Gigabyte GA-MG400 Matrox G400 AGP

The Unreal Tournament engine limits the performance of all of the contenders here, but it does help to illustrate the benefit of having that extra 16MB of SGRAM. The 16-bit performance of the MG400 is excellent here, but switching to 32-bit color drops the performance of the MG400 a good 35%, and this is only at 640 x 480.

We get a similar situation at 800 x 600, the strong D3D performance of the G400 core puts the MG400 ahead of the two NVIDIA competitors in 16-bit rendering, but the switch to 32-bit color takes its toll out on the 16MB of SGRAM on the board.
