    General info

    1.Supports 64-bit
    AMD Phenom II X4 955
    Intel Core i7-3940XM

    A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit applications.

    2.semiconductor size

    45nm

    22nm

    A smaller size indicates that the process to create the chip is newer.

    Features

    1.Uses hyperthreading technology
    AMD Phenom II X4 955
    Intel Core i7-3940XM

    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
    AMD Phenom II X4 955
    Intel Core i7-3940XM

    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
    AMD Phenom II X4 955
    Intel Core i7-3940XM

    AES is used to speed up encryption and decryption.

    4.SSE version

    4

    4.2

    SSE is used to speed up multimedia tasks such as editing an image or adjusting audio volume. Each new version contains new instructions and improvements.
