I don't think so, its got SSE, that's it.
BGWG as in Boogie Woogie.
Katmai has an improved L1 cache controller, resulting in performance roughly 3% higher than Deschutes, clock-for-clock. Can't remember where I read that though.

All you probably want to know about Katmai.
Pentium III = Pentium II + SSE

K6-2 was initially known as K6 3D.
3DNow support was dropped with Bulldozer (2010). It had a long life but it was not very popular.
