Nope, they are faster simply because they are newer
Core development gives more efficient cores

Nope, the pointers are bigger but the memory path is wider

They handle magnitudes more memory then a 32bit system.
See my previous post. Try running a 22Gb render in 32bit.

I can't argue your point in costs because I don't know what 64bit systems
cost where you live, but here it's close to a no-brainer.

benefits are more speed and more memory
