Hadoud76, Hyperthreading is nothing to get excited about. It is simply Intel's marketing name for SMP (symetrical multi-threading). In certain applications it provides a 10% performance increase, in other applications it causes a 10% performance decrease, and in many cases, it makes no difference at all.
It's all marketing... I'll give it to Intel, they have some of the best marketing people in the industry. AMD chose not to use SMP in their processors because in many cases it reduces performance (the 2 logical processors fight over shared resources of a single die)
To be fair... the PDEE really is "something", it is a high performance processor. But like the rest of their CPU line, AMD has a processor that outperforms it. (that may change with the release of the Conroe cored Pentiums, but that remains to be seen and until then Intel still finishes last)
