CPU Processor | The Best Hardware Types For Computing

A Central Processor, or CPU Processor, is arguably the most important component of any computing device. It handles basic instructions and allocates the more complicated tasks to other specific chips to get them to do what they do best. It’s the core of your PC, smartphone, or tablet. and it’s what makes the whole device run as it should.

The CPU itself is a core component of what makes a computer a computer, but it isn’t the computer itself — it’s just the brains of the operation. It’s a small computer chip that sits atop the main circuit board (motherboard) of a computer, whether that’s a desktop PC, laptop, or tablet.

CPU Processor

It’s distinctly separate from the memory, which is where information is stored, and the graphics card or graphics chip, which handles all rendering of video and 3D graphics to your monitor or screen. A CPU Processor is the logic circuitry that responds to and processes the basic instructions that drive a computer.

What is a CPU Processor?

The CPU Processor is seen as the main and most crucial integrated circuitry (ICchip in a computer. For one thing, as it is responsible for interpreting most of the computer commands. CPUs will perform most basic arithmetic, logic, and I/O operations, as well as allocate commands for other chips and components running on a computer.

The term processor is used interchangeably with the term central processing unit (CPU), although strictly speaking, the CPU is not the only processor in a computer. The GPU (graphics processing unit) is the most notable example. But, the hard drive and other devices within a computer also perform some processing independently.

How important is the CPU?

Although the CPU isn’t as important for overall system performance as it once was, it still plays a major part in making a device run quickly. Since it is solely responsible for executing commands within programs, the faster your CPU is, the faster many applications will run.

That said, a fast CPU isn’t everything. A processor, no matter how powerful, can’t easily render the latest 3D games, nor can it store information. That’s where other components, like graphics cards and memory, come into play.

In short, the CPU isn’t everything, but it is important. In general, a faster CPU will mean that your system or device will run faster. At the very least it won’t be a bottleneck in its own right. Multiple cores and threads can help you do more things at once.

The Basic Elements of a CPU Processor

In the context of modern devices, a desktop or laptop will have a dedicated CPU that performs a number of processing functions for the system.

Mobile devices and some tablets instead utilize a “System on Chip” (SoC) which is a chip that contains its  CPU alongside other components. Intel and AMD both offer CPUs with graphics chips and memory stored on them too, meaning they can do more than just standard CPU functions.

One of the most common advancements of CPU technology is in making those transistors smaller and smaller. That’s resulted in the improvement to CPU speed over the decades, often referred to as Moore’s Law. The two main competitors in the processor market are Intel and AMD.

The basic elements of a CPU processor include:

  • The arithmetic logic unit (ALU), which carries out arithmetic and logic operations on the operands in instructions.
  • The Floating Point Unit (FPU), also known as a math coprocessor or numeric coprocessor, a specialized coprocessor that manipulates numbers more quickly than the basic microprocessor circuitry can.
  • Registers, which hold instructions and other data. Registers supply operands to the ALU and store the results of operations.
  • L1 and L2cache memory. Their inclusion in the CPU saves time compared to having to get data from random access memory (RAM).

The General Types of a CPU Processor 

Most processors today are multi-core, which means that the IC contains two or more processors for enhanced performance, reduced power consumption and more efficient simultaneous processing of multiple tasks (see: parallel processing).

Multi-core set-ups are similar to having multiple, separate processors installed on the same computer. Most computers may have up to two-four cores; however, this number can increase up to 12 cores, for example.

If a CPU can only process a single set of instructions at a go, then it is a single-core processor. And if a CPU can process two sets of instructions at a time it’s a dual-core processor. Whereby, four sets are a quad-core processor.

The more cores, the more instructions at a time a computer can handle. Some processors use multi-threading, which uses virtualized processor cores. Virtualized processor cores are called vCPUs. These are not as powerful as physical cores but can be used to improve performance in virtual machines (VMs).

However, adding unnecessary vCPUs can hurt consolidation ratios, so there should be about four-six vCPUs per physical core.

What are the CPU Components?

The main components of a CPU are the ALU, registers and control unit. Not forgetting, the processor in a personal computer or embedded in small devices is often called a microprocessor. This means that the processor elements are in a single IC chip. Some computers will operate using a multi-core processor—a chip containing more than one CPU.

A CPU is typically a small device with pins on it facing down in a motherboard. CPUs can also be attached to a motherboard with a heat sink and a fan to dissipate heat. The four primary functions of a processor are to fetch, decode, execute and write back.
  • Fetch- is the operation that receives instructions from program memory from a systems RAM.
  • Decode- is where the instruction is converted to understand which other parts of the CPU are needed to continue the operation. This is performed by the instruction decoder
  • Execute- is where the operation is performed. Each part of the CPU that is needed is activated to carry out the instructions.

What does a CPU actually do?

At its core, a CPU takes instructions from a program or application and performs a calculation. This process can be broken down into three key stages: Fetch, decode, and execute. A CPU fetches the instruction from a system’s RAM. Then it decodes what the instruction actually is before it is executed by the relevant parts of the CPU.

The executed instruction, or calculation, can involve basic arithmetic, comparing certain numbers together, or moving them around in memory. It’s what facilitates everything from starting up Windows, to watching a YouTube video.

In modern systems, the CPU doesn’t do everything, but it still has to feed specialized hardware the numbers they need to do their job. It needs to tell the graphics card to show that explosion because you clicked on that fuel barrel, or grab the contents of your Office document from the local memory

The CPU Cores, Clocks, and Costs

Originally, processors had a single processing core. Today’s modern processors are made up of multiple cores that allow it to perform multiple instructions at once. They’re effectively several CPUs on a single chip.

Almost all CPUs sold today are at least dual-core, but at the higher end, you’ll see four (quad) core CPUs, and even six, eight and 12 core CPUs in some cases. Some processors also employ a technology called multi-threading, which creates virtual processor cores. They aren’t as powerful as physical cores, but they can help improve a CPU’s performance.

Clock speed is the “gigahertz,” (GHz) figure that you’ll see quoted on CPU product listings. It effectively denotes how many instructions a CPU can handle per second, but that’s not the whole picture when it comes to performance.

Mostly, clock speed comes into play when comparing CPUs from the same product family or generation. When all else is the same, a faster clock speed means a faster processor, but a 3GHz processor from 2010 isn’t going to be as fast as a 2GHz processor from 2018.

AMD vs Intel: Who Makes the Best CPU Processor?

Often, whether to go for AMD vs Intel CPU Processor is a dilemmatic question many computing geeks always seek answers for. And at the heart of your pursuit for a new or upgraded PC beats an important decision. Of course, which CPU Processor should I consider using between AMD vs Intel?

On the contrary, like MacOS vs Windows or rather Star Wars vs Star Trek, the AMD vs. Intel rivalry is one of the greatest debates for PC enthusiasts. It used to be that Intel processors and platforms were considered more secure than AMD solutions.
