GeForce Go 6800 Ultra: Powering the Dell Inspirion XPS Gen 2by Derek Wilson on February 24, 2005 3:04 PM EST

Final WordsThe performance of the GeForce Go 6800 Ultra is unprecedented in the mobile space. Of course, while the mobility of a DTR system is always debatable, there's no doubt that scaling down powerful systems to this size has its advantages and appeal (especially when there is no sacrifice in graphics performance).
Without having a comparable comparison platform, we can't directly compare the Go 6800 Ultra and the desktop 6800 parts. It does seem clear that Go 6800 Ultra is at least as powerful as its desktop counterpart. Being limited by a less powerful CPU and still coming out on top in more than a couple tests is very impressive.
We would still like to setup a direct comparison between the Go and desktop 6800 parts in order to examine the part on a clock for clock level. We would like to better determine the impact of the power saving features in mobile part. The 50MHz speed bump from the desktop to the Go 6800 Ultra seems only possible due to power saving features. On the desktop NVIDIA tried the 6800 Ultra Extreme, but most vendors were only able to get their parts to about 425 (and this in a virtually thermally unlimited environment). Of course, performance is one of the tradeoffs in the balance, and a clock for clock comparison in the same platform would give us some good data on the GeForce Go line's efficiency compared to the desktop.
It's also useful to note that the new XPS Gen 2 did not get as hot to the touch. It seems Dell has done a better job of getting heat to move outside the system in spite of all the power packed into the chassis. We only had one night with the system, so we were unable to perform an in depth analysis of the system.
