Essential computer specs

There’s a lot of information you can learn about what's inside your computer, but in most cases, you’ll be interested in one of the key specs listed here.

If you already know which spec you’re interested in and want to quickly learn how to check its details, hop down below.

This article contains:

    CPU

    The CPU (central processing unit) is your computer’s brain. Many programs need a CPU with a minimum level of processing power, so you’ll want to know exactly what your computer can handle. An overworked CPU can easily overheat, so it’s good to monitor your CPU temperature, especially when putting it under heavy stress.

    GPU

    Your GPU (or graphics processing unit) handles everything you see on your screen. Knowing your GPU specs is especially important for gaming and other graphics-intensive tasks like video editing. Just like your CPU, your GPU can also overheat if you give it more than it can handle.

    RAM

    Your computer uses RAM (random access memory) to juggle all its active tasks at any given moment. The more RAM you have, the more your computer can handle — the more tasks it can process — at once.

    Motherboard

    Your CPU, GPU, and RAM all connect to the motherboard, which lets them communicate with one another. Since it’s a piece of hardware, the motherboard has certain physical limits — for example, if your motherboard has only two RAM slots, you won’t be able to install more than two RAM modules if you’re upgrading your RAM.

    Hard drive space

    Whenever you’re installing a new program, it’ll tell you how much space in the hard drive it needs. If you don’t have enough, you won’t be able to install it. The same goes for downloading or creating new files.

    Why should I check my PC specs?

    Understanding the hardware inside your PC can help you with a number of tasks and in a variety of situations. Here are a few examples of when it would be good to know how to check your RAM, your CPU, and your other computer specs:

    • When you’re selling your PC: When selling your computer, list all its specs together. This will give potential buyers the info they need to make an informed decision, and it will also help you figure out how much you should charge.

    • When you want to buy a new PC: Looking at your current specs can help you figure out what you need in a new computer. Learning where your current machine falls short will help you determine how powerful your new computer should be. If you’re building your own machine, you can compare CPU specs and look at different GPU benchmarks to decide what you need.

    • When you need support: Got a hardware or other performance issue? When contacting tech support, be ready to give them the relevant specs for your issue. To give you the best advice, they’ll need to know what you’re working with.

    • When you’re updating your drivers: You’ll need to know the exact model number of your graphics or sound card when you update your graphics drivers or update your audio drivers.

    • When you want to try a new game or app: Got an older PC or laptop and want to play the latest game — or even a classic like GTA 5 or Ark: Survival Evolved? First, make sure your computer meets the game’s minimum requirements. If not, you won’t be able to install it.

    • If you’re overclocking your CPU or GPU: Overclocking your CPU or GPU means tuning it so that it runs faster than it otherwise would with its default settings. Before you start, check your specs and stress-test your CPU or GPU so that you know your starting point. CPU and GPU overclocking can be a bit risky, so you’ll want to gather as much info as you can before you start. 

    No matter what you’re doing, keep reading our guide for Windows 10, 8, and 7 to learn how to check out all your PC’s hardware specifications, such as installed memory, system summaries, and details about your operating system.
