Intel Graphics Media Accelerator (GMA) 4500M: The graphics core of the Intel GL40 and GS40 chipset features a slower clocked GMA 4500MHD (400 versus 533 MHz). Because of the slower core speed, full Blu-Ray Logo support is not given and the gaming performance is a bit worse.

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.

T6570: Entry level Penryn based dual-core CPU with a small 2MB level 2 cache and FSB800. Similar to the T6500 but featuring VT-x functions.» Further information can be found in our Comparison of Mobile Processsors.

14.0": 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.

2.2 kg: These sub-notebooks weight less than the average of all notebooks, but represent a heavier class of weight among the sub-notebooks. 13 inch displays are normal for this class of weight.
