![]() In a professional workstation, you’ll be doing tasks like running multiple spreadsheets, browsing the web, and performing medium duty tasks. Here are a couple options from the most recent generation: For your home computer, I would recommend the most basic pricing option with an Intel Core-i3 or an AMD Ryzen 3 (there are even more basic options like the Intel Pentium or Celeron CPUs if you are operating from a very small budget). In a system like this, heavy workloads aren’t common and you won’t need many processor cores. In a home computer, I’m referring to the computer for the house that is used to check emails, play music, or browse the web. Intel and AMD both follow the, basic, good, better, best pricing/performance model with their CPUs. ![]() I usually like to break systems down into 4 categories to decide what hardware is best for my task: Home Computer, Professional Workstation, Gaming System, and Media Workstation. So what stats should I focus on when buying a CPU? So, you can never assume that 2 identical clock speeds are going to produce the same results unless they are the same brand and model. Most modern CPUs can complete one instruction or more during a clock cycle, but there are many different processor architectures and designs. So, a processor with a 3.5GHz clock frequency, completes 3.5 billion clock cycles per second. ![]() Clock speed is the amount of pulses from the oscillator that are completed per second. A clock cycle is the amount of time between two pulses from an oscillator (a device for generating repetitive electric pulses). Pretty fast, right? Well, to really understand how fast that is, we need to understand what happens in a clock cycle. 1 hertz is how long it takes for your CPU to complete one clock cycle.ġ megahertz = 1 million cycles per secondġ gigahertz = 1 billion cycles per second More specifically, in this case, Gigahertz. There are two terms to look out for, Let’s take a look at this image again from before:Īs you’ll notice, your CPU’s frequency (speed) is measured in hertz. While processor cores can still only handle one instruction at a time, with multiple threads, a core can always have a constant stream of 8 instructions so it never has to wait for information.Įnough talk about cores and threads, It’s time to address your CPU’s clock speed. The graphics below show an example of a 4-core, 4-thread processor, and a 4-core, 8-thread processor. While each worker can only do one task at a time, when you can divy 2 tasks to each worker, instead of only being able to have 4 tasks on your processor’s plate, now you can have 8. Until multithreading became popular, processor cores would have one stream of instructions executed at a time, and when they were finished with that task they would wait for the next instruction line.īack to our analogy with the workers, a thread is equivalent to how many tasks you let each worker have on their plate at once. The threads in a processor, are the channels that send information to the cores. You’ve probably seen a second number referring to the amount of cores a processor has. They are each capable of working on different tasks, but all serve the same ultimate goal. You can think of a CPU as an office and each core is like a cubicle with a worker in it. However, the performance of a multi-core processor depends heavily on the software utilization in the programs you are using. This can tremendously increase the performance of your computer because you don't have to wait for tasks to be completed before your CPU can start the next one. The more cores your CPU has, the more instructions it can execute simultaneously. Each core in a CPU is capable of fetching, decoding, and executing its own instructions. First, we have cores.Ī CPU core is essentially a functioning processor of its own. I’ve already done a breakdown of low-level processor function before ( ), So for this article we are just going to focus on the specific areas of the CPU and how they function together. Let’s dive into some of the functions of these parts to gain a better understanding of the role they play We will look to answer any questions you may have about which factor is most important when buying a CPU. This blog post will cover 3 main topics of CPU performance, which are cores, threads, and clock speed. The computing world is full of ways to gauge processor speed, and we have plenty of factors available.
