A second option is that the new Poulson core is an out-of-order design. This is complementary rather than mutually exclusive, with simultaneous multi-threading, so both options are possible. However, since Itanium was specifically conceived to avoid out-of-order execution, this seems a little less likely – it would definitely be a philosophical retreat, although possibly a wise one.


Is that really unlikely?

The original IPF designers were probably pretty strongly opposed to OoO but things change and what's more the people involved now quite likely feel very differently about this having their own experiences and background to draw from (it's not clear of the people who did this are they former EV8 people or not).

Avoiding OoO probably made a lot more sense 10 years ago than it does now.
