Well, the 64-bit extension is essentially a RISC design except for the
instruction encoding.  And you get twice as many registers as in 32-bit
mode.  Not really difficult to optimise for such a design, nor hard to
implement an efficient core based on a clean RISC archicture ... in
particular with just 16 registers.
