> Because they are selling magic and brands, not concrete features.

And because it's completely pointless to sell concrete features for certain components. If they boast the Ghz number it will be relatively easy for competitors to produce higher figures. Ghz don't mean anything unless you take into account all kind of details (architecture, throttling...) that no one except really detail-oriented reviewers will go through and that will bore 90% of the users. Hence the bragging on the name.
