The GeForce4 420 Go was a mobile graphics chip by NVIDIA, launched on February 6th, 2002. Built on the 150 nm process, and based on the NV17 graphics processor, in its 420 Go A5 variant, the chip supports DirectX 7.0. Since GeForce4 420 Go 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 32 MB DDR memory with the GeForce4 420 Go, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 200 MHz, memory is running at 200 MHz.
Its power draw is not exactly known. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. GeForce4 420 Go is connected to the rest of the system using an AGP 4x interface.
