CPU mita: agogon, matsakaicin

Riga girma a tsaran kwamfuta masu amfani da suka ba su samu sanannen "tseren megahertz" cewa fãta shimfiɗaɗɗa tsakanin biyu manyan masana'antun na CPUs ga tebur kwakwalwa (wanda ba su sani ba - Intel kuma AMD) a nuna na Millennium. Its karshen zo kusa da 2004, a lokacin da shi ya zama na fili da cewa mita na processor - ba kawai halayyar da ke shafar ta yi.
