This question already has an answer here:

For Server 2012 Datacenter do they charge per 2 physical cpu or per 2 cores?

Example if I have an EVGA Classified SR-X motherboard with 2 Intel Xeon E5-2687W, 8 core cpus, will I only need to buy one Windows Server 2012 Datacenter ($4500) or will I have to buy 8 of them ($36,000)?

Ask your reseller, or check Microsoft's site. – mfinni Mar 24 '13 at 18:39
It's per processor, not per core. But why wouldn't you contact them directly instead of asking here? I've never understood why people post licensing questions here instead of asking the vendor directly. – joeqwerty Mar 24 '13 at 18:39

Thanks, and sorry I didn't notice that. I don't really want to spend thousands on MS software, the question was hypothetical for my blog. – Drtupw Vffe Mar 24 '13 at 18:50
@DrtupwVffe You can call a reseller without making a purchase... – MDMarra Mar 24 '13 at 19:54

A quick look at the documentation reveals that a single license of Standard or Datacenter covers two physical processors.

I am kind of surprised that a 50k user answers a question which the FAQ explicitely declares off-topic... 8-) – Hauke Laging Mar 24 '13 at 18:44

@HaukeLaging Just because something is about to be closed doesn't mean you can't throw a guy a bone once in a while if it's an easy answer :) It just so happens I've spent the last week up to my elbows in System Center and Windows Server licensing. – MDMarra Mar 24 '13 at 19:53
