ATI Mobility Radeon HD 3470: Faster clocked HD 3450 and successor of the HD 2400 XT but with DirectX 10.1 and due to the new 55nm process, higher clockspeeds. Avivo HD video functions allow the decoding of HD videos.
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.
P8600:
Fast but still not overpriced dual core CPU. For most games and multimedia applications sufficient and due to the 25W TDP even for smaller notebooks useable.

There are hardly any tablets in this display size range anymore. For subnotebooks, on the other hand, it is the standard format.
The advantage of subnotebooks is that the entire laptop can be small and therefore easily portable. The smaller display also has the advantage of requiring less power, which further improves battery life and thus mobility. The disadvantage is that reading texts is more strenuous on the eyes. High resolutions are more likely to be found in standard laptops.
