Intel Core i7-640LM

El Intel Core i7-640LM es una rapida CPU de gama media y bajo voltaje de doble nucleo para portatiles con una velocidad de reloj (gracias al modo Turbo) de 2.16 a 2.93 GHz. Cada nucleo está basado en la microarquitectura Nehalem (Westemere). La tecnologia Hyperthreading permite a la CPU de doble nucleo manejar 4 hilos de forma simultanea (para un mejor uso del pipeline). Comparado con el Core i7-620M, el 640LM es más lento pero más eficiente.

Una caracteristica del nuevo Core i7-640LM es la tarjeta gráfica integrada (llamada HD Graphics) y el controlador de memoria. Estan situados en un 'die' separado que está aún fabricado en 45 nm mientras que la CPU está ya fabricada en el nuevo proceso de 32 nm.

Debido al controlador de memoria integrado, el Hyperthreading y el Turbo Boost, el Core i5-640LM es más rapido que los Core 2 Duo a velocidad similar en todoas las aplicaciones y pruebas que conocemos. El rendimiento debería estar en el nivel del Core i5-430M. Hay que tener en cuenta que algunos diseños pueden no presentar Turbo Boost. Por tanto, la CPU puede ser más lenta que la 430M.

Los nucleos de 32nm de la generación Westmere pueden procesar algunas instrucciones para acelerar encriptados AES. Aplicaciones modernas que soporten codificación AES pueden mejorar significativamente usando las nuevas instrucciones (p.e. el test Communication Suite en PCMark Vantage mejora un 70% su velocidad usando AES en el Core i520).

La tarjeta gráfica Graphics Media Accelerator HD de Intel (GMA HD) funciona a una velocidad entre 266566 MHz (Turbo Boost) y por tanto la velocidad base difiere claramente de las versiones de bajo voltaje. El rendimiento debería ser mejor que el de la vieja GMA 4500 MHD.

El consumo de corriente de 25 vatios de TDP (maximo) es para el paquete completo y por tanto es claramente mejor que el TDP de 25 vatios de la gama P de las CPUs Core 2 Duo (en los que el TDP se correspondia solo a la CPU).
