It uses a 128-bit memory interface and can scale up to a 2000 MHz memory clock. While these features put its raw processing power ahead of the nVidia GeForce GT 335M, they are very similar in most other ways. High definition video is handled through a separate PureVideo HD processor which can handle up to 1080p HD video standards, and 3D rendering is aided by NVIDIA PhysX technology. Graphic standards supported include DirectX 10.1, Shader Model 4.1, and OpenGL 2.1. 2-way SLI is supported allowing a second GeForce GPU to be linked and alternately share the load for faster graphics or shut down to save power.
