NVIDIA GeForce 8400M GT: NVidia GeForce 8400M GT is the DirectX 10 capable successor of the GeForce Go 7400 for laptops and technologically a slower 8600M GS video card. Not suited for DX 10 games in high details.
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.
Slow clocked dual core processor based on the Merom-2M core without virtualization functions.
