One alternative CPU model were the various Lisp machines.
A really amazing example, though, was Intel's first 32 bit CPU, the iAPX 432 [1] -- it was actually object oriented. And it supported garbage collection (like Lisp machines).
It was kind of beautiful from one point of view, but it was absurdly impractical and complicated and slow. It was an extreme example of CISC, and the (simple and fast) RISC revolution killed off such things. Well, the iAPX killed itself, but...
