NVIDIA GeForce Go 6800 Ultra: Gaming On Dell's Inspiron XPS Gen 2
Introduction, Specifications & The Notebook
About three weeks ago, we tested a new Acer notebook powered by ATI's Mobility Radeon X700. With our testing complete, we found the Mobility Radeon X700 to be a well-balanced mobile GPU that offered very good performance, in a thin and relatively light form factor. Then, a few days after that article went live, we were contacted by representatives from NVIDIA and given an opportunity to test a different sort of animal. NVIDIA told us they'd be releasing a new mobile GPU meant for high-end, desktop replacement notebooks. What we ended up getting our hands on was a new Dell Inspiron XPS Gen 2 with a GeForce Go 6800 Ultra pushing the pixels.
The GeForce Go 6800 Ultra incorporates all of the technology found in NVIDIA's desktop NV4x architecture, like PureVideo, UltraShadow II, and PS 3.0 support, plus some mobile-specific features of its own. The specifications listed below, and the information in this article, will bring you up to speed on what the NV4x architecture brings to table. When you're done perusing that, read on to see what NVIDIA has in store for gamers on the go; you won't be disappointed.

We got to spend some time with Dell's new Inspiron XPS Gen 2 to test the NVIDIA GeForce Go 6800 Ultra. The new Inspiron XPS Gen 2, is a much more portable notebook than the original XPS. The Gen 2 is thinner, lighter (about 9lbs), doesn't generate as much heat, and is much more attractive than the first XPS notebook. There are green lights interspersed behind all of the grills, which make the unit glow when powered up and the lid is adorned with a brushed metal, rippled sheath. At the heart of this unit is an Intel Pentium M 2.13GHz processors, 1GB of DDR2 533 RAM, Intel's Mobile i915 Express chipset, and of course the NVIDIA GeForce Go 6800 Ultra. In this particular notebook, the GeForce Go 6800 Ultra's core is clocked at 450MHz and its 256MB of GDDR3 RAM is clocked at 550GHz (1.1GHz DDR). That makes the GeForce Go 6800 Ultra the second highest clocked NV4x based product we've ever tested. Only the elusive GeForce 6800 Ultra Extreme Edition, with its 600MHz (1.2GHz DDR) memory, is clocked higher.
The Inspiron XPS Gen 2 has a 17" LCD, with a native resolution of 1920x1200. We found this display to be surprisingly adept at interpolating lower-than-native resolutions. The typical blur associated with running an LCD below its native resolution wasn't very pronounced when viewing the Windows desktop and while gaming at lower resolutions, blurring was hardly noticeable at all.
