Intel Core i7-3940XM

Intel 3940XM

De Intel Core i7-3940XM is de snelste quad-core processor voor laptops (in September 2012) en de opvolger van de i7-3920XM. Dankzij Hyperthreading kunnen de vier cores tot acht threads parallel draaien wat tot beter gebruik van de CPU leidt. Elke core heeft een basissnelheid van 3.0 GHz maar kan met Turbo Boost dynamisch overgeklokt worden naar 3.7 GHz (bij 4 actieve cores), 3.8 GHz (bij 2 actieve cores) of 3.9 GHz (bij 1 actieve core). Verder hebben de Extreme CPU's ook een open multiplicator zodat je makkelijk over kunt klokken.

Ivy Bridge is een verbeterde versie van de Sandy Bridge architectuur met betere prestaties van zowel de GPU als de CPU. De CPU's worden gemaakt op 22nm (vergeleken met de 32nm van de Sandy Bridge CPU's) en zijn de eerste die 3D transistors gebruiken voor een efficiënter verbruik vergeleken met de Sandy Bridge processors. Andere nieuwe features zijn de geïntegreerde PCI Express 3.0 en DDR3(L)-1600 ondersteuning.

De prestaties van de Core i7-3940XM zouden iets beter moeten zijn dan die van een vergelijkbaar geklokte Sandy Bridge processor door de kleine architectonische  verbeteringen. Vanwege de hogere kloksnelheid zal de nieuwe processor het ongeveer 3% beter doen dan het vorige topmodel, de Core i7-3920XM.

De geïntegreerde Intel HD Graphics 4000 heeft 16 Execution Units (EU's) met kloksnelheden van 650 MHz tot 1350 MHz met Turbo Boost wat het de snelste variant maakt.

De XM CPU's hebben allen een TDP van 55 watt inclusief grafische kaart en geheugencontroller en daardoor verbruiken ze 10 watt meer dan andere quad-core modellen. Deze CPU is geschikt voor laptops van 17-inches of meer.
