The Stream Processor was a professional graphics card by AMD, launched in 2006. Built on the 90 nm process, and based on the R580 graphics processor, in its R580 XTX variant, the card supports DirectX 9.0c. Since Stream Processor does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The R580 graphics processor is a large chip with a die area of 352 mm² and 384 million transistors. It features 48 pixel shaders and 8 vertex shaders, 16 texture mapping units, and 16 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). AMD has paired 1,024 MB GDDR3 memory with the Stream Processor, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 594 MHz, memory is running at 648 MHz.
Being a dual-slot card, the AMD Stream Processor draws power from 1x 6-pin power connector, with power draw rated at 165 W maximum. Display outputs include: 2x DVI, 1x S-Video. Stream Processor is connected to the rest of the system using a PCI-Express 1.0 x16 interface. The card measures 241 mm in length, 111 mm in width, and features a dual-slot cooling solution.
