Your timeline is interesting to me because it suggests you think Intel started to pull ahead with in 2006 Clovertown (quad core MCM with northbridge memory controller) rather than with Nehalem or Westmere (integrated memory controllers) in 2009-10.
- walrus01 7y agoIt has been quite a long time since I laid hands on any of these, but to refresh my own memory: https://en.wikipedia.org/wiki/Opteron https://en.wikipedia.org/wiki/Opteron section 3.1 and 3.2 there has the original single core opterons. At the time in 2003/2004 they ran circles around the single core xeons, where a two-socket motherboard meant two cores. This was the same era as the Socket 604 Xeons.

Intel's much better prefetcher let them get away without having an integrated memory controller. https://www.anandtech.com/show/2045/5 https://www.anandtech.com/show/2045/5
- thedance 7y agoClovertown was basically two Core 2 Duos in a multi-chip module, and capable of multi-socket system configs. The AMD fans at the time snickered at the MCM, for being a hack and a workaround, not a "true" quad core part. AMD didn't launch the "true" quad core server part until a year after Clovertown. That was the "Barcelona" Opteron 23xx, and it was terrible, and broken. To me that was when AMD faded.
