Intel Core i7-820QM vs Intel Core i7-920XM

Intel Core i7-820QM

► remove from comparison Intel 820QM

Der Intel Core i7 820QM ist ein High-End Prozessor für Notebooks. Er bietet 4 Kerne (Quad Core CPU) welche, je nach Auslastung und Kühlung, mit 1.73 - 3.06 GHz getaktet wird (Turbo Modus). Dank Hyperthreading können bis zu 8 Threads gleichzeitig bearbeitet werden (zur besseren Auslastung der Prozessor-Pipeline).

Der 820QM hat einen integrierten Speichercontroller, welcher DDR3 1066 und 1333 Speicher direkt ansprechen kann. 

Der Stromverbrauch ist mit 45 Watt TDP (Maximum) im Bereich der alten Core 2 Quad Modelle, jedoch dank eingebautem Speichercontroller nicht höher. Durch den Turbo Modus wird der TDP jedoch eher ausgenutzt. Daher eignet sich der Core i7-820QM nur für große Laptops mit ausreichendem Kühlsystem.

Intel Core i7-920XM

► remove from comparison Intel 920XM

Der Intel Core i7 920XM Extreme Edition ist der stärkste Notebookprozessor in 2009. Er bietet 4 Kerne (Quad Core CPU) welche, je nach Auslastung und Kühlung, mit 2.0 - 3.2 GHz getaktet werden (Turbo Modus). Dank Hyperthreading können bis zu 8 Threads gleichzeitig bearbeitet werden (zur besseren Auslastung der Prozessor-Pipeline).

Der 920XM hat einen integrierten Speichercontroller, welcher DDR3 1066 und 1333 Speicher direkt ansprechen kann. 

Der Stromverbrauch ist mit 55 Watt TDP (Maximum) sehr hoch (jedoch inkl. eingebautem Speichercontroller). Daher eignet sich der Core i7-920XM nur für große Laptops mit ausreichendem Kühlsystem.

Die CPU gehört zur Extreme Serie von Intel CPUs und lässt sich daher dank frei wählbarem Multiplikator sehr einfach übertakten. Mit einem Anfangspreis von $1054 (bei Abnahme von 1000 Stück) ist der Prozessor jedoch sehr teuer.
