Intel Core i7-640M

Intel 640M

L'Intel Core i7-640M è una CPU dual core di fascia alta per portatili ed ha un clock (grazie al Turbo Mode) da 2.8 a 3.46 GHz. Ogni core si basa sulla micro architettura Nehalem (Westemere). L'Hyperthreading consenta alla CPU Dual Core di gestire 4 threads contemporaneamente (per un miglior utilizzo della pipeline). Di conseguenza, la i7-640M si collega alle altre CPUs dual core i5 ed i3 e non alle CPUs quad-core i7.

Una feature del nuovo Core i7-640M è la scheda grafica integrata chiamata Intel HD Graphics (GMA HD) ed il controller di memoria. Entrambi sono su una die separata che è sempre realizzata in 45nm mentre la die della CPU è realizzata con il nuovo processo a 32nm.

I cores della CPU 32nm della generazione Westmere possono anche processare alcune nuove istruzioni per accelerare la codifica AES. Rispetto alla versione i5 più lenta senza features AES, il punteggio del 3DMark Vantage Communication ha mostrato un significativo incremento per le CPUs con AES abilitato.

La scheda grafica integrata Intel Graphics Media Accelerator HD (GMA HD) ha un clock da 500-733 MHz ed ha prestazioni nettamente superiori rispetto alla vecchia GMA 4500MHD. Una GeForce 9400M (ION) dovrebbe essere comunque più veloce (specialmente in quanto le schede Nvidia ed ATI hanno un miglior supporto driver rispetto ad Intel sino ad oggi).

Il consumo di energia di 35 Watt TDP (max.) comprende tutto il pacchetto e di conseguenza è sicuramente meglio rispetto ai 35 Watt TDP della serie Core 2 Duo T- (solo CPU).

Il Core i7-640M non deve essere confuso con il Core i7-620UM (1.2-2.26 GHz, 18 W) che ha un core simile ma è a basso voltaggio.
