Instructions per clock

I sat down and figured out the Instructions Per Clock of a set of x86 architectures. You can use it to compare the raw single threaded performance of any architectures.

e.g. a 2.5GHz Core 2 ia about the same as a 3GHz Athlon 64 x2

Pentium 1	1.1
Pentium MMX	1.2
Pentium 3	1.9
Pentium 4 (Wil)	1.5
Pentium 4 (Nor)	1.6
Pentium 4 (Pre)	1.8
Pentium 4 (Gal)	1.9
Pentium D	2
Pentium M	2.5
Core 2		3
K6 II		1.1
K6 III		1.3
Athlon B	1.9
Athlon C	1.9
Athlon XP	2
Athlon 64	2.3
Athlon 64 X2	2.5
Via C3		0.85
Via C7		0.9
