i386 & i686


Hi

Can anyone let me know what exact difference between i386 and i686 architecture based machine.
Both suppose to be using 32 bit OS ?

Thank you

http://en.wikipedia.org/wiki/Intel_80386

Both are 32-bit. You don't have to care, and should go for the i686 version of whatever, unless you have an actual 80386 chip around.

The i686 has a lager set of instructions to draw from or the i686 has all the i386 instructions plus extras. All i686 computers will run i386 code just fine but the reverse is not true. A 386 or 486 will not be able to run code that was built for a 686.

Yes, there are 32 bit. I don't known all differences, mainly are instruction sets. You can get more info on every architecture from wikipedia.

if you are unsure about which architecture to use ,you can use i486 , but it will detect only one cpu if you have many cores.

i use i686 . it should work on computers made after 2000 i think ..
