Yes and no, K6-3 biggest problem it suffered from the same lousy FPU that the K6-2 had. This time around the Athlon's FPU is its strong point. The barton could be a really nice upgrade path for dual systems as well.
It's not what they tell you, its what they don't tell you!
1)In relation to the size of the K6-3, Barton is tiny. Yes, it's bigger than TBRED but it's not sufficiently bigger that it's manufacturing costs are going to hurt AMD. Plus, UMC is going to be manufacturing Barton because FAB30 is gearing up for Hammer. Barton expense is not an issue.
2)K6-3 was, in some areas, much better than the K6-2, Pentium & Pentium II. The K6-3 suffered from the same weak FPU of the K6-2 and an inability to scale to competitive clock speeds. Barton has a very strong FPU and, as Tbred B has shown the Athlon still has headroom in it. I predict that, if needed, AMD could push Barton to 2.8GHz based on how Tbred B rev. is scaling.
3)Barton is late but not too late for it to effectively compete. AMD needs to crank up the clock speed though.
I like the Pentium IV, I really do! And it's so versatile. You simply won't find a more stylish or decorative key chain ornament or paperweight.
