Intel Core i7-3940XM

Intel 3940XM

O Intel Core i7-3940XM é o processador quad-core mais veloz para portáteis (no momento da introdução em Setembro de 2012) um sucessor do i7-3920XM. Graças ao Hyperthreading, os quatro núcleos podem suportar até oito threads em paralelo fazendo uma melhor utilização do CPU. Cada núcleo oferece uma velocidade base de 3,0 GHz, mas pode aumentar a freqüência dinamicamente com Turbo Boost, até 3,7 GHz (para 4 núcleos ativos), 3,8 GHz (para 2 núcleos ativos) e 3,9 GHz (para 1 núcleo ativo). Além disso, os CPUs Extreme oferecem um multiplicador desbloqueado para a fácil aceleração (overclocking).

Ivy Bridge é uma matriz aprimorada e reduzida da arquitetura Sandy Bridge com melhorias no desempenho do GPU e CPU. Os CPUs são produzidos em 22nm (contra 32nm dos CPUs Sandy Bridge) e são os primeiros em introduzir transistores 3D para uma maior eficiência energética quando comparado com processadores Sandy Bridge com frequências similares. Outros novos recursos são o PCI Express 3.0 integrado e suporte para DDR3(L)-1600.

O desempenho do Core i7-3940XM deve ser ligeiramente superior que o de um processador Sandy Bridge com frequência similar graças a ligeiras alterações estruturais. Devido à maior frequência, o ex-campeão, Core i7-3920XM, deve ser superado por cerca de 3%.

O Intel HD Graphics 4000 integrado, oferece 16 Unidades de Execução (EUs) com frequência de 650 MHz até 1350 MHz com Turbo Boost, tornando-o a variante mais rápida.

Os CPUs XM estão classificados em um TDP de 55 Watts incluindo a placa de vídeo e controlador de memória e, portanto, 10 Watts mais alto que os outros modelos quad-core.  Portanto, o CPU é bem adequado para portáteis de 17 polegadas ou maiores.
