A new 3.0 GHz processor finishes the same tasks faster than a seven-year-old 3.8 GHz processor with the same number of cores. How is this possible?
Un nouveau processeur à 3,0 GHz accomplit les mêmes tâches plus vite qu'un processeur de sept ans à 3,8 GHz doté du même nombre de cœurs. Comment est-ce possible ?
Answers
AThe benchmark must be wrong, because a higher clock always winsLe test de performance doit être faux, car une fréquence plus élevée gagne toujours
BThe older processor must have been infected with malwareL'ancien processeur devait être infecté par un logiciel malveillant
CThe newer design does more work per clock cycle (higher IPC)La nouvelle architecture fait plus de travail par cycle d'horloge (IPC plus élevé)
DClock speed is measured differently in newer processorsLa fréquence est mesurée différemment sur les processeurs récents
