Intel Core i7-2649M

O Intel Core i7-2649M é um processador LV (Low Voltage) energeticamente eficiente para portáteis. A freqüência base de 2,3 GHz é relativamente baixa, mas graças ao Turbo Boost 2.0, o CPU pode atingir até 3,2 GHz (um núcleo carregado, 2,9 GHz com ambos os núcleos carregados). Porém, isto depende do esfriamento e consumo de energia do portátil. Graças ao HyperThreading, o i7-2649M é capaz de agüentar 4 threads em paralelo. Comparado com o similarmente chamado Core i7-2620M, o 2649M é mais lento, mas também precisa de menos energia (25W contra 35W).

A Sandy Bridge é a sucessora evolucionária da arquitetura Arrandale. As melhorias mais notáveis são o Turbo 2.0 melhorado e a integração da placa de vídeo no núcleo do CPU de 32nm.

A Intel HD Graphics 3000 integrada com freqüência de 500 ou 1100MHz (Turbo Boost). Devido à freqüência mais baixa, comparada com a HD Graphics 3000 em processadores de 35W e 45W (normalmente com freqüência de 650), o desempenho deve ser um pouco mais baixo.

O desempenho do CPU deve ser um pouco mais alto que o de um Arrandale Core i7 LV com freqüência similar. Portanto, o desempenho deve estar um pouco acima do Core i3-390M se o Turbo pode ser usado freqüentemente.

O TDP de 25W (inclui o GPU  integrado e controlador de memória) permite o uso do CPU 2649M CPU em portáteis finos.
