When we are about to buy a new electronic device one of the components to check with more attention is the processor, that's what it is
When we look at the technical characteristics, before buying a computer, a smartphone or any electronic object, one of the aspects that we look at with more care is the processor. Often we identify this component with names but without really knowing what we are talking about.
When we hear the word processor we must know that it is a technology that has more than 50 years of development. It was theorized and applied, in fact, during the years of World War II. Despite all this time the processor remains a fundamental component for most devices. Within a computer, the CPU performs the delicate task of the system's computational center. Basically, the incoming data from the input peripherals and other components, such as GPU, RAM and so on, are processed according to the instructions of the various algorithms that make up a software, and then returned to the output peripherals.
How many cores?
With the growth of technological development, the process inside the CPU has been increasingly complicated, and this has led to the realization of more advanced processors. In order to double or quadruple the number of operations to be performed at the same time, the microcircuitry giants, Intel or AMD to name a few, increased the number of cores (the components that physically process data) inside the processors. Multi-core processors appeared around the 2000s and represented a real revolution for technological devices. Significantly increasing their computing power.
SoC, CPU and multiprocessor
The term multi-core refers to dual-core, quad-core, exa-core, octa-core and so on, and in practice refers not only to computer CPUs but also to SoC (System on a Chip) of smartphones and tablets. These are computing units that share the same silicon plate. When we talk about multiprocessor systems, however, we refer to those machines that contain within them two or more CPUs linked together.
Multi-core processors offer many advantages over a single-core multiprocessor. Mainly on the performance level. With a multi-core, the response times of a device are much faster. This is possible because the distance separating two cores within the same processor is less than the distance that must necessarily separate two different CPUs. In addition, multi-core systems also ensure greater energy efficiency for the device's battery. This aspect makes a difference especially on smartphones and smartwatches.
