CPU speeds have not changed much in about a decade but that does not mean that the current GHZ barrier will never be passed. There are indications that THz transistors are possible at room temperatures see http://www.tgdaily.com/content/view/36946/113/ http://www.tgdaily.com/content/view/36946/113/ and http://www.technologyreview.com/read_article.aspx?id=17368&ch=infotech&a=f http://www.technologyreview.com/read_article.aspx?id=17368&#...
