Notebook graphics as good as a high-performance desktop PC's are promised by ATI which today unveiled its latest graphics chip, the Mobility Radeon 9000.

Dell, HP, NEC and Fujitsu Siemens have signed up to use the chip in their notebooks, as have Taiwanese companies Asus and Compal which make notebooks for a number of other brands.

When it comes to fast realistic visuals, notebooks with onboard graphics usually lag way behind desktop PCs with dedicated graphics cards that sport a high-performance processor and fast memory.

The Radeon 9000 has an on-chip frame buffer of 64MB and uses several proprietary software technologies to provide top-notch graphics performance. The software takes advantage of the latest features in Microsoft's DirectX 8.1, so gets the best out of the most recent 3D games.

"You shouldn't have to look at 640x480. That's not gaming, that's looking at big fat pixels," said ATI product manager Darren McPhee at the chip's launch.
