ATI Mobility Radeon HD 545v: Renamed HD 5145 GPU (which is a slightly high clocked HD 4570) and therefore an entry level graphics card with DirectX 10.1 support.
Only some 3D games with very low demands are playable with these cards.

520M:
The Core i5-520M has only 3 MB L3 Cache (compared to the I7-640M) and clocks between 2.4-2.93 GHz (Turbo Mode). Thanks to Hyperthreading, 4 threads can be processed simultaneously. An integrated graphics card (GMA HD 3150) and a DDR3 memory controller are also included in the package.
