Two. When it says "per processor" it is referring to a processor socket.
You need to download the PUR - Product Use Rights document. It goes into this kinda stuff in mind-bending detail.

We're looking into buying a copy of Windows Server 2008 R2 Data Center (that's a mouthful) for a new beefy server we have... but I need clarification on the licensing... It says you need to buy a license "per processor". Well, that could mean several things. In my case, I have a Dual Socket system, each filled with a Quad Core Xeon, with Hyperthreading so there are two threads per core. So, do I need to buy 2, 8, or (*cringe*) 16 licenses? Anybody know where on Microsoft's licensing website it clearly states this missing detail? Thanks in advance. --Matt Ross Ephrata School District ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
