I didn't mean to be rude earlier - I was just disappointed that the review didn't have the Barton clocked at the exact same speed/FSB/etc as a Tbred. I am just looking for a review/preview where both chips are clocked at the exact same settings, so we can obtain some more concrete results about the performance difference between the two chips.
Ideally, clocking a Tbred-B and a Barton both to, say, 1.73Ghz/133FSB/166Memory and benchmarking, and then again at ~2 GHz/166FSB/166 (or 200) memory would be really helpful for isolating the L2 cache as the only performance altering factor between the steppings.
