My guess is 40% better Winstone

Pravin,

Winstone performance is largely limited by memory latency. I believe that gaining 40% on Winstone would be close to impossible without using a faster DRAM. The MP bus on K7 is likely to actually slow down Winstone because of extra clocks for snooping.

<<Anyone care to guess what the performance improvement of the K7 will be over the K6-2?

My guess is 40% better Winstone and 60% better general floating point
performance; clock for clock.>>

Unlike Intel, AMD is not an idiot. Intel new processor or product is not guaranteed to run faster than their older. For examples:

1) Pentium Pro is SLOWER than Pentium under Window95.
2) Celeron is SLOWER than Pentium in business applications.
3) New Pentium 300MHz mobile will be SLOWER than old PII mobiles.

AMD products on the other hand:
1) K6 is faster than K5
2) K6-2 is faster than K6
3) K6-3 is faster than K6-2
4) K7 is faster than K6-3
It is a no brainer.
