    Features

    1.Uses hyperthreading technology
    Intel Core i7-3940XM
    Intel Core i7-7700K
    Intel Xeon E3-1240

    Many of Intel's processors use hyperthreading, which means that each core of the processor can work on two threads at once instead of most processors which work on a single thread per core. This means you can have significant performance gains in certain applications.

    2.Has dynamic frequency scaling
    Intel Core i7-3940XM
    Intel Core i7-7700K
    Intel Xeon E3-1240

    Dynamic frequency scaling is a technology that allows the processor to conserve power and reduce noise when it is under a light load.

    3.Has AES
    Intel Core i7-3940XM
    Intel Core i7-7700K
    Intel Xeon E3-1240

    AES is used to speed up encryption and decryption.

    4.Supports hardware-assisted virtualization
    Intel Core i7-3940XM
    Intel Core i7-7700K
