There is NO advantage installing a 64 bit OS on a 32 bit CPU that has
extended features to EMULATE AMD 64 bit instructions. Other than memory
address space and a few other things that will never be warranted on
today's laptops.
Stick with 32 bit Fedora on all intel CPU platforms except itanic. You
will be fine.
Having said that, I would also propound that the opposite is true for
AMD 64 bit CPU platforms. You can lose up to 15 percent (from my own
personal tests) performance by running a 32 bit made for intel
instruction set on AMD CPUs, because it has to EMULATE 32 bit instructions.
Could you please provide some documentary evidence for your assertion that AMD64
processors EMULATE [your emphasis, not mine] 32 bit instructions?
