By now you should be familiar with ATI's Radeon 9800 Pro chip. Here's ATI's official feature set:
Separating From the Pack
The Radeon 9800 Pro is not a huge technical step over the 9700 Pro, but offers a higher clock speed which gives a huge bump in performance. Core speed on the 9800 Pro is 380 MHz vs. 325 MHz from the 9700, while memory speed has been upped to 680 MHz DDR from 620 MHz. The R350 core is nearly the same as the R300 core other than these differences, with only minor changes in the feature set.
The huge heat pipe cooling sink.
What makes Sapphire's 9800 Pro Atlantis Ultimate Edition different from other 9800 Pro cards? As mentioned earlier, it's all in the cooling. Sapphire's model offers an effective, silent, and unique Atlantis "heat pipe" (by Zalman) to cool the VPU. This device trades the basic active cooling solution (heatsink/fan) for a passive one. The Zalman cooler allows a liquid to boil and evaporate, pushing vapor through the tube to the rear side of the card. There the liquid cools and condenses, where the process then repeats.
On either side of the card, decorative RAM sinks can be found as well.
Someone spent a lot of time making this card pretty.
From any angle, the Atlantis Ultimate Edition appears to be a technical marvel. The heat pipe design is nearly flawless except for the amount of space required to install it into a case. Its effectiveness has yet to be proven to us at this point...
