1) maybe, maybe not. Variance works off of a lot of different factors 2) Intel historically has had absolutely insane yields on their server parts. The large server dies have an absolutely insane lvl of redundancy and harvest ability. I think you severely underestimate the yields on Intel server parts. 3) And no one would want to. 10Gbe? It is all but dead in the server market. New deployments are being done with 40Gbe/25Gbe/50Gbe/100Gbe. USB 3.1 in the server space??? 128 lanes of PCIe is simply unneeded in this space or pretty much any other per socket (and before you scream about NVMe, no one wants to route that many lanes from the socket to a backplane, real NVMe deployment are done with PCIe switch chips). And I'm pretty sure that Xeons will support more memory per socket. The MCM really doesn't buy you anything over monolithic except not having to tape out a separate die. And that's the reason that AMD is doing it, because they are resource constrained, not because it is better. If they weren't resource constrained, they be doing a larger monolithic die.
