I thought the Core2 chips were actually multiple single-core processors on a single slab, which would make that true of all Core2 machines (not just Xeons).  I was pretty deep in Nehalem details when it first came out and was under the impression that microarchitecture was Intel&#x27;s first true multi-core chip (as in, the cores were actually integrated on the die).  Could be wrong, though, since I never delved into the Core2 architecture.
