NVIDIA announces GeForce Go 7800 GTX
Today NVIDIA takes the wraps off its GeForce Go 7800 GTX, a mobile version of its G70 graphics processor. Like the desktop GeForce 7800 GTX, the Go has 24 pixel pipelines, eight vertex units, a 256-bit memory bus, and about 300 million transistors. However, the Go 7800 GTX runs at slightly slower 400MHz core and 550MHz memory clock speeds. Otherwise, it supports the same features as the GeForce 7800 GTX, including DirectX 9, Shader Model 3.0, PureVideo, and transparency antialiasing.
In addition to all the bells and whistles you'd expect from a GeForce 7-series GPU, the GeForce Go 7800 GTX also features a suite of power management features that NVIDIA gathers under the PowerMizer 6.0 umbrella. PowerMizer 6.0 includes provisions for dynamic clock gating, aggressive clock and voltage scaling, and the ability to shut down components, such as a TV output, when they're not in use. The GeForce Go 7800 GTX can also scale its PCI Express link from 16 lanes down to just one to save power, and even drop the link into a special low power state. All these power saving technologies allow the GeForce 7800 GTX to fit within the same 65W TDP as the GeForce Go 6800 Ultra that it replaces, making it easy for notebook vendors to drop the chip into existing form factors.
If you want to get your hands on a notebook with the GeForce Go 7800 GTX, systems should be available from Alienware, ABS, Dell, Eurocom, Evesham, Falcon Northwest, Hypersonic, Prostar, and Voodoo PC today. Of those notebooks, all but the ones from Dell will also work with NVIDIA's next ForceWare graphics drivers, allowing users to get bug fixes and feature updates without having to wait for new drivers to filter through their notebook's manufacturer.
