    GDDR3 - GPU/video memory
    DDR3 - RAM/memory

    GDDR3 is a video memory type used in graphics cards, while DDR3 is a RAM/memory type that will eventually replace DDR2 RAM in laptops when the Montevina platform is released later this year. DDR3 memory already compatible in some desktop motherboards though.

    That's probably just a typo. GDDR3 is obviously exclusive to graphics cards, while DDR3 is exclusive to RAM, as far as I know. Maybe you read DDR2? Some NVIDIA cards have DDR2 graphics memory, like my Vostro's 8600M GT.

    Yeah and graphics cards are SDR, DDR, DDRII (not DDR2 [that was the Jedec diff at the time] but everyone still writes DDR2 because no one remembers the diff), GDDR3, GDDR4, GDDR5.

    Desktops are SDR, DDR, RDRAM, DDR2, DDR3

    The only potential near term cross-over is if either nV or AMD ever finally adopt XDR.
