The Radeon 9550 was a graphics card by ATI, launched on October 1st, 2003. Built on the 130 nm process, and based on the RV350 graphics processor, in its RV350 LX variant, the card supports DirectX 9.0. Since Radeon 9550 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The RV350 graphics processor is a relatively small chip with a die area of only 76 mm² and 60 million transistors. It features 4 pixel shaders and 2 vertex shaders, 4 texture mapping units, and 4 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 paired 64 MB DDR memory with the Radeon 9550, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 250 MHz, memory is running at 200 MHz.
Being a single-slot card, the ATI Radeon 9550 does not require any additional power connector, its power draw is not exactly known. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. Radeon 9550 is connected to the rest of the system using an AGP 8x interface.
