Athlon or Thunderbird?

[Guest]

Hey - I just bought an Athlon 850 processor from an online vendor - I purchased an 850 socket a thunderbird. I was just looking at the chip and it has a date of 1999 on the chip - how do I tell if this in indeed a Thunderbird version or just a plain old Athlon?

Thanks!

The classic Athlons were never make in socket form, so if you have a socket A Athlon, it's a T-bird.
