Intel Core i5 four generation and i5 three generations of difference one: Core i5 4570 pin
If you want to buy a notebook, you can check it out.
At first glance, I was shocked. I haven't looked at it for a long time. The intelcpu came out with so many models. It was a bit confusing. Fortunately, I had a network and checked it and sorted it out.
The current market's CPUs include T series, P series, E Series, I3, I5, and i7.
The T series is Intel dual-core and mainly used in laptops. Including Pen
Hyper-Threading
Hyper-threading means that each processor core can handle two threads rather than one, with better performance when running Windows systems and some compatible software. Generally speaking, the i5 processor does not have hyper-threading capability, while I7 is basically supported, and has better results when taking photos and video editing operations, which users need to consider.
Clock frequency
The clock frequency, which is the
four cores eight threads, Intel Core i5 4570 is a four cores four threads and so on. for a CPU, the number of threads is always greater than or equal to the number of cores. One core

Judge the basis:
1. CPUs with the same core ID are the same core hyper-threading.
2. CPUs with the same physical ID are the same CPU-encapsulated threads or cores.
English version:
1.Physical ID and core ID are not necessarily consecutive but they unique. Any CPUs with the same core ID are hyperthreads in the same core.
2.Any CPU with the same physical ID are threads or cores in the same socket.
