NVIDIA GeForce 256 SDR Image NVIDIA NV10 A3 Image
The GeForce 256 SDR was a graphics card by NVIDIA, launched in October 1999. Built on the 220 nm process, and based on the NV10 A3 graphics processor, the card supports DirectX 7.0. The NV10 A3 graphics processor is an average sized chip with a die area of 111 mm² and 17 million transistors. It features 4 pixel shaders and 0 vertex shaders, 4 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 32 MB SDR memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 120 MHz, memory is running at 143 MHz.
Being a single-slot card, the NVIDIA GeForce 256 SDR does not require any additional power connector, its power draw is not exactly known. Display outputs include: 1x VGA. GeForce 256 SDR is connected to the rest of the system using an AGP 4x interface.
