This just adds another layer of confusion. Sure, these two models are based
on the same core. But giving the illusion that they are somehow the same will
lead to tears before bedtime:

1) They each took a snapshot of that core design on different dates, so there
   are logic differences.
2) Feature fuses will be different
3) Microcode will be different
4) BIOS will be different
5) "uncore" is different, so anything implemented outside of the core
    will be different.
