ATI Mobility Radeon HD 3430: Entry level low end dedicated graphics adapter with slower clock rates than the HD 3450.
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.
T6400: Entry level dual core processor based on the Penryn core with only 2 MB level 2 cache and a low clock speed.» Further information can be found in our Comparison of Mobile Processsors.
