The following excerpts are from Agner's The microarchitecture of Intel and AMD CPU's.

On Pentium M: "The retirement station can handle three fused _uops_ per clock cycle." (Page 66.)
(Core2 is similar, but as you say adds another uop to that.)

On K8: "the retirement is limited to three
_macro-operations_ per clock cycle." (Page 120.)

("A macro-operation in AMD terminology is somewhat similar to a fused micro-operation in Intel terminology." (Page 108.))

So, the AMD's can retire upto 6 micro-ops, while Core2s 4, but some of those can be a fused one. In case all 4 is fused (if it's possible), then it's like there were 8 -- I would think on average it's like there were 6...
