Difference Between Traditional CPU and Soc: CPU stands for “Central Processing Unit”. It is actually an Electronic Circuit. Traditionally, the term “CPU” refers to a processor, more specifically to its processing unit and control unit (CU). In general, you can find it in all computer devices and also on smartphone, tablets etc.
CPU is responsible for carrying out the instructions of a computer program by performing the basic arithmetical, logical, and I/O operations of the system. However, to perform these tasks efficiently, the CPU requires help from other components, which includes Random Access Memory (RAM), the graphics processor, and more.
A central processing unit steps expensive as individual equipment desires power for correct functioning. With enlarged power usage, the total setup encompasses a tendency to overheat. to take care of the temperature of the total unit users square measure compelled to speculate heftily incorrect cooling solutions. The most common architecture used for smartphone processors today is called ARM.
However, the CPU is highly customizable as the user can easily swap-out and change components at any time.
On the other hand, SoC stands for “System on a Chip”. It is an integrated circuit that combines all the primary components of a computer into a single chip. For example, CPU, memory controller, graphics card, co-processors, connectivity components and other components all rolled into a single chip.
So, SoC is much much more than a CPU. A CPU is usually referred to as a “microprocessor”. A SoC is sometimes can be considered as a “microcontroller”.
The cost of manufacturing and employing a SoC is very low because of the inclusion of all the parts on one chip. However, the SoCs can’t be customized by a user. If any parts of those SoCs gets broken, it can’t be repaired or swapped out. In such a situation, the user would devise with a brand new one.
