Since Linux support for the Radeon X1000 "R500" series was introduced some 17 months ago, there has been a performance imbalance. The past fglrx drivers have worked, but they've had a difficult time competing with the competition presented by NVIDIA and their Linux driver when it comes to the frame-rate performance. Though as we have been sharing in all of our articles today, the new ATI/AMD Linux driver will be made available in the coming days and it offers some striking performance improvements. In our Mobility Radeon X300 testing, the new driver allowed Doom 3 and Quake 4 to run at playable frame-rates, which simply wasn't possible with the previous 8.40.4 fglrx driver a month ago! The Radeon X800XL performance was also improved significantly, which allowed it to outperform the NVIDIA competition. Now onto the Radeon X1000 family, as you can probably suspect, there are massive performance improvements to be found with these graphics cards as well. In this article we have tested the Radeon X1300PRO, X1800XL, X1800XT, and X1950PRO with the new ATI Linux driver and have found significant performance improvements.
