In addition to using the Lumia 925 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 system-level benchmarking application available within the Windows Phone Marketplace. To date, it's one of the only effective ways to test the small-but-growing stable of WP handsets. We've compared CPU, Data and GPU benchmarks below with the Dell Venue Pro, Samsung Focus, Lumia 900, and Lumia 920.
Performance-wise, the Lumia 925 sits right about where the Lumia 1020 and 920 found themselves. The harsh reality is that Windows Phone hardware, at least internally, has evolved very slowly. We're seeing new phones, but the same 'ole numbers.
