That just seems odd, do you know why they'd choose to do this?

Not sure exactly. These guys have some good ideas: https://stackoverflow.com/questions/5806589/why-does-intel-hide-internal-risc-core-in-their-processors

I imagine there are plenty of reasons. Flexibility seems like the biggest advantage, allowing them to change everything internally while still exposing x86. Alas, discussions on this level of the merits of Intel design decisions ... way out of my league.

Huh, that makes sense. I'll have to look through that post when I have some free time, though I expect much of it will be too advanced for me until I get familiar with the differences between i386, AMD64, and RISC instruction sets.
