ATI Mobility Radeon HD 530v: Renamed HD 4350 graphics card and therefore an entry level GPU with DirectX 10.1 support.

Only some 3D games with very low demands are playable with these cards.

» Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.


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.


T6670: Entry level Core 2 Duo based on the Penryn core. Similar to the C2D T6600 but with VT-x Virtualization and higher temperature specification.» Further information can be found in our Comparison of Mobile Processsors.
