The Graphics Xpression ISA was a performance 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. 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 shaders and 0 vertex shaders, 0 texture mapping units and 1 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). ATI has placed 2 MB DRAM memory on the card, 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. This device has no display connectivity, as it is not designed to have monitors connected to it. Graphics Xpression ISA is connected to the rest of the system using a PCI interface. Its price at launch was 249 US Dollars.
