Winchester or not, how to find out?

[Person]

Hello everyone.
I have what seems a problem to me. I bought what supposedly was supposed to be an Athlon 3500 Winchester. But somehow I have many doubts about that being an actual winchester. How can I find that out excatly? I tried searching for pictures of both to maybe a find some kind of a number on the proc to compare to mine, but all the pictures I find seem to have slightly different numbers.
Thanks very much for any info!

Well if you have it installed and running in your motherboard just run CPU-Z

If it's .09u it's winchester, if it's .13u it's newcastle.
