Well...even though Athlon will continue for some time..as the budget chip, AMD expects that half of their production will be the hammer family of chips within 18 months from NOW. So, like Intel, they plan a pretty quick transition to the new chip. Unlike Intel with the P3 and PS Celerons, though, they won't be discontinuing their Athlons within 18 months as far as I can tell.
The weird thing is AMD will have a chip (Athlon) as their budget desktop and notebook chip competing against the P$ Celeron, yet it will perform much closer to the P4 Northwood. Hammer will be competing against Northwood and supposedly will outperform it handily. When Prescott arrives, Hammer will supposedly perform about the same over all, but then AMD will be bringing in their own .09 micron shrink and we don't know what improvements that will bring. So, the end of 03 and into 04 is anyone's guess.
