Help on memory interface

Could you guys please tell me about the difference of 128bit memory interface or 256bit interface on a graphics card? Your help would be greatly appreciated.

Thank you,

  1. 256 bit is wider so you cna send twice as much data through it

    example:

    you are going from A to B, at rush hour
    now the road there is only 2 lanes long but there over 500 people on it, there ofre a 20 minute trip takes you 1 hour

    the next day they widen that same road so now you have 500 people on a 4 lane road, so now a 20 minute trip takes you 15 minutes

    so you see a wider memory interface means more data sent and faster

  3. and gddr5 is twice as fast at the same buswidth and clocks than ddr3
    so
    5@128bit@900MHz is as fast as 3@256bit@900MHz
