Relief Rendering and Other Tests

RADEON X1800 XT doesn’t cope that well with the EMBM relief rendering. Besides, it appears no faster than RADEON X1800 XL in lower resolutions, which automatically indicates that the results are incorrect and require verification.

During Dot3 relief processing, RADEON X1800 XT competes with GeForce 7800 GTX, while RADEON X1800 XL runs as fast as its predecessors.

This test allows us to estimate how well-balanced the CPU-driver-GPU connection really is. Its engine uses real physical model, pixel shaders version 1.1 and vertex shaders version 1.4. From the better balance prospective, the leader here will be GeForce 6800 Ultra: it has the flattest graph of all. Speaking about the fps rates, the first place will belong to RADEON X1800 XT, and the second one - to GeForce 7800 GTX, and the third one to RADEON X1800 XL.
