Intel Core i7-3940XM

Intel 3940XM

L'Intel Core i7-3940XM il processore quad-core per portatili più veloce (al momento del lancio nel Settembre 2012) ed è il successore dell'i7-3920XM. Grazie all'Hyperthreading, i quattro cores possono gestire fino ad otto threads in parallelo con un conseguente miglior utilizzo della CPU. Ogni core offre una velocità base di 3.0 GHz ma può effettaure in incremento dinamico del clock rates con il Turbo Boost fino a 3.7 GHz (per 4 cores attivi), 3.8 GHz (per 2 cores attivi) e 3.9 GHz (per 1 core attivo). Inoltre, l'Extreme CPUs offre un moltiplicatore sbloccato per un overclocking più semplice.

L'Ivy Bridge è un miglioramento tramite ridimensionamento dell'architettura Sandy Bridge con migliorie sia sulle prestazioni GPU che CPU. Le CPUs sono realizzate in 22nm (contro i 32nm delle CPUs Sandy Bridge) e sono le prime ad introdurre transistors 3D per l'incremento dell'efficienza energetica se si confrontano i processori Sandy Bridge con clock simile. Altre nuove features sono il PCI Express 3.0 ed il supporto DDR3(L)-1600.

Le prestazioni del Core i7-3940XM dovrebbero essere leggermente superiori ad un processore Sandy Bridge con clock simile grazie ai piccoli miglioramenti dell'architettura. A causa della velocità clock superiore, il precedente campione Core i7-3920XM dovrebbe essere superato di circa il 3%.

La Intel HD Graphics 4000 integrata offre 16 Execution Units (EUs) con un clock da 650 MHz fino a 1350 MHz con il Turbo Boost, rendendola la variante più veloce.

Le CPUs XM hanno un TDP di 55 Watts incluse scheda grafica e controller di memoria e di conseguenza sono di 10 Watt superiori rispetto agli altri modelli quad-core. Di conseguenza, la CPU è adatta a portatili a partire da 17 pollici.
