    GT740M: 128-bit and 64-bit performance difference?

    It seems that the Nvidia GT 730M and GT 740M are available in 64-bit versions, and 128-bit versions. I understand that a larger bus width is better, but considering the same card, how many of a difference in performance can be expected? In other words, just how much worse would the 64-bit GT740M be compared to its 128-bit counterpart?

    I've been using this to compare various GPUs, but this ranking doesn't distinguish between the 64 and 128 bit versions of the GT740M. Surely both can't be expected to give the same performance?

    Any help on the matter will be greatly appreciated! ^^

    the 64bit version will be 10% slower and more :) try to avoid it especially if your screen is past HD resolution..

    64bit? pffft haha give me a break.

    What is even the purpose of having a 64bit version? Save money on silicon I guess. Profit profit profit. Pathetic is what I call it.

    Don`t ever buy 64bit. I`m pretty sure you will se huge differences between 64bit vs 128bit when you enable more graphical goodies in the games. Don`t pay attention to much on the benchmarks. They are usually 720p with no antialiasing and such.

    This is something Im worried about too, in my case I ended up with the 1GB version. Also I wouldnt worry about going passed 768p as it seems to be designed with that resolution in mind.

    According to notebook check there is a 20-30% performance difference. Performance was better than I expected, not high end but it should manage medium-high at low resolutions and you might be able to overclock it.

    i see that the asus *56cb (128bit) version is the best or 2nd best score out there, the 64bit bus is just a big big fail in nvidia strategy !
