Haha, I saw that and asked the same thing at Anandtech. These server chips are slight tweaks to consumer chips. They work with server chipsets [and ECC RAM as you caught!]; don't know what else differs. There aren't yet "large" Xeons (E5 or E7) on Broadwell or Skylake, only Haswell. The table of Haswell chips from Wikipedia is the best handle I can quickly get on the how the server chip line works: https://en.wikipedia.org/wiki/Haswell_(microarchitecture) https://en.wikipedia.org/wiki/Haswell_(microarchitecture) - E5 and E7 have more cores and L3 cache - They also support more sockets (the model numbers start 2, 4, or 8 according to how many sockets they support) - They're released a lot later: the first Haswell chip was in June 2013, but all the E7s in the tables are listed as May 2015. And Haswell is v3 so Broadwell is v4 and Skylake is v5. If this roadmap is right, larger Broadwell chips will come next year and large Skylake Xeons might not be until 2017(!): http://www.theplatform.net/2015/05/26/intel-lets-slip-broadwell-skylake-xeon-chip-specs/ http://www.theplatform.net/2015/05/26/intel-lets-slip-broadw... I was vaguely aware that architectures would mature before working their way up the server line, but not of how long that pipeline was. Anyway, guess we shouldn't hold our breath!
