No, it uses 48-bit addresses and some flag bits, but it can use a 64-bit
selector rather than two 32-bit ones, improving the performance
significantly.
Please also note that PAE only has 36-bit addresses, allowing for up to 64GB
of RAM, while AMD64 allows for 256TB, theoretically.
Well, s/RAM/address space/
