This is Kim.
I'd like to know about reading CPU code.
Before writing this post, I've found so many blog about reading CPU code.
Most of blogs said that E5-2620 means first 2 = CPU generation 2 is sandy bridge and next 620 = performance(It is good performance that the number is higher.)
According to blogs information, E5-2620 CPU is sandy bridge.
But I searched this CPU in intel site.
the Xeon E5-2620 v4 CPU is Broadwell CPU.
So I am very confuse now.
How can I read Xeon CPU code ?
And what is Westmere ?

The E5-2620 is a Xeon processor. However, there have been 4 versions of this processor since 2012.

The closest I can get to a Sandy Bridge 2620 is this:

Westmere is a family of Xeon processors: http://ark.intel.com/products/codename/63616/Westmere Products formerly Westmere EP
And, lastly, you may find this helpful in identifying markings on your processor:

Lots of information. I hope you find it helpful.
Thank you very much to Al Hill for all the comments posted previously.
Hi, KJ.Kim, Thank you very much for joining the Intel® Graphics communities.
I hope the information posted above was useful for you, it contains all the documentation related to the processor codes and how to identify the markings on it.
Any further questions, please let me know.
Al Hill's answer was very useful to me. But I have additional questions for CPU Code.
"Xeon E# (Product Line # (Product Family) V# (Version)"
Q1. What is the meaning of CPU number ?
- In the Product Family, first # means Maximum number of CPUs in a node.
It means that CPU Core ? I don't understand well.
Q2. What is the meaning of Socket Type ?
- I also don't understand well.
According to http://ark.intel.com/compare/92986%2C83352%2C75789%2C64594 Intel® Product Specification Comparison page.
E5-2620 Processor has 4 version.
Version 1, 2, 3 has 6 core and 4 has 8 core even they are same processor line(2620).
It makes me more confused.
KJ.Kim, Excellent. Yes, the maximum number of CPUs in a node, refers to the quantity of processors that can work together in a system, for example, the Intel® E5-4669 v4 processor, will support a system that works with 4 processors at the time, as you can confirm on the link below under "max cpu configuration":
In regard to the socket type, I will do further research on that matter, and as soon as I get any details I will post all the information on this thread.
Any questions, please let me know.
KJ.Kim: I just wanted to let you know that I just received an update on the research we were doing on the Intel® Xeon E5 product line, and actually the 2nd digit differentiates the socket type, for example:
E5-2400 series used and older socket, 4 = (socket B LGA 1366)
E5-2600 and 4600 series used the other socket, 6 = (socket R LGA 2011)
Any questions, please let me know.
