      Features

      1.Uses hyperthreading technology
      Intel Core i7-3940XM
      Intel Core i7-7820HK
      Intel i7-3940XM Extreme Edition

      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 i7-7820HK
      Intel i7-3940XM Extreme Edition

      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 i7-7820HK
      Intel i7-3940XM Extreme Edition
