ATI debuts Radeon X1800 range

Graphics chip specialist ATI has come up with a new range of GPUs aimed at the notebook market. The company is claiming that the new chips will offer notebook users blinding performance on their machines.

The company has announced two new chips known as the Mobility Radeon X1800 and Mobility Radeon X1800 XT mobile GPU based on the same R520 core as the desktop version of the X1800. Both chips are built for PCI Express-equipped machines and are fitted with 256MB of GDDR3 RAM and a new ring-bus memory controller.

The Mobility Radeon X1800 XT is fitted with 16 shader pipelines, eight vertex shaders and runs at 550MHz. The Mobility Radeon X1800 offers a slightly lower spec with 12 shader pipelines, six vertex shaders and runs at 450MHz. Both chips are built on a 90nm process.

The chips are also equipped with Avivo technology for high definition video and, according to ATI, offer full support for Catalyst Mobility, providing notebook users with access to the latest Catalyst drivers.

Notebooks with the Mobility Radeon X1800 series of graphics processors will be available starting 7 March. A number of companies have already announced products containing the new ATI silicon including Alienware, Boxx, Eurocom, Fujitsu Siemens Computers, Hypersonic, Rock, Savrow and Voodoo PC.
