Thoroughbred has a short life span

I believe that the Tbred was just a move by AMD to make sure their .13 micron process works. From roadmaps I have, the Barton core will be introduced in the second half of this year, leaving hardly anytime for Tbreds to seep into the market.

Look for Barton Athlons with 512K of cache and most likely a FSB boost. And yet even after Barton, the Clawhammer will be right on its toes.
