When I saw that table just now, I had no idea whether Nehalem is newer
and more advanced than Penryn, or the other way around. I also have
no idea if "Core i7" is newer than "Core 2 Duo" or not.
I'm not a typical user: I know quite a lot about x86 architecture;
I just haven't kept up to date enough to know the code/model names.
Typical users will know less about them.
It's only from seeing the G1/G2/G3 order that I guess they are listed
in ascending order of functionality.
Naturally, if I were choosing one, I'd want to choose the one with the
most capabilities that works on whatever my host hardware provides.
