    How important is the memory bus on a GPU?

    What's the standard Memorybus (Bit)?
    Would the 32bit Memorybus in a GeForce Go 7200 have a large impact to decrease performance compared to the 128bit Memorybus in the ATI Mobility Radeon X1300? Thanks.

    EDIT: Sorry if this should actually have gone in the Gaming forum, I didn't realize when I started the thread.

    Very much, the X1300 is stronger than 7200, Go to my 3DMark05/06 guide in the signature and see.

    The memory bus is important, as it governs the amount of data that can sent to the memory, and this affects performance. For example, some Mobility X1600 graphics cards can have a 64-bit memory bus, which limits their performance by quite a bit. Higher end graphics cards like the nVidia Go 7900 S, have larger 256-bit memory bus.

    performance would drop some 30% if you reduce the memory bus by one half
