Core Duo has 2 64-bit SSE2 ports, not 1.

As for the closer than expected performance delta between C2D and CD, I put it down to two things:

1) Merom is FSB limited at 667, far moreso than Yonah.

2) Yonah was already a very efficient high IPC processor. Actually, it was even faster than the K8 clock for clock in everything but FP intensive apps.
