Correct, basically, the P4 will need the fully-functional next-generation core (the current one had some features axed to meet production deadlines and size concerns) and a generation of SSE2-optimized softare to really show its potential. Meanwhile, Athlon chips are a dime-a-dozen by comparison and spank the P4 in most current apps

K6-3: The original 0.25µ variants were sold at 400 and 450MHz, a small batch of 500MHz versions did make it out the door. They did tend to run hot, and the absence of any redundant L2 cache columns lowered yields (i.e. if a die came out of fabrication with any bad cache cells -- which are a part more likely to be DOA -- the whole thing was scrap).

The K6-3s you are hearing a lot of people talk about right now are actually K6-3+ chips, and its near-relative, the K6-2+. Basically, as a filler for the laptop market until the mobile Duron comes out (this quarter, most likely) AMD released the "plus" chips, based on the K6-3 core but manufactured at 0.18µ for lower-voltage, cool running. The K6-3+ is basically a K6-3 core (256kB of on-die L2 cache); the K6-2+ offers 128kB of on-die cache but uses the same core -- thus giving AMD a place to downbin cores with faulty cach cells AND offer two 'grades' at the same time.

The "plus" chips use the Socket 7 interface, many Super 7 boards will work with them, and many of the "plus" chips were sold by OEM dealers -- mostly at the 450MHz rating. However being 0.18µ they overclock very well, with many hitting 600MHz and more out of the box.
