The little brother of the flagship Nokia Lumia 920, the 820 has nothing to be ashamed of when it comes to performance. Actually, the 820 has the same dual-core Snapdragon S4 processor as the 920, running at the same 1.5GHz speed. From a developer’s perspective, the big difference is the screen – while the 920 has 1280x768 pixels, the 820 keeps the modest 800x480 pixel resolution of Windows Phone 7. Most of the differences between the 920 and the 820 have to do with how the 920 has to work with 2.5 as much pixels as the 820. It is worth noting that the 820 only has minimum requirement for 800x480 Windows Phone devices is 512MByte RAM, while the 920 has twice as much. This also boils down to the difference in screen pixels – apps on the the 920 need more RAM simply to decode the high resolution bitmaps and keep them in memory.
