Whats the newer chip for the xbox 360? Falcon or Jasper?

Jasper is the newest chip but I hear they still put falcons in the new 360's. I bought one 3 months ago and have had no problem with mine. there are different things to look at to know which one is the jasper.. lower voltage and what not.. if you are buying a new one from the store it will be a jasper. hope this helps
