The GeForce4 MX 420 was a graphics card by NVIDIA, launched on February 6th, 2002. Built on the 150 nm process, and based on the NV17 graphics processor, in its MX420 variant, the card supports DirectX 7.0. Since GeForce4 MX 420 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The NV17 graphics processor is a relatively small chip with a die area of only 65 mm² and 29 million transistors. It features 2 pixel shaders and 0 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 paired 64 MB SDR memory with the GeForce4 MX 420, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 250 MHz, memory is running at 166 MHz.
Being a single-slot card, the NVIDIA GeForce4 MX 420 does not require any additional power connector, its power draw is not exactly known. Display outputs include: 1x VGA, 1x S-Video. GeForce4 MX 420 is connected to the rest of the system using an AGP 4x interface.
