The XGPU-B was a graphics card by NVIDIA, launched in November 2001. Built on the 150 nm process, and based on the NV2A graphics processor, the card supports DirectX 8.1. The NV2A graphics processor is an average sized chip with a die area of 128 mm² and 57 million transistors. It features 4 pixel shaders and 2 vertex shaders, 8 texture mapping units and 4 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 64 MB DDR memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 233 MHz, memory is running at 200 MHz.
Being a igp card, its power draw is not exactly known. XGPU-B is connected to the rest of the system using an AGP 4x interface.
