NVIDIA GeForce 8600M GS: NVIDIA GeForce 8600M GS is the DirectX 10 capable successor of the GeForce Go 7600 / 7700 for laptops and technically a higher clocked 8400M GT. The performance is slightly above the 7600 / 7700 and, therefore, it can represent DirectX9 games fluently. For DirectX 10 effects, the power of the card is not sufficient.
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.
The Core 2 Duo T7500 is a Merom based Core 2 Duo with 4MB Level 2 Cache. It is positioned in the middle class (in 2009) and performs on par with a modern P7550 or Turion II Ultra M640/M660.» Further information can be found in our Comparison of Mobile Processsors.
15-inch display variants are the standard and are used for more than half of all laptops.
The reason for the popularity of mid-sized displays is that this size is reasonably easy on the eyes, often allows high resolutions and thus offers rich details on the screen, yet does not consume too much power and the devices can still be reasonably compact - simply the standard compromise.» To find out how fine a display is, see our DPI List.
With this weight, a laptop is rather heavier than average. Devices in this range shine more with screen size and performance than with mobility.
