Phenom or Opteron

I just bought an AMD processor. On the box it states that it is a PHENOM 8650. (The seals were broken under my eyes and showed me the markings on the top of Proco before installation), the seller is recognized as a serious (even if I live in a country where there is virtually no legal provisions for consumer protection).

When verifying by CPU-Z, the processor has been recognized as a OPTERON 1386.

I would like to know which one is authentic? Does anyone has seen this type of incident?

Thank you for your help.

This is a CPU-Z bug in my opinion, because it's clear that it has 3 cores, 2MB of L3 cache and code-named "Barcelona" to own such Phenom.

Conclusion, your processor is indeed a Phenom 8650.

So if I understand, there are other type of phenom 8650. Do you have a link that gives more details on this point?

No there's only one type of Phenom X3 8650, the others are X3 8450, 8750 and 8850.
