The Mobility Radeon 9800 was a mobile graphics chip by ATI, launched in July 2004. Built on the 130 nm process, and based on the M18 graphics processor, the chip supports DirectX 9.0b. Since Mobility Radeon 9800 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The M18 graphics processor is an average sized chip with a die area of 281 mm² and 160 million transistors. It features 8 pixel shaders and 4 vertex shaders, 8 texture mapping units, and 8 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 256 MB DDR memory with the Mobility Radeon 9800, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 350 MHz, memory is running at 300 MHz.
Its power draw is not exactly known. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. Mobility Radeon 9800 is connected to the rest of the system using an AGP 8x interface.
