80bit x87 multiplication (FMUL) on Merom* is indeed not fully pipelined. However 64-bit SSE2 (MULSD/MULPD) multiplication is fully pipelined. So MULSD has two times higher throughput over Banias/Dothan/Yonah while MULPD has four times higher throughput.

Don't you mean "the same FPU throughput"?

I don't like when people use the name "Conroe" to describe Intel's new microarchitecture. Conroe is just a name of desktop variant of Merom core.
The use of the name "Barcelona" instead of Hound or Greyhound is only marginally better.
