To some extent, ATI's R300 and R400 series is more popular
than the R500 (and now R600) series for Linux users. The R300/400 series
has a reliable open-source driver and while the performance of the X.Org
Radeon driver lags behind ATI's binary driver, it's currently the
fastest for offering open-source 3D performance on dedicated graphics
cards. With the cards being around much longer, they are also much
cheaper and have become somewhat popular for Linux desktops that can
power Compiz and Beryl "eye candy" effects. However, it's just
not the R500 and R600 series that receive a nice performance boost from
the new ATI/AMD Linux driver, but so does the R300/400 series. Using the
fglrx 8.41 driver on this older graphics hardware will allow for a
sizable performance improvement compared to the older binary drivers.
Much of AMD's focus is on the R500 and R600 series, as is our focus, but
we've completed some benchmarks comparing the new and old fglrx drivers
using an ATI Mobility Radeon X300 64MB and ATI Radeon X800XL 256MB
graphics card.
