I'm not totally sure what the author's referring to, but hyper threading is coming back. Of course, the Sun Niagara chip does 4 threads per core, rather than two, and IBM's Power series has been doing SMT (hyper threading by another name) for some time. http://anandtech.com/cpuchipsets/intel/showdoc.aspx?i=310... talks about 8 core Intel CPUs that will support hyper threading per core for 16 threads per CPU.
