Features

1.Uses hyperthreading technology
Intel Core i5-6402P
Intel Core i7-7700K

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 i5-6402P
Intel Core i7-7700K

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 i5-6402P
Intel Core i7-7700K

AES is used to speed up encryption and decryption.

4.SSE version

4.2

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.

Best

Intel Core i7-9800X
