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

IntroductionBack when we first took a look at the NVIDIA GeForce Go 6800 we mentioned that NVIDIA was able to run their part at much higher 450/600 clock speeds (the part we tested was running at 300/300). It was much easier for OEMs to drop graphics solutions into existing designs DTR designs using the Pentium 4 and GDDR1 RAM for the video card. Using the hot Pentium 4, much of the Thermal Design Power (TDP), the limit on how much power can be dissipated as heat, is taken up by things other than the graphics core. DDR1 also runs hotter than DDR3, and thus memory clocks are also limited by the thermal restrictions.
Today, Dell is introducing their Inspirion XPS Gen 2. The DTR notebook features a 2 or 2.13GHz Pentium M and a GeForce Go 6800 Ultra with 450/550 core/memory clocks. Rather than just ship their Go 6800 at the high core speed, NVIDIA has given it the Ultra moniker to differentiate the product.
The "new" GeForce Go 6800 Ultra graphics card is exactly the same as the original Go 6800, except that we are finally seeing it at the high clock speeds NVIDIA originally promised we would see. For an explanation of the differences between NVIDIA's mobile and desktop products, please see our initial review.
Aside from simply exchanging the Pentium 4 setup for a Pentium M, Dell has also invested more time in improving its thermal solution. The result is a thinner (it's still not thin), lighter (still feels like a brick) efficiently cooled desktop-in-a-notebook. NVIDIA informed us that the TDP for the chassis is 65W. This is not something we will see anywhere but the DTR segment. Most of the large TDP is taken up by the graphics solution, as Dothan based Pentium M processors and DDR2 system memory run at comfortable temperatures. The new Inspirion XPS Gen 2 is also Alviso based.
This is a fairly significant design win for NVIDIA as Dell's previous XPS graphics solution was ATI's Mobility Radeon 9800.
