be no trouble at all for the device.
