ATI Radeon X1600 PRO Image ATI RV530 Image
The Radeon X1600 PRO was a graphics card by ATI, launched in October 2007. Built on the 90 nm process, and based on the RV530 graphics processor, in its RV530 PRO variant, the card supports DirectX 9.0c. The RV530 graphics processor is an average sized chip with a die area of 150 mm² and 157 million transistors. It features 12 pixel shaders and 5 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 placed 256 MB GDDR3 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 500 MHz, memory is running at 390 MHz.
Being a single-slot card, the ATI Radeon X1600 PRO does not require any additional power connector, its power draw is rated at 41 W maximum. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. Radeon X1600 PRO is connected to the rest of the system using a PCIe 1.0 x16 interface.
