Intel Core i7-4940MX

Intel 4940MX

De Intel Core i7-4940MX is een high-end quad-core processor voor laptops en de opvolger van de i7-4930MX. Hij is gebaseerd op de Haswell-architectuur en werd gelanceerd in het eerste kwartaal van 2014. Dankzij Hyperthreading kunnen de vier cores tegelijk tot en met acht threads in parallel aan, wat resulteert in efficiënter gebruik van de CPU. Elke core biedt een basiskloksnelheid van 3.1 GHz maar kan met Turbo Boost dynamisch overklokken tot 3.8 GHz (voor 4 actieve core), 3.9 GHz (voor 2 actieve cores) en 4.0 GHz (voor 1 actieve core). De 2C/4C Turbo kloksnelheden zijn nog niet bevestigd. Bovendien beschikken de Extreme CPU's over een ontgrendelde multiplier die eenvoudig overklokken toelaat.

Architectuur

Haswell is de opvolger van de Ivy Bridge-architectuur met verbeteringen aan zowel GPU als CPU performance. De CPU's zijn gefabriceerd in 22nm en bieden een geoptimaliseerde aftakkingsvoorspelling en bijkomende execution ports, wat de performance in verhouding tot de kloksnelheid met zo'n 5 - 10 procent verbetert. Bovendien zouden nieuwe functionaliteiten zoals AVX2 en FMA de prestaties voor toekomstige applicaties moeten verhogen.

Prestaties

Vergeleken met de Core i7-4930MX, is de 4940MX precies 100 MHz sneller geklokt en daarom net iets sneller. Over het algemeen zijn de prestaties vergelijkbaar met die van de Desktop Core i7-4770K. Zelfs extreem veeleisende software of multitasking wordt met gemak afgehandeld.

Grafisch

De geïntegreerde Intel HD Graphics 4600 biedt 20 Execution Units (EU's) geklokt aan 400 MHz tot en met 1350 MHz met Turbo Boost, wat de chip ongeveer 30% sneller maakt dan de HD 4000. Dit is iets trager dan de AMD Radeon HD 8650G, maar vergelijkbaar met een dedicated GeForce GT 720M.

Stroomverbruik

De i7-4940MX is afgestemd op een TDP van 57W, inclusief grafische kaart, geheugencontroller en VRM's. Daarom is de CPU enkel geschikt voor laptops van het 17 inch-formaat of groter.
