Intel Core i7-2820QM

Intel 2820QM

L'Intel Core i7-2820QM è un veloce processore di fascia alta quad core per portatili. Al momento del suo annuncio (Gen. 2011) era il processore da 45 Watt più veloce. Si basa sulla architettura Sandy Bridge ed offre l'Hyperthreading per la gestione simultanea di 8 threads (per un miglior utilizzo della pipeline). Rispetto ai precedenti Clarksdale quad-cores, l'i7-2820QM ora è realizzato in 32nm ed offre una scheda grafica integrata e funzioni AES. Rispetto alla 2720QM con un clock inferiore, la 2820QM offre più level 3 cache (8 vs. 6MB).

Sandy Bridge è il successore evolutivo della architettura Arrandale. I principali miglioramenti sono le nuove istruzioni 265Bit AVX, il Turbo Boost migliorato e l'integrazione della scheda grafica nel core CPU da 32nm. Inoltre, il controller di memoria integrato è stato migliorato ed ora supporta fino ad 8 GB di DDR3-1333.

L'i7-2820QM offre una scheda grafica integrata (Intel HD Graphics 3000) che si è mostrata nettamente più veloce rispetto alle vecchie Intel HD Graphics delle CPUs Arrandale ed al livello delle schede grafiche dedicate di fascia bassa come la GeForce 310M. La HD Graphics 3000 supporta anche il Turbo Boost ed ha un clock tra 650 MHz e 1300 MHz. Poiché la scheda grafica condivide la veloce level cache, il processore sarà leggermente più lento con la GPU attiva.

Le prestazioni del Core i7-2820QM sono notevolmente migliori (es. versioni Cinebench) rispetto alla precedente generazione di Core i7-940XM quad core. Pertanto, le prestazioni dovrebbero essere sufficienti per i moderni giochi 3D e le applicazioni impegnative. Grazie al veloce Turbo Boost 2.0 anche le applicazioni single threaded girano molto velocemente. I risultati dettagliati del benchmark del 2820QM possono essere reperiti nella sezione inferiore di questa pagina.

Il valore di TDP relativamente elevato del 2820QM da 45 Watt permette l'utilizzo del quad core solo nei portatili a partire dai 15". Tuttavia, rispetto alla precedente generazione di quad-cores, tuttavia, è presente un miglioramento del TDP, grazie alla GPU integrata.
