I saw the i7's but I'm getting confused about dual core. Is the i7 thing a new speed instead of Mghz?
the Core I series comes in a series of different processor subfamilies, I3, I5, I7... and individual members of each of these has different specs. and they bridge 2 complete chip micr-architectures
and to make it even MORE complex, there's "Nehalem" Core I3/5/7 and "Sandy Bridge" Core I3/5/7.
here, easier than explaining it all, its kinda confusing how many models there are. http://en.wikipedia.org/wiki/Intel_Core#Nehalem_microarchitecture_based http://en.wikipedia.org/wiki/Intel_Core#Sandy_Bridge_microarchitecture_based
For instance, the Core I7 920-960 family were Nehalem microarchitecture based 2.67 to 3.33 GHz 4-core 8MB cache CPUs. The I7 970-990 are 6 core 3.2-3.5Ghz 12MB cache Nehalem (and obscenely expensive).
The I7-2600 is the new Sandy Bridge guts, this time with 3.4GHz, 6 cores
nehalem and sandy bridge CPUs require different motherboards.
The I5 and I3 are smaller/slower versions of the above. For instance, a Core I3-2100 is a "Sandy Bridge" 3.1Ghz 2-core
confused yet?
