DailyTech reviewed an early sample of ATI's upcoming Radeon X1950 Pro graphics card.  ATI has equipped the Radeon X1950 Pro with 36 pixel shaders and 12 pipelines on a new core that is essentially a stripped down R580. Here's some info:

Overall gaming performance with the Radeon X1950 Pro and Radeon X1900XT 256MB is very close. Although the Radeon X1900XT 256MB has a slight performance advantage in most games, it's not as big of a jump as the Radeon X1950XTX over the Radeon X1950 Pro. A couple of factors can contribute to the close performance numbers of the Radeon X1950 Pro and Radeon X1900XT 256MB. Two possible reasons include the Radeon X1900XT's 256MB of video memory isn't enough or the 48 pixel-shaders are excessive for the selected games. Nevertheless the Radeon X1950 Pro performance is quite promising.

Power consumption with the 80nm die shrink is quite impressive. Under load the Radeon X1950 Pro manages to consume a mere 225 watts-54 watts less than the Radeon X1900XT 256MB. While the Radeon X1900XT 256MB delivers more pixel shading power, the Radeon X1950 Pro offers slightly better performance-per-watt in gaming.

ATI's upcoming Radeon X1950 Pro looks quite promising considering the lower power consumption and near Radeon X1900XT 256MB levels of performance. The use of a single-slot cooler also makes the Radeon X1950 Pro more attractive for users with limited slot expansion capabilities. There's also the internal CrossFire connector that allows future upgrade to CrossFire slightly easier and less wasteful since it only needs another Radeon X1950 Pro instead of hunting down a Radeon X1900 CrossFire Edition.
