Actually, the RISC vs CISC argument is a bit more complicated than has been mentioned.
Each approach has its advantages, for instance, CISC can create denser code with a larger number of available instructions.
But frankly, I don't favor either approach right now, as long as it works, who cares how?
And some cpus are a hybrid of both concepts.
For some time now, AMD cpus have run X86/X64 instructions with a RISC core.
An Amiga with both an FPGA based 68K accelerator and a PPC processor would be ideal as it would allow us to run both legacy and NG code.
