“Back when the Radeon X1000 ‘R500’ series support finally
arrived for Linux, it came six months after the hardware was
actually launched and the Linux performance was down the drain. In

the earlier Radeon X800XL and was clobbered by the NVIDIA GeForce
7800GTX being as much as four times faster. As we have been sharing
all day, the fglrx 8.41 Linux driver finally turns the table where
not only the Radeon X1000 performance is finally in order but all
of their supported product families received a very nice
performance boost. Four months after the availability of the Radeon
HD 2900XT, the 8.41 fglrx driver now supports the R600 product
family under Linux. We have multiple Radeon HD 2000 “R600″ GPUs at
hand for testing, but in this article we are focusing upon AMD’s
current flagship model, the Radeon HD 2900XT 512MB. The performance
of the Radeon HD 2900XT under Linux is certainly astonishing after
the previous performance shortcomings by ATI/AMD…”
