re: It is you who is not realizing that only a very special algorithm can keep busy all 8 FP units all time, and this algorithm is definitely not all over the SPEC benchmarks.

No, it is you who is forgetting that OVER THE ENTIRE SPEC RATE BENCHMARK, "result" scales almost linearly in number of CPU's on Opteron processors.
