Multiple cores in smartphones explained

In this post we will discuss about multipe cores, which are found in our smartphone's Processor.

Firstly, The CPUs in a processor had a single core. That means the physical CPU had a single central processing unit.

To increase the performance, manufacturers planned to add additional cores on CPUs. A Dual-Core CPU has 2 central processing units, so it appears to the operating system as two CPUs. A CPU with two cores, For example, It could run two different processes at the same time.

This process speeds up your system, because your computer can do multiple things at once.

Unlike hyper-threading, there are no tricks here — a dual-core CPU literally has two central processing units on the CPUs chip. A quad-core CPU has 4 central processing units, an Octa-core CPU has 8 central processing units, and so on.

This also helps dramatically to improve the performance while keeping the physical CPU unit small so it fits in a single socket. There are only needs to be a single CPU socket with a single CPU unit inserted into it—not four different CPU sockets with four different CPUs, each are needed with their own power, cooling, and other hardware. There is less latency because the cores can communicate more quickly, as they’re all on the same chip.

Windows’ Task Manager shows this fairly well. For example: That this system has one actual CPU (socket) and four cores. Hyperthreading makes each core look like 2 CPUs to the operating systemS, so it shows 8 logical processors.
