NVIDIA Quadro DDR

Intergraph 3D ExerciZer

Intergraph's 3D ExerciZer is a good, low level, easy to use OpenGL test tool that one can use to look at how graphics cards handle specific operations under varying load conditions. This tool was used to investigate the texture handling performance of the Quadro DDR in comparison to the other cards.

The test output was put into chart form:

This chart shows the cards' measured  performance (frames per sec.) as a function of texture size. The Quadro cards ( DDR and SDR ) with 64 MB or memory clearly perform better once the texture size is in the range of about 16 MB - 48 MB.  This is one area where the Quadro cards with 64 MB of memory have an advantage over the 32 MB GeForce cards.
