NVIDIA GeForce Go 6400 Image NVIDIA NV44 A2 Image
The GeForce Go 6400 was a graphics card by NVIDIA, launched in February 2006. Built on the 110 nm process, and based on the NV44 A2 graphics processor, in its GF-GO6400SQ-N-A2 variant, the card supports DirectX 9.0c. The NV44 A2 graphics processor is an average sized chip with a die area of 110 mm² and 75 million transistors. It features 4 pixel shaders and 3 vertex shaders, 4 texture mapping units and 2 ROPs. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support). NVIDIA has placed 32 MB DDR memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 400 MHz, memory is running at 350 MHz.
Its power draw is not exactly known. GeForce Go 6400 is connected to the rest of the system using a PCIe 1.0 x16 interface.
