Performance in Real-Time Strategies

Perimeter

Due to high pixel shader performance, RADEON X1600 XT proves quite fast in real-time strategies. At least it doesn’t fall that far behind RADEON X800 XL in Perimeter game, in both: pure speed and eye candy modes. I think it could have performed even better than that if it only had more TMUs. I am strongly confident that by limiting the number of texturing units to only 4 ATI created a potential serious bottleneck for its RV530, which is in our case connected with the very low fillrate. High GPU frequency can partially make up for that, but it is not enough in some cases. Note, however, that the Perimeter results were taken manually, so they may be not absolutely exact.
