But it's not just a matter of wasting transistors and silicon. The ancient x86 modes are like old legacy code in a software package you have to maintain. They add complexity. Intel hasn't exactly been cranking out an endless series of bug-free chips lately. It might behoove them to make a line of chips which are pure x86-64.
