ATI Mobility Radeon HD 4650: The Mobility HD 4650 is based on the Desktop 4650 architecture, but features a lower clock rate of memory and core. Depending on the core clock (450-550MHz possible) and the used memory (DDR2, DDR3, GDDR3 with 600-800 MHz possible) the mobile 4650 can show a different performance. The current consumption of the chip alone ranges from 15-25W. Features Avivo HD video features.

Non demanding games should be playable with these graphics 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.
