GameSpot's James Yu breaks down the new Nvidia GPU: "The GeForce Go 7800 GTX, a 24-pixel pipeline chip based on Nvidia's GeForce 7800 GTX desktop GPU architecture, is roughly twice as powerful as the 12-pipe GeForce Go 6800 Ultra but has the same power draw to maintain battery life. The GeForce Go ships with a 400MHz clock speed and comes with 256MB of memory."
Aside from the new GPU, the XPS M170 is virtually identical to the previous XPS Gen 2 model. The Dell XPS M170 will be available online later today, starting at $2,699.
