This gives it a 50% advantage in SPEC FP_rate compared to the 2700K and equalling the SPEC INT_rate of the same 2700K.

So it clearly does have an impact. (or the submitted score of zambezini is crippled... or the opteron score is rigged..)
The 6204 is a special model for specific data stuffing tasks. Clocks aside it has much more uncore stuff per 4 cores than Zambezi for 8 cores.
Zambezi:
4M/8C
4x2MB L2
1x8MB L3
2xDDR3

Opteron 6204:
2x1M/2C
2x2MB L2
2x8MB L3
8xDDR3
