A central processing unit, or CPU, is the brain of your computer, handling both tasks that require high performance XD and lower-level functions like booting up your system. A computer without a working CPU can’t run any programs, rendering it useless. When you need to upgrade your CPU, you have two options: You can either build one yourself or purchase one from an external vendor. The former option will get you the best performance, but it’s also very complicated and requires plenty of time and patience to complete.


How Does a CPU Work?

A CPU is a piece of silicon that’s etched with millions of transistors, much like other semiconductors. The big difference is that each transistor in a CPU carries out a very simple function and they’re all controlled by a computer program written into your operating system. Simply put, your computer sends an electrical current through billions of transistors in order to carry out what you asked it to do. It does that by turning on and off these tiny switches at breakneck speeds. To illustrate how fast these switches are turning on and off, let’s examine exactly how much time it takes for one cycle.


Different Types of Intel Processors

There are a number of different variations of Intel processors out there that can be easily confused. Below is a list of some commonly used abbreviations and what they stand for: G3 – A single-core processor based on a Pentium 4 design. They operate at speeds between 1.1 and 2.0 GHz and were released between 2004 and 2007. G4 – A single-core processor based on a Pentium 4 design, operating at speeds of between 1.1 and 2 GHz, with Hyper-Threading support enabled.


Graphics Processing Units (GPU)

GPUs are a type of chip designed specifically for graphics processing—namely, rendering images, animations and video. The complex work they do is referred to as computing. The GPU helps with everything from artificial intelligence (AI) applications to virtual reality (VR) games. Modern GPUs feature thousands of tiny processors built into an integrated circuit; these processors need ample cooling, which can be provided by things like fans or water-cooling systems. No matter what GPU you have installed in your system, it’ll require some amount of power so plan accordingly and build a system that’s efficient enough for gaming but also flexible enough if you decide to upgrade in the future.


Internet of Things (IoT) Devices

Computers, phones, and other devices that are connected to networks of computers called servers. Servers collect and store data that may be useful or needed in the future. As a result, these devices can learn more about what you like and where you go during your day-to-day life. This is particularly true of IoT devices like smart thermostats (think Nest) or smartphones (think Apple Watch). Internet servers collect information from IoT devices when they’re on Wi-Fi—your Android phone is always on Wi-Fi, even when it’s not being used—and then use machine learning techniques to understand your behavior patterns and habits.


What Is an Operating System?

An operating system (OS) is software that manages a computer’s various functions. Operating systems are considered one of the most crucial parts of a computer, because they allow for high-level functions like multitasking, storing files and running programs. There are many different kinds of operating systems available on computers today. Some examples include: Windows 7, Mac OS X and Linux.


The Future of Processor Technology

One of the biggest trends in processor technology is increasing parallelism. That’s because, over time, we’re finding more ways for computers to use multiple processors at once. Look no further than your own smartphone: It’s one of several devices today that have anywhere from two to four processing cores (which contain their own set of processing units), and it only made sense that traditional computer chips would eventually follow suit. As it turns out, not all chip manufacturers are capable of churning out high-performance chips with multiple cores on a single die—but even if they could, they wouldn’t necessarily be able to make them as energy efficient as smaller processors with fewer cores.
