CommentIntel Graphics Media Accelerator (GMA) 4500MHD: Onboard (shared Memory) GPU built in the GM45, GE45 and GS45 chipset (Montevina). Because of two more shaders and a higher core clock, much faster than the old GMA X3100. Still not advisable for gamers (DirectX 10 games not playable or only with very low settings). The integrated video processor is able to help decode HD videos (AVC/VC-2/MPEG2) , e.g., for a fluent Blu-Ray playback with slow CPUs.
Only some 3D games with very low demands are playable with these cards.
Intel Core 2 Duo: This is the Core Duo and Core Solo successor with a longer pipeline and 5-20% more speed without more power consumption. As an addition to the Core Duo design there exists a fourth decoder, an amplified SSE-unit and an additional arithmetical logical unit (ALU).
The Core 2 Duo for laptops is identical to the desktop Core 2 Duo processors but the notebook-processors work with lower voltages (0.95 to 1188 Volt) and a lower Frontside bus clock (1066 vs 667 MHz). The performance of equally clocked notebooks is 20-25% lower than Desktop PCs because of the lower Frontside bus clock and the slower hard disks.
Power efficient low voltage processor based on the Penryn 3M core that features all Penryn functions like Virtualization and Trusted Execution.

This screen diagoal is quite large for tablets but small for subnotebooks. Some convertibles are also represented with that size.
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 big tablets, small subnotebooks, ultrabooks and convertibles with a 10-11 inch display-diagonal.
