Where can I see ES version of Athlon 64 *2?

As everyone knows, each product's process maybe contain engineering sample.
For example, there is word "ES" printed onto Intel's CPU.

How about our AMD's?
Where can we see this information?

Do you need this http://cbid.amdclub.ru/ (Central Brain Identifier) and http://www.cpuid.com/cpuz.php ?

I hope so…

Aren´t those CPUs only for testers? If you bought that CPU in a normal shop, can´t be an engineering sample (ES)
