Even though the hardware specs of all the Windows Phone devices are almost same, there are some differences when it comes to performance.
As you can see in the video above, Nokia Lumia 800 which has faster processor and graphics engine performs better than Samsung Omnia Windows Phone. The visuals are better with more FPS and even performance in some games.
Still both the devices are running a single core processor; Â imagine what Windows Phone team will deliver on dual core processor devices?? We have to wait at least another 3 months too see that in action Â !
