    Default 3GB Nvidia 555M vs 1GB Nvidia 640M

    Hello,

    3GB Nvidia 555M vs 1GB Nvidia 640M

    I am getting Dell XPS 17 (Sandy Bridge) & Samsung Series 7 (Ivy Bridge) for the same price.

    However, I am more interested in Samsung, as it has last tech, slim, stylish etc

    Now, question is how do you compare Nvidia 1GB 640M vs 555M 3GB

    If 640M is little better than 555M, then I think I should go with dell XPS 17

    Waiting for some help.

    Regards

    They're close, the 3gb in the 555m is a gimmick.

    If The samsung is has a 640M and NOT a 640M LE then it is much faster STOCK than a 555M

    Overclocked though, the 555M GDDR5 and 640M DDR3 are a stone's throw from each other. But if the samsung 640M is a GDDR5 version then it is the better choice.

    And Avoid the 640M LE because that's slower than either

    So,
    640M GDDR5 > 640M DDR3 = 555M GDDR5 > 555M DDR3 > 640M LE
    MSi GE620dx | i3-2310M | 8GB | GT 555M (GF116 128-bit DDR3) @ 900/1800/900 3DMark11: P1915

    Thanks bobuy00

    I am actually interested in this one.
    Amazon.com: Samsung Series 7 NP700Z5C-S01US 15.6-Inch Laptop (Silver): Computers & Accessories

    However, there is no news on GPU whether it is on DDR3 or DDR5. I read in reviews that it's DDR5 while Samsung.com/us & amazon.com live chat representative both told me that GPU is at DDR3.

    So, I am much confused in it. If you have any info about it, please share.

    The 640m is quite a bit faster then the gt555m and takes similar power consumption to a gt 525m.

    Guy here confirmed that it is DDR5.

    Very nice.

    This is my first Samsung laptop & I hope it will not regret me like many other Samsung products in my house.
