I always thought Conroe had fully pipelined FPU from looking at your article, but its not true. It still has the same FPU latency for FPMUL as its P6 derivatives. BTW, why would they take the legacy FPU to 128-bit anyway?? I think they are still 64-bits, exactly similar to Yonah. Barcelona did not change its FPU, only SSE units were enhanced, same is very likely true with Conroe.
