Find your computer's specs in Windows, Mac, or Linux

Your computer's specifications tell you what hardware is inside—the processor speed, amount of memory, storage capacity, and graphics card. You can find this information in seconds without opening the machine or installing anything. The method depends on whether you use Windows, Mac, or Linux, but all three show the same core details in a built-in system tool.

Knowing your specs matters when you're buying software, troubleshooting a slow computer, or checking whether a game or program will run. You may also need them for warranty claims, selling the machine, or talking to technical support.

Key Takeaways

  • Windows users can open System Information by typing "system information" into the search box, or right-click "This PC" and select Properties.
  • Mac users can click the Apple menu, select "About This Mac," and see the processor, memory, and storage all on one screen.
  • Linux users can open a terminal and type uname -a or lsb_release -a to see system details, or use the graphical Settings app.
  • Your processor speed, RAM amount, storage type, and graphics card are the four specs you'll need most often.
  • Screenshots of your specs are useful to save if you need to reference them later or share them with technical support.

How to check specs on Windows

The fastest way is to use the search box. Click the Windows search icon (magnifying glass) in the taskbar, type "system information," and press Enter. A window opens showing your processor name and speed, total RAM, Windows version, and system type (32-bit or 64-bit).

If you want a quicker overview without opening System Information, right-click "This PC" or "My Computer" on your desktop or in File Explorer, select Properties, and you'll see the processor, RAM, and Windows version on one screen. For storage details, open File Explorer, right-click the C: drive (or whichever drive is your main one), and select Properties to see how much space is used and available.

To see your graphics card, type "device manager" into the search box, open it, and expand the "Display adapters" section. The name listed there is your GPU. If you need more detailed information—like how much memory your graphics card has—right-click the graphics card name and select Properties.

How to check specs on Mac

Click the Apple menu in the top-left corner and select "About This Mac." A single window shows your processor (called "Chip" on newer Macs), the amount of memory (RAM), storage capacity, and macOS version. This is the most complete overview you'll get in one place.

If you want to know more about your storage—how much is used, how much is free, and what's taking up space—click the "Storage" tab in the same window. For graphics card details on Intel-based Macs, click "System Report" in the About This Mac window, then select "Graphics/Displays" from the left sidebar. On Apple Silicon Macs (M1, M2, M3), the graphics are built into the chip and the About This Mac window tells you how many GPU cores it has.

How to check specs on Linux

If you're comfortable with the terminal, open it and type uname -a to see your kernel version, processor architecture, and system type. Type cat /proc/cpuinfo to see detailed processor information, or free -h to see how much RAM you have and how much is in use.

For storage, type df -h to see all mounted drives and how much space each has. To see your graphics card on Linux, type lspci | grep -i vga or lspci | grep -i 3d.

If you prefer not to use the terminal, most Linux desktop environments have a Settings or System Settings app. Open it and look for a section called "About," "System," or "Details"—the exact name varies by distribution (Ubuntu, Fedora, Linux Mint, etc.), but the information is always there.

Understanding the specs you see

Processor (CPU) is the brain of your computer. The name tells you the brand (Intel, AMD, Apple) and model. The speed, measured in gigahertz (GHz), tells you how fast it runs—higher is faster, but newer processors are more efficient than older ones at the same speed. The number of cores (like "quad-core" or "8-core") tells you how many tasks it can handle at once.

Memory (RAM) is measured in gigabytes (GB). This is temporary working space your computer uses while programs are open. More RAM means you can run more programs at once without slowdown. Typical amounts are 8 GB, 16 GB, or 32 GB for everyday use.

Storage is your hard drive or solid-state drive (SSD), measured in gigabytes or terabytes (TB). This is where your files, programs, and operating system live permanently. A 256 GB drive is common for a laptop; a 1 TB or 2 TB drive is common for a desktop.

Graphics card (GPU) handles images and video. If you see "Intel Iris" or "AMD Radeon," that's built into your processor. If you see "NVIDIA GeForce" or "AMD Radeon RX," that's a separate card, which is faster for gaming and video work. Integrated graphics are fine for everyday use.

When you need your specs and what to do with them

Before buying software or a game, check the system requirements on the product page and compare them to your specs. If the game requires an NVIDIA GeForce RTX 3060 and you have Intel Iris graphics, it won't run well. If a program needs 16 GB of RAM and you have 8 GB, it will be slow.

If your computer is running slowly, knowing your specs helps you understand why. If you have only 4 GB of RAM and you're running ten browser tabs, a video editor, and Spotify at once, that's the problem—not a virus. If your processor is from 2012 and a new program requires a 2018 processor, the software won't work.

When you contact technical support or post on a forum for help, include your specs. A support person can't troubleshoot without knowing what hardware you're working with. Take a screenshot of your System Information (Windows), About This Mac (Mac), or terminal output (Linux) and save it so you have it ready.

Frequently Asked Questions

What's the difference between RAM and storage?

RAM is temporary memory your computer uses while programs are running—it clears when you shut down. Storage is permanent space where your files and programs live. You need enough of both: RAM for smooth multitasking, storage for keeping files.

Why does my computer show less storage than I bought?

The operating system (Windows, Mac, or Linux) takes up space, and manufacturers measure drives differently than the operating system does. A 1 TB drive typically shows around 930 GB available because of these differences and the space the OS uses.

Can I upgrade my processor or graphics card?

On a desktop, yes—you can replace the processor and add a graphics card. On a laptop, usually no—most components are soldered to the motherboard. RAM and storage are often upgradeable on both. Check your specific model's manual or contact the manufacturer to know for sure.

What specs do I need to run a video call or stream video?

For video calls (Zoom, Teams, Google Meet), you need at least 4 GB of RAM and a processor from the last five years. For streaming video (YouTube, Netflix), 2 GB of RAM is enough. For streaming or recording your own video, 8 GB of RAM and a processor from the last three years is safer.

Is my computer too old to use?

If your processor is from 2015 or later and you have at least 8 GB of RAM, you can still use it for email, web browsing, and documents. Older machines slow down because the operating system gets heavier with updates, not because the hardware fails. Adding more RAM or replacing the hard drive with an SSD often helps.
