Two types of T-bird Bs?

Hey,
I'm getting a T-Bird B CPU for my Abit KT7a (1.2), and I'm planning on
getting a 2100, 2200 or 2400 (because I heard that for overclocking
they are all the same). When searcing for a way to tell weather or not
2100 and 2200 chips were Bs I found this website (
http://www.overclockers.com/tips00173/ ) that claims that there are
two types of T-bird Bs, quote:

"There are high-end and low-end TBredBs. They aren't all the same. The
high-end ones on average perform several hundred MHz better than the
low-end ones. Update 3/28/03: The gap between the two has narrowed
somewhat with the latest (week 8 and thereafter) "J" chips.
You can identify which type of TBredB it is by looking at code that
begins the second line of coding on the processor. If you see a code
like "AIUHB" that begins with the letter "A," that's a high-end
TBredB.
If you see a code like "JIUCB" that begins with the letter "J," that's
a low-end TBredB."

Is this true? And if it is then is the differnece significant when
overclocking?

Thanks

OK, These are Tbreds, as in thoroughbred core, not T-birds as in
thunderbird cores, but the tips are pretty much correct. The only problem
you may encounter now is that if you get a newer chip it may be completely
multiplier locked internally. To avoid this make sure the date code is
prior to 0338.
