Intel Core i7-640M

Intel 640M

Core i7-640M to najwydajniejszy z dwurdzeniowych procesorów Arrandale (Core pierwszej generacji). Jego osiągi w aplikacjach jednowątkowych są lepsze od większości czterordzeniowych i7 pierwszej generacji (ze względu na wysoką częstotliwość taktowania), a w zadaniach wykorzystujących wszystkie wątki jest niewiele gorszy od najsłabszego z nich, tj. i7-720QM. Od Core i3-330M jest on wydajniejszy o około 50%, a od Pentium P6000 – dwukrotnie wydajniejszy. Jest to procesor niezbyt popularny w naszym kraju, stosowany głównie w notebookach z wyższej półki, aczkolwiek w marcu 2010 roku najtańsze modele z tym CPU kosztowały nieco ponad 4 tys. zł.
