The fastest way to check your PC specs

The quickest route is the System Information tool built into Windows. Press the Windows key and the letter R at the same time to open the Run dialog, type msinfo32, and press Enter. A window will open showing your processor, RAM, system type, and Windows version all in one place.

If you are on a Mac, click the Apple menu in the top left corner, select About This Mac, and you will see your processor, memory, graphics card, and macOS version when ready.

Both methods take under 30 seconds and show the information most people need. If you need more detail — like your exact graphics card model, storage drive type, or motherboard — the steps below will walk you through finding those.

Key Takeaways

  • Windows users can open System Information by pressing Windows key + R, typing msinfo32, and pressing Enter to see processor, RAM, and system type when ready.
  • Mac users can click the Apple menu and select About This Mac to view processor, memory, graphics card, and operating system version.
  • For detailed information like storage type and motherboard model, use Device Manager on Windows or System Report on Mac.
  • Third-party tools like CPU-Z and GPU-Z show processor and graphics card details in a simpler format than built-in tools.
  • Your PC's original documentation or the manufacturer's support website can confirm specs if built-in tools show incomplete information.

Finding your processor and RAM in Windows

Open System Information as described above. Look for the line labeled Processor — this shows your CPU model and speed. The line labeled Installed RAM shows your total memory in gigabytes.

If you want to know how much RAM is actually available for use (some is reserved by Windows), look for Available Physical Memory in the same window. The difference between installed and available is normal and does not mean anything is broken.

Write down both numbers if you are shopping for upgrades or troubleshooting a slow computer. Many programs list their minimum processor and RAM requirements, and knowing your exact specs lets you check whether your machine can run them.

Checking your graphics card and storage drive

System Information does not always show your graphics card clearly. To see it, open Device Manager by pressing Windows key + R, typing devmgmt.msc, and pressing Enter. Look for the section labeled Display adapters and click the arrow next to it. Your graphics card model will be listed there.

For storage information, right-click the C: drive (or whichever drive you want to check) in File Explorer and select Properties. This shows total capacity and how much space is in use. To see whether your drive is a solid-state drive (SSD) or older hard drive (HDD), open Device Manager again and look under Disk drives. The model name usually includes "SSD" if it is a solid-state drive.

If Device Manager shows a graphics card labeled "Intel UHD Graphics" or "AMD Radeon Graphics," that is integrated graphics built into your processor, not a separate card. Integrated graphics share your system RAM and are slower than dedicated graphics cards, which have their own memory.

Using third-party tools for detailed specs

CPU-Z is a free tool that shows your processor model, speed, and core count in a cleaner format than System Information. read it from cpuid.com, run the installer, and open the program. The Processor tab shows everything about your CPU; the Memory tab shows your RAM type and speed.

GPU-Z, also free from techpowerup.com, displays your graphics card model, memory amount, and driver version. If you have both integrated and dedicated graphics, GPU-Z will show both and tell you which one is currently active.

These tools are safe and do not install anything permanently — you can delete them after checking your specs. They are useful if you are comparing your computer to a game's system requirements or deciding whether to upgrade.

Finding specs on a Mac

Click the Apple menu and select About This Mac. The Overview tab shows your processor, memory, graphics card, and macOS version. Click the System Report button at the bottom to see more detail, including your storage drive type, serial number, and exact model identifier.

If you want to know how much storage space is in use, click Storage in the left sidebar of System Report. This shows each drive and how much capacity it has. The Overview tab of About This Mac also shows a straightforward bar graph of storage use.

For graphics card details, click Graphics/Displays in System Report. This shows your GPU model, memory, and driver version — the same information GPU-Z provides on Windows.

Checking your specs before buying software or games

Most software and games list minimum system requirements on their store page or website. Compare those numbers to your specs: your processor speed should meet or exceed the minimum, your RAM should be at least as much as listed, and your graphics card should be the same model or newer.

If a game requires an NVIDIA GeForce RTX 3060 and you have an RTX 2080, you have an older card that may run the game but at lower frame rates or graphics settings. If you have integrated graphics and the game requires a dedicated card, the game will likely not run well or at all.

Processor speed is listed in gigahertz (GHz). A requirement for 3.5 GHz means your processor's base speed should be at least 3.5 GHz — you can find this in System Information or CPU-Z under the Processor line.

What to do if your specs look incomplete or wrong

If System Information shows "Unknown" for your processor or graphics card, your drivers may be out of date. Visit your PC manufacturer's support website (Dell, HP, Lenovo, Asus, etc.), enter your model number, and read the latest chipset and graphics drivers. Restart your computer after installing them and check System Information again.

Your PC model number is usually on a sticker on the back or bottom of your computer. If you cannot find it, open System Information and look for System Model — that is your model number.

If you built your own PC or inherited one without documentation, the manufacturer's website for your motherboard (ASUS, MSI, Gigabyte, etc.) can confirm what components are compatible with your system. You can find your motherboard model in System Information under BaseBoard Product.

Frequently Asked Questions

What is the difference between processor speed and number of cores?

Processor speed (measured in GHz) is how fast each core runs. Number of cores is how many processors your CPU has — a quad-core processor has four cores. A processor with four cores at 3.5 GHz will handle multitasking better than a single-core processor at 4.0 GHz, even though the single core is technically faster.

Why does my available RAM show less than my installed RAM?

Windows and your graphics card reserve some RAM for their own use. If you have 16 GB installed and 14 GB available, that is normal. The reserved memory is not broken or wasted — it is being used by the system. If available RAM is much lower than expected, you may have a program running in the background using memory.

Can I upgrade my processor or graphics card?

Graphics cards can usually be upgraded if you have a desktop PC with a free slot and adequate power supply. Processors are harder — they require a compatible motherboard socket, and upgrading often means replacing the motherboard too. Laptops rarely allow either upgrade. Check your motherboard model in System Information and visit the manufacturer's website to see what upgrades are possible.

What does "integrated graphics" mean, and is it good enough for gaming?

Integrated graphics is a processor with a built-in graphics chip that shares your system RAM instead of having its own memory. It is adequate for everyday tasks and older games but too slow for modern games at high settings. If you want to play new games, you need a dedicated graphics card.

Where do I find my Windows or macOS version number?

On Windows, open System Information and look for OS Name and OS Version. On Mac, click About This Mac and look at the top line next to the macOS name. You will see something like "macOS Sonoma 14.1" — that is your version.
