The Voodoo4 4000 AGP was a graphics card by 3dfx, that was never released. Built on the 250 nm process, and based on the VSA-100 graphics processor, the card supports DirectX 6.0. Since Voodoo4 4000 AGP does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The VSA-100 graphics processor is an average sized chip with a die area of 112 mm² and 14 million transistors. It features 2 pixel shaders and 0 vertex shaders, 2 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). 3dfx has paired 16 MB SDR memory with the Voodoo4 4000 AGP, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 166 MHz, memory is running at 166 MHz. Being a single-slot card, the 3dfx Voodoo4 4000 AGP does not require any additional power connector, its power draw is rated at 15 W maximum. Display outputs include: 1x VGA. Voodoo4 4000 AGP is connected to the rest of the system using an AGP 4x interface.
