I have a confirmation that acer laptop v3 571g has Nvidia 730m with 128 bit memory bus bandwidth interface. What do you think about other OEMs Specially Dell, will they implement the same 128 bit interface or 64 bit interface as specifications tend to differ among OEMs Nvidia itself says so, also Notebookcheck.net indicates interface as 128/64 bit. I have this doubt because Indian variants are often inferior. If Dell is Playing cheap on its customers than I will refuse the delivery of my inspiron 14 Laptop.
P.S. As per as I know GK107 (Keplar) architecture has 128 bit bandwidth only but if other variant of GT 730m has 64 bit memory interface then it is not even keplar "which means two variants of this card were fitted in laptops as specifced by different OEMs" though Nvidia officially announced the presence of the 64 bit varient recently along with other 700m family.
