CommentIntel Graphics Media Accelerator (GMA) 500: Integrated (onboard) graphics chip on the UL11L, US15L, and US15W chipsets with a licensed PowerVR SGX core. DirectX 10.1 support but because of low clock rates (100-200 MHz UL11L - US15) and only 4 shaders not suited for 3D games. The integrated video decoder accelerates the playback of HD videos (MPEG2, VC-1, AVC).
These graphics cards are not suited for Windows 3D games. Office and Internet surfing however is possible.
Intel Atom: The Intel Atom series is a 64-Bit (not every model supports 64bit) microprocessor for cheap and small notebooks (so called netbooks), MIDs, or UMPCs. The speciality of the new architecture is the "in order" execution (instead of the usual and faster "out of order" execution). Therefore, the transistor count of the Atom series is much lower and, thus, cheaper to produce. Furthermore, the power consumption is very low. The performance per Megahertz is therfore worse than the old Pentium 3M (1,2 GHz on par with a 1.6 GHz Atom).
Power efficient single core CPU with a very low performance. Offers more features (power saving, VT-x) than the N series Atoms.

This display size is a threshold between tablets and smartphones. Most tablets have larger screen diagonals but a lot of smartphones offer such a big screen.
Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.» To find out how fine a display is, see our DPI List.
This weight is typical for small tablets.
