Intel Core i7-3940XM

Intel 3940XM

Intel Core i7-3940XM var vid lanseringen i september 2012 den snabbaste fyrkärniga processorn i Intels Ivy Bridge-familj och därför också den snabbaste processorn för bärbara datorer totalt sett vid lanseringen.

Med hjälp av Inteltekniken HyperThreading kan processorns fyra kärnor hantera upp till åtta trådar parallellt och hanteras som en 8-kärnig CPU av operativsystemet. Varje kärna har en bashastighet på 3,0 GHz men processorn ökar automatiskt klockfrekvensen (med funktionen Turbo Boost) upp till 3,7 GHz med 4 aktiva kärnor, 3,8 GHz med2 aktiva kärnor och 3,9 GHz med 1 aktiv kärna – 100-200 MHz högre klockfrekvenser per steg jämfört med föregångaren Core i7-3920XM.

Ivy Bridge är en optimerad version av föregångaren Sandy Bridge som även förminskats och tillverkas i 22nm istället för 32nm. Processorerna är först med 3D-transistorer ("tri-gate") och är mer effektiva än Sandy Bridge-processorer med samma klockfrekvens. Både GPU- och CPU-prestanda har förbättrats. Andra nya funktioner är stöd för PCI Express 3.0 och DDR3 (L) 1600.

Prestandan med Core i7-3940XM är bättre än en Sandy Bridge-processor med samma klockfrekvens.  På grund av de högre klockfrekvenserna är prestandan ca 3 % bättre än toppmodellen Core i7-3920XM.

Till skillnad från de andra fyrkärniga Ivy Bridge-processorerna (förutom i7-3612QM), som har en TDP på 45 Watt, har Core i7-3940XM en TDP på 55 Watt. Det gör CPU:n bäst lämpad för större bärbara datorer (från 17 tum och uppåt). Eftersom den tillhör XM-serien (Extreme Edition) är den också upplåst och kan överklockas.
