http://www.game-debate.com/gpu/index.php?gid=757&gid2=113&compare=geforce4-ti-4600-vs-radeon-9200-series

is there a mac based comparison of these two?

I was doing some bench marking of the Gainwood Dual DVI( 4600Ti ) vs. R9200 with some odd results in OS 9 vs OS X.

So far I only tested JK2 and Quake III.

What I found so far is the R9200 is about 75% as fast as the 4600Ti, however when you run out of texture memory on the R9200  things come almost to a halt. You know 128Mb of VRam vs 32Mb.

Jk2 allows a setting for "Very High" textures, and it will bring the R9200 to it's knees, yet the 4600Ti breezes right on( not unexpected ).

The odd part comes with some of the results of the 4600Ti in JK2 OS 9 vs. 10.5.8. Same binary( Carbon ) under OS X is double the frame rate at the same setting, on the same hardware. Setting r_smp 1 doesn't seem to speed things up at all under OS X, even tho in Quake III based games it should off load the sound subsystem to the second CPU and be good for a 15%-20% gain in frame rate, but requires 10.1 or later, so no OS 9 support for SMP in JK2.

Not sure about other Quake III based titles, if SMP worked, ever, under OS 9.

Also, FSAA requires 10.2 in JK2, so no love there for OS 9. The only cards that supported FSAA under OS 9 was the Voodoo cards, and they my have only supported it in Glide games, not Open GL, but I don't know for sure.
