CES 2005 Nvidia has introduced its first mobile graphics chip with its AGP-style TurboCache memory management system.

The GeForce Go 6200 is pitched at mainstream thin'n'light notebooks, addressing the market segment below the gamer-oriented systems the already-available (http://www.theregister.co.uk/2004/11/08/nvidia_geforce_go_6800/) GeForce Go 6800 is intended for.

Like the 6800, the 6200 - along with a parallel offering, the 6250 - supports Nvidia's PureVideo hi-def video-oriented image enhancement technology. PureVideo leverages the three GPUs' support of DirectX 9.0 Shader Model 3.0.

However, the 6200 and 6250 also support TurboCache, a feature absent from the 6800. TurboCache allows the GPU to use main memory, accessed via the PCI Express bus, as video RAM, a technique originally included in the AGP spec.

Nvidia arch-rival ATI has just such a system of its own, dubbed HyperMemory. Both companies are pitching their respective new incarnations of the old AGP feature as a way to let notebook vendors save money (http://www.theregister.co.uk/2004/12/15/nvidia_turbocash/) by cutting the amount of memory their machines dedicate to the graphics chip.

Nvidia said Sony, for one, has agreed to use the new mobile GPU in a pair of Vaio notebooks. ®
