NVIDIA GeForce Go 6600 NPB 128M Image NVIDIA NV43 A4 Image
The GeForce Go 6600 NPB 128M was a graphics card by NVIDIA, launched in September 2005. Built on the 110 nm process, and based on the NV43 A4 graphics processor, in its Go 6600 variant, the card supports DirectX 9.0c. The NV43 A4 graphics processor is an average sized chip with a die area of 150 mm² and 146 million transistors. It features 8 pixel shaders and 3 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 128 MB DDR memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 375 MHz, memory is running at 300 MHz.
Being a igp card, its power draw is not exactly known. GeForce Go 6600 NPB 128M is connected to the rest of the system using a PCIe 1.0 x16 interface.
