The Radeon X1900 GT was a graphics card by ATI, launched in May 2006. Built on the 90 nm process, and based on the R580 graphics processor, in its R580 XL variant, the card supports DirectX 9.0c. The R580 graphics processor is a large chip with a die area of 352 mm² and 384 million transistors. It features 36 pixel shaders and 8 vertex shaders, 12 texture mapping units and 12 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 256 MB GDDR3 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 575 MHz, memory is running at 600 MHz.
Being a single-slot card, the ATI Radeon X1900 GT draws power from 1x 6-pin power connectors, with power draw rated at 75 W maximum. Display outputs include: 2x DVI, 1x S-Video. Radeon X1900 GT is connected to the rest of the system using a PCI-Express 1.0 x16 interface.
