Intel Graphics Media Accelerator (GMA) 950: Intel Graphics Media Accelerator 950 is an integrated (onboard) graphic chip on Mobile Intel 945GM chipset. It is a faster clocked version of the GMA 900 and supports no hardware T&L (Transform & Lightning) accelleration (which is required for some games).

Only older games can be played fluently with these graphics chips (if they were not too demanding). Shared memory graphic cores in this category got the advantage of less heat production and longer battery runtimes. For office, internet, image processing, and video editing tasks these graphics chips are still useable without any restrictions.

Intel Core Duo: Double Core processor with a very good relation of performance to current consumption. The 2 MB L2 Cache are used together by the double. The maximum capacity of 31 watts is only 4 watts more than with the Pentium M (predecessor). Both cores are lowered automatically and independently of each other by speed steps down to 1 GHz. In addition it now supports also SSE3 instructions. At least it is just as fast as a equivalent Pentium M. With applications, which were designed for multi-processors, the performance can be nearly twice as fast as with the Pentium M (e.g. CineBench around 86% fast)

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 current and the laptops can be kept quite compact.
