The Riva TNT2 M64 was a graphics card by NVIDIA, launched on October 12th, 1999. Built on the 250 nm process, and based on the NV5B graphics processor, in its Riva TNT2 variant, the card supports DirectX 6.0. Since Riva TNT2 M64 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The NV5B graphics processor is a relatively small chip with a die area of only 90 mm² and 15 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). NVIDIA has paired 16 MB SDR memory with the Riva TNT2 M64, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 125 MHz, memory is running at 143 MHz.
Being a single-slot card, the NVIDIA Riva TNT2 M64 does not require any additional power connector, its power draw is not exactly known. Display outputs include: 1x VGA. Riva TNT2 M64 is connected to the rest of the system using an AGP 4x interface.
