Actually the point is really simple...hyperthreading produces a boost in speed and an extra thread to run background applications faster. If AMD has the know-how to incorporate hyperthreading technology into their processors they would be foolish not to economically and performance-wise....The truth of the matter is....they cant do it and maintain a bargain basement price for their products...and in all reality...I'm not 100% sure they have the know how or else they could be marketing a high end hyperthreading chip to compete with the xeon...or maybe they just don't want that extra money?
