I doubt that dual ported VRAM is commonly used any longer. Nowadays the bandwidth required to read out the frame buffer is miniscule compared to the bandwidth required to render 3D scenes on it, so there is no real benefit from a special port that is used for framebuffer readout. —Preceding unsigned comment added by 130.236.55.37 (talk) 12:42, 10 June 2009 (UTC)[reply]

I have seen dual port RAM (though not VRAM) in the wild. In the particular usage I saw, it was done as a conscious simplification of FPGA development, designed to ensure FPGA developers did not need to be aware of bus contention between the FPGA and the test chips that support it. I may venture a guess that, once the product comes off of the test board and into production, the DPRAM would be replaced with single port RAM, without altering the FPGA in any way.
