In my first version, I tried to match each model because inside each
sub family, some are faster than the other.
According to Internet sources
like http://en.wikipedia.org/wiki/Radeon_R700 and
HD4350 and HD4550 have quite the same horse power, based on RV710.
HD4650 and HD4670 have quite the same horse power, based on RV730.
HD4700 is reported by AMD to be based on RV770, while HD4770 is based on
HD48xx uses RV770 but not HD4890 which uses RV790.
According to benchmark, HD4770 is "faster" than HD4830.
Upcoming (rumored) HD4790 based on RV790 is said to be faster than
HD4850 or even HD4870.
Note that the patch doesn't take account of HD48xx X2 card model based
on R700 which are reported to be way faster than all the others.
So the point was to match card and sort them by "power" instead of
But it seems not doable since OpenGL renderer string like "ATI Radeon HD
4800 Series" is not useful to distinguish between HD4890 and HD4850 :(
