Fixed T&L Emulation

With only 1 light source RADEON X1600 XT yields to RADEON X800 PRO, though mostly in higher resolutions.

The same scene lit by 8 lights is also of no problem to the new RADEON X1600 XT, even though RADEON X800 PRO is still a little bit faster. You should keep in mind that the performance of RADEON X800 PRO was tested on a different platform, so it is not quite correct to compare these results against the performance of graphics accelerators with PCI Express interface. Moreover, as we have already mentioned, the results obtained from RADEON X1000 family in 3DMark 2001 SE do not seem trustworthy at this point.

5 vertex processors of the RADEON X1600 XT in the point sprites scene perform almost as fast as the 6 vertex processors of the RADEON X800 PRO. There is only one major difference: the vertex processors of the new solution work at much higher frequency. Also it has a more efficient memory controller – despite the 128-bit memory bus, its performance doesn’t drop down as greatly as that of the RADEON X800 PRO when the resolution increases.
