Features

1.Uses hyperthreading technology
Intel Core i7-8700T
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 i7-8700T
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 i7-8700T
Intel i7-3940XM Extreme Edition

AES is used to speed up encryption and decryption.

4.Supports hardware-assisted virtualization
