Hi,
Whats the difference between 32 bit and 64 bit?

I jus got both Ubuntu 32bit and 64bit, but only 32bit was able to get thro to installation.


And in what way the performance differ?

Thx.
 
64bit can support over 3.2GB of RAM
There is also a 10-15% gain on some applications in 64bit instead of 32bit

Does your CPU support 64-bit?

A good general rule of thumb is: if you're unsure if you need 64-bit, you don't.

While it is the future, it's still a long way off from becoming the mainstream standard.

The finite amount that 32 bit supports is 4gigs but other components take up some ram so this actual number varies between machines.
 
So, theoretically 4096 Mb, but practically some systems 32 bits see less than 4 Gb. I have AMD Phenom 9600 and its work at Vista Ultimate 64 Bits without any problem
 
I dont think Linux is under the same RAM usage restrictions as windows. I believe 32 bit and 64 bit both support 3 gigs, could be wrong, but i think thats right.
 
Just keep in mind that the average user doesn't need more than 2 gigs of RAM, and really no more than 1-1.5 gigs if using XP or below.

Linux also has a Swap partition, which further negates the need to have obscene amounts of Physical RAM. I can run Ubuntu just as efficiently with 512 MB of RAM and a 2 Gig Swap partition as I can with 2 Gigs of RAM and a 2 Gig Swap. Unless I do some fairly hardcore compiling or have tons of things going on at once, it makes little difference in performance.
