Hello, I am buying a simple laptop, 15", T4300 or 4400, 2-4gb memory, 160-320 gb Hard drive. I use it for email, web browsing, and minor office functions. My question is: " Will I notice the difference in performance between the 32 bit and the 64 bit version of Win 7 Home Premium".
Doesn't the 3.2GB RAM limitation only hold for 32bit XP and Vista? I thought win 7 doesnt matter if its 32bit or 64bit.
Nope, it has to do with how much RAM the OS can address. 2^32 = 4294967296 bits. Divide that by 1024 twice and it gives you 4096 Megabytes, which is the theoretical maximum of addressable RAM for a 32bit OS. This is as much a limitation for Windows 7 32bit as it is for Vista and XP.
concur - very litle to no performance differnce between 32 bit and 64 bit Win 7 on a laptop.
Most laptops come with 32 bit preinstalled with less than 4 gigs ram, 4 gigs = 64 Bit preinstalled. Howerver there has been a shift toward 64 bit on laptops with 2 gigs preinstalled and have a max of 4 gigs.
As also stated by others Most apps that you will use are still 32 bit.
Real life diff, if you upgrade to 4 gigs of ram, is that with 64 bit Win 7 you will have 4 gigs available for the operating system and programs. With a 32 bit (in a laptop) you will have about 3.5 gigs available for the operating system and programs due to memmory mapping. Will 1/2 gig make a diff - For you NO.
Bottom line - Unless you have a preference, Flip a coin, or take what comes preinstalled and enjoy.
PS I have both. Laptop 4gigs ram - 32 bit win 7. My coin came up tails (realy my preference for laptop.
