The processor is made up of 32 CUDA cores which work with 512 MB of DDR 2 memory. The memory works with the processor in a 128-bit interface at 16 GB/s to move data to and from the processor as fast as possible. 3D standards supported include DirectX 10, Shader Model 4.0, and OpenGL 3.0. To increase processing in graphically intense games that use these standards 2-way SLI is enabled, allowing for a second GeForce card to be linked to the original. The PureVideo HD engine is used to decode high definition video signals quickly and efficiently.
