ATI Radeon X1650 PRO Image ATI RV535 Image
The Radeon X1650 PRO was a graphics card by ATI, launched in August 2006. Built on the 80 nm process, and based on the RV535 graphics processor, the card supports DirectX 9.0c. The RV535 graphics processor is an average sized chip with a die area of 131 mm² and 330 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 600 MHz, memory is running at 700 MHz.
Being a single-slot card, the ATI Radeon X1650 PRO does not require any additional power connector, its power draw is rated at 44 W maximum. Display outputs include: 2x DVI, 1x S-Video. Radeon X1650 PRO is connected to the rest of the system using a PCIe 1.0 x16 interface.
