How fast GMP can be on Opterons?

Because today is the AMD Opteron launch day I'm wondering how fast this new 
chip can work with GMP.

I see some impressive data at :

1) Latency for a 64x64 bits mul: 4 cycles.
2) A mul can be dispached every cycle
3) A 64 bit add every cycle

In an ideal world it could be more than 4 times faster clock by clock than 
current Athlons, what is remarkable. 

Well, time will say.
