If your CPU has only a single core, it's officially a dinosaur. In fact, [URL="http://www.pcworld.com/businesscenter/article/151092/indian_team_designs_intels_first_true_quadcore_chip.html"]quad-core computing[ is now commonplace; you can even get laptop computers with four cores today. But we're really just at the beginning of the core wars: Leadership in the CPU market will soon be decided by who has the most cores, not who has the fastest clock speed. What is it? With the gigahertz race largely abandoned, both AMD and Intel are trying to pack more cores onto a die in order to continue to improve processing power and aid with multitasking operations. Miniaturizing chips further will be key to fitting these cores and other components into a limited space. Intel will roll out 32-nanometer processors (down from today's 45nm chips) in 2009.
