Calling Core duo a Pentium III core, esp. when talking about microarchs, is a slight misrepresentation. Of course it was way closer and more of a derivative of the PPro descendants. But P6 did not vary a lot between PPro and P III, while before reaching Core Duo it went through Pentium M, and then enhanced. So yeah, it looks like more a Pentium III than a Pentium 4, but it was certainly not just a "hack [gluing] pentium 3 cores together"

Also Netburst was not that bad. It was a dead-end, yes, but on some markets it could compete with what AMD had.

Plus implementing SMT is not necessarily extremely easy compared to SMP, especially when you evolve designs.

And anyway, Intel shipped HT way before AMD shipped the Athlon 64 x2...
