ATI Graphics Xpression ISA

The Graphics Xpression ISA was a performance-segment graphics card by ATI, launched in January 1995. Built on the 600 nm process, and based on the Mach64 graphics processor, in its Mach64 GX variant, the card does not support DirectX. Since Graphics Xpression ISA does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The Mach64 graphics processor is a relatively small chip with a die area of only 90 mm² and 1 million transistors. 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 2 MB DRAM memory with the Graphics Xpression ISA, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 40 MHz, memory is running at 40 MHz.

Being a single-slot card, its power draw is not exactly known. Display outputs include: 1x VGA. Graphics Xpression ISA is connected to the rest of the system using a PCI interface. Its price at launch was 249 US Dollars.
