Not quite true -- it's actually ">4GB per process", as x86 CPUS (P6 and
newer) have supported up to 64GB (IIRC) through use of the PAE
extension. Only high-end server motherboards ever supported this much
RAM though.
The "no benefit without >4G RAM" rule held... until x86-64 came along.
x86-64 vs x86 doubles the number of GPRs available (from 8 to 16 --
other 32/64-bit CPUs typically have at least 32) This can make an
incredible difference in performance, especially on computationally-
intensive code.
