  • Matrox G400 32MB DH or G450 16 MB DDR DH??

    Hello,
    I have the possibility to use either a Matrox G 400 32 MB Dualhead or a Matrox G450 16MB DDR Dualhead.

    The card is used in a buisness PC, where no real 3D performance is needed (maybe 6 times a year a opengl/d3d game has to run).

    Where are the differences between the two graphics cards in terms of usability, features, Dualhead, heat production, other and stability?
    Which card should I use?
    Matrox rox, S3 sucks!

    Are you using DVI? If not the G400 is the better choice.
    no matrox, no matroxusers.

      Both cards are AGP and Dualhead VGA (no DVI) because i am using 1 - 2 CRT monitors.

      @thop: why is the G400 the better choice?

        It is faster, has 32MB and supposedly better TV-Output.

          If you want to run the second head at higher resolutions (like, greater than 1152x864) at a decent refresh rate, you'll have to go with the G450.

            @ribbit:
            Is it because of the lower RAMDAC of the G400?
            How much has the G400 and the G450?

              I'm not Ribbit, but... Yes. Secondary RAMDACs for G400 and G450 are 135 and 230 MHz, respectively. The 64-bit DDR memory used in the G450 makes the card slower than the G400 (which has 128-bit SDR memory).

              More about the differences:

                It's because the G400 has a dedicated Maven chip for the second head, while the G450 does a lot of that work in software. You could sort of say that on a G450 the second head is "more like the primary display."

                  I thought the Maven was just a TV-out encoder/scaler?

                    Actually, doing the maths, the 135MHz secondary RAMDAC on the G400 should be fast enough for about 1280x960@72Hz. If you want to do any better than that, you'll need the G450.

                    The 230MHz 2nd head on the G450 should be good for about 1600x1200@80Hz.

                      afaik, the Maven also contains the secondary ramdac.

                        The secondary display on my G400 MAX is no where near as clear as the secondary display on either my G450 or my G550.

                          yes, the secondary ramdac on the G450/G550 is integrated into the core, and much better than the one in the Maven
