Here is the cpu info of a more recent quad core Intel.
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Xeon(R) CPU X3220 @ 2.40GHz
stepping : 7
This model is 10 cpu designs ahead, but still part of the i686 family,
of course these 10 designs do not show the separate Pentium/Xeon/Pro
tree lineages. I think they gave up giving the steppings nick names
a long long time ago.
indeed, "Xeon" further confuses things, this is simply a brand name for
a 'Server' CPU. There have been Xeon's that were Pentium-III based,
then Pentium-4 based, and now new ones like that are Core2Duo based.
and, further confusing things, the Pentium-4 variants weren't really P6
core based, they had a completely different internal architecture known
as NetBurst, but Intel decided not to give it a seperate family
designation for who-knows-what reason. The newest "Core" based CPUs
are in fact derived from the Pentium-M laptop processor, which in turn
was based on a redesign of the P6 (Pentium-III) guts, discarding the
Netburst architecture.
