The Graphics Ultra was an enthusiast-class graphics card by ATI, launched in January 1992. Built on the 800 nm process, and based on the Mach8 graphics processor, in its 38800-1 variant, the card does not support DirectX. Since Graphics Ultra does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The Mach8 graphics processor is a relatively small chip with a die area of only 90 mm². It features 1 pixel shader and 0 vertex shaders, 0 texture mapping units, and 1 ROP. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support). ATI has paired 1 MB VRAM memory with the Graphics Ultra, which are connected using a 32-bit memory interface. The GPU is operating at a frequency of 10 MHz, memory is running at 10 MHz.
Being a single-slot card, the ATI Graphics Ultra does not require any additional power connector, its power draw is not exactly known. Display outputs include: 1x VGA. Graphics Ultra is connected to the rest of the system using a PCI interface. Its price at launch was 899 US Dollars.
