Thank you for contacting the Intel community.
The Intel® Xeon® Processor E5-2667 v2 is a multi core processor, you can see specifications here:
Thanks for your feedback. Indeed, my question was if the the processor is a multichip one or a single chip i.e. are the cores bundled on the same chip on a multiple chips?
Sorry if my question wasn't clear.
Are you asking about the number of Dies the processor was fabricated on? If so, according to this article it is either 6, 10 or 12. Take a look here and see if it's what you are asking. Intel Xeon E5-2697 v2 and Xeon E5-2687W v2 Review: 12 and 8 Cores If my assumption is right, I thought licensing was based on number of processors and physical/virtual cores, not on the Die. Would you mind providing a link to the Oracle document specifying the processor licensing requirements?
Thanks for your feedback. Here is how Oracle define a processor in case of Oracle Standard Edition (ref. http://www.oracle.com/us/corporate/pricing/databaselicensing-070584.pdf
When licensing Oracle programs with Standard Edition One, Standard Edition 2 or Standard Edition in the product name, a processor is counted equivalent to a socket; however, in the case of multi-chip modules, each chip in the multi-chip module is counted as one occupied socket.
I check the datasheet ((page 13) http://www.intel.com/content/www/us/en/processors/xeon/xeon-e5-1600-2600-vol-1-datasheet.html) of the processor and it is mentioned that E5-2667 v2 are "monolothic processor" getting me confuses what is exactly a chip? a die? a socket? in this case.
Here is my understanding of the Oracle processor requirements:
They are only concerned about how many sockets, how many cores and how many threads are in a box. Nothing to do with processor fabrication, such as a die, etc.
Sockets - refers to the physical place where you attach a processor to a system board. See this picture for example;
When Oracle refers to the number of sockets, they are referring to the number sockets populated with a processor in a box. So, a four 4-way box has four sockets populated with 4 physical processors. In your case, if you have a box with 4 sockets populated with an E5-2667 v2 processor, you’d have 32 cores and 64 threads.
If your box has only 1 E5-2667 v2 in the box, then you’re only required to license 8 cores and 16 threads. I am not sure if that means regardless of how many cores and threads are running, as not all cores and threads are active at all time. I am sure Oracle can clarify that for you.
Cores - refers to the number of cores in a processor. Since the E5-2667 v2 has 8 cores and it is a multi-threading processor, it has 16 threads.
This was my understanding too. But what get me confused is that they are doing a differentation between socket and chip in the Standard Edition case as you can see in the quote above from the licensing document.
"A processor is counted equivalent to a socket; however, in the case of multi-chip modules, each chip in the multi-chip module is counted as one occupied socket"
They are referring to the physical cores, so on a processor with multi-cores, whether it is 2, 4, 8 or however many, each core would be counted as a separate processor. So they don't care about socket, but how many cores on the processors attached to the socket/s. It is a legal verbiage issue. But Oracle can certainly verify that.
Yes but in the same document they are talking about core in case of Enterprise Edition licensing. So I think mulichip and multicores are different concepts...
You know, you may be on to something I was clueless about till today. I will research this further and hopefully an official Intel response would shed some light on the issue real soon. Glad you stayed on the issue and I will stay posted..

I just came across this post. Exact same question as yours Is Intel Xeon E5-2699v3 processor multi-chip module?
More pertinent posts to your question:
Thanks again for persisting, I got to know something new, even though I still don't fully understand it, I have a good lead to do more reading on.
Thank you very much @SahaluS. I appreciate your help.
As you said, I hope we get a response from someone in Intel. For the link it concerns v3 family, I m not sure it is the case for the v3 family too..
You are welcome D@nyal.
One more link for you that discusses multi chip (MCM) if you feel like digging in, kind of very technical. Intel migrates to desktop Multi-Chip Modules (MCMs) with 14nm Broadwell. As for me, it is good enough to know there's such a thing as MCM.
This is a very good discussion. I have seen questions regarding MCMs for several years now, and the information regarding them is limited.
I have done a quick search for some threads and various XEON chips. Below are the links to the threads, the link to the processor, and a NO or ?? regarding whether it is a MCM or not. I am just providing the information as is. SahaluS , you have provided some good information. Perhaps you would be willing to create a thread discussing this subject, with a list of chips that have been discussed previously? It would be a great source of information regarding this subject.

Yes. This is a great idea.
Waiting for a confirmation from Intel...
