ATI Mobility Radeon HD 530v: Renamed HD 4350 graphics card and therefore an entry level GPU with DirectX 10.1 support.

Only some 3D games with very low demands are playable with these cards.

» Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.


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.


T6670: Entry level Core 2 Duo based on the Penryn core. Similar to the C2D T6600 but with VT-x Virtualization and higher temperature specification.» Further information can be found in our Comparison of Mobile Processsors.


15.6": 15 inch display-variants are the standard and are used for more than the half of all notebooks. 15.4 inch display with 16:10 are the standard for notebook displays. However nowadays, more and more 16:9 displays with 15.6 inch appear. 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.


2.6 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.
