ATI Radeon 32MB SDR

by Anand Lal Shimpi on October 13, 2000 4:46 AM EST

UnrealTournament is a very CPU limited benchmark and doesn't take full advantage of neither ATI nor NVIDIA's Hardware T&L engine, thus the minimum frame rates are very similar across the board here at 640 x 480 x 32.

Other than the Voodoo4 4500, most of the contenders performed similarly on average as well at this resolution. The GeForce2 MX held onto a 4% lead over the Radeon SDR.

With minimum frame rate numbers we can see that the Radeon SDR doesn't allow the frame rate to drop below 34 fps throughout the course of the demo while the GeForce2 MX let's it slip an 42% lower down to 24 fps. Let's see if the average frame rate tells the same story.

Unlike the Quake III Arena and MDK2 scores, we see the Radeon SDR outpacing the GeForce2 MX, even in the average frame rate numbers at 1024 x 768 x 32.

We know that UnrealTournament makes some very heavy use of textures, and thus the more efficient Z-buffer management on behalf of the Radeon SDR combined with its higher fill-rate gives it the advantage over the GeForce2 MX. The card however is still outperformed by the Voodoo5 5500 and the GeForce DDR.

At 1600 x 1200, you can't expect the minimum frame rate of the Radeon SDR to be too high...

...however on the average, the Radeon SDR is once again looking more like the GeForce DDR which has twice it's memory bandwidth instead of the GeForce2 MX which has the same amount of memory bandwidth as the Radeon SDR.

As we showed at the beginning of the benchmarks, without HyperZ, the Radeon would be struggling pretty bad here.
