Comment

Intel 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.


T9400:

The T9400 is a fast middle class dual core CPU for laptops and basically a Core 2 Duo P9500 with a higher TDP of 35 Watt.

14.1": 14 inch display size is a mixture between the small formats of subnotebooks and the 15 inch standard display. The reason why so many people like displays with medium size is, that this size is not exhausting for the eyes, does not need too much energy and the laptops can be kept quite compact.» To find out how fine a display is, see our DPI List.


2.4 kg: This notebook is lighter than the average of all notebooks. It is too heavy for sub-notebooks. 14 inch displays are normal for this class of weight.
