ATI unveils Mobility Radeon X1800, X1800 XT
Not shipping, though...
ATI has just unveiled its new Mobility Radeon X1800 and X1800 XT notebook-oriented graphics chips, both fabbed at 90nm and incorporating more than 312m transistors, used to provided respectively 12 and 16 Shader Model 3.0 pixel shaders and eight vertex shaders.
Both GPUs support eight-channel DDR, DDR 2 and GDDR 3 memory, connected via the X1000-series' usual ring bus. They're both native PCI Express x16 parts, and support not only ATI's Avivo video imaging technology, but the company's PowerPlay 6.0 energy saving system.
The X1800 is clocked at 450MHz, while the XT runs at 550MHz. ATI did not disclose memory clock speeds. It did say the X1800 and X1800 XT will be found in products from Alienware, Boxx, Eurocom, Fujitsu Siemens Computers, Hypersonic, Rock, Savrow and Voodoo PC.
ATI didn't address availability either, but Rock - one of the first vendors to announce a machine based on the new GPU family, and favoured with a mention in ATI's press statement - said its Xtreme CTX machine will ship "from April 2006", undoubtedly a guide to X1800 availability. ®
