How to Check Your PC Specs for Gaming

PC Hardware Specs

Before buying a game on PC, you need to know whether your hardware meets the system requirements. This sounds simple, but many players are unsure how to find their exact CPU, GPU, and RAM specifications — especially if they are using a pre-built PC or a laptop that came without detailed hardware documentation. This guide shows you exactly how to find every important spec on a Windows PC in 2026, what each component means for gaming performance, and how to use that information to make better purchase decisions.

The Four Specs That Matter Most for Gaming

Game system requirements list four main hardware components. Here is what each one does and why it matters:

Component What it does Impact on gaming
GPU (Graphics Card) Renders the 3D visuals Most important for frame rate and visual quality. The GPU is the bottleneck in almost all modern games.
CPU (Processor) Handles game logic, AI, physics Important for CPU-heavy games (strategy, simulation, open world). Less critical than GPU for most titles.
RAM (Memory) Temporarily stores active game data 16 GB is the standard minimum in 2026. Below 8 GB will cause stuttering in most modern games.
Storage Stores the game files NVMe SSD dramatically reduces load times vs HDD. Less impact on frame rate but critical for open-world streaming.

Method 1: Windows System Information (Fastest)

The quickest way to see your CPU and RAM is through the built-in System Information panel.

Step 1

Open System Information

Press Windows + R, type msinfo32, and press Enter. This opens the System Information window with a full summary of your hardware.

Step 2

Find your CPU and RAM

In the System Summary panel, look for Processor (your CPU model) and Installed Physical Memory (RAM). You will see values like "Intel Core i7-12700K" and "16.0 GB".

Step 3

Find your GPU

In the left sidebar, expand Components → Display. You will see your GPU name under "Name" (for example, "NVIDIA GeForce RTX 4070") and the VRAM under "Adapter RAM".

Method 2: Task Manager (Quick GPU Check)

Windows Task Manager shows real-time GPU usage and lets you see all installed GPUs.

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Click the Performance tab.
  3. You will see GPU entries in the left sidebar. If you have both integrated graphics (Intel or AMD iGPU) and a discrete GPU (NVIDIA or AMD), both will appear here. The dedicated GPU is the one that will run games.
  4. Click on your GPU entry to see its name, VRAM (Dedicated GPU memory), and current utilization.

💡 Integrated vs. Dedicated GPU: Many laptops have both an integrated GPU (built into the CPU, labelled "Intel UHD", "Intel Iris", or "AMD Radeon Graphics") and a dedicated GPU (NVIDIA GeForce or AMD Radeon RX). Games always use the dedicated GPU. Make sure you are comparing the dedicated GPU against system requirements, not the integrated one.

Method 3: DirectX Diagnostic Tool (Most Complete)

The DirectX Diagnostic Tool (DxDiag) gives the most complete hardware information in one place and is useful if other methods show incomplete data.

Step 1

Open DxDiag

Press Windows + R, type dxdiag, and press Enter. Wait a few seconds for it to finish gathering information.

Step 2

System tab — CPU and RAM

The System tab shows your Processor (CPU) and Memory (RAM) at the top. It also shows your current Windows version and DirectX version, both of which appear in game system requirements.

Step 3

Display tab — GPU

Click the Display tab (there may be multiple if you have more than one GPU). The "Name" field shows your GPU model, and "Display Memory (VRAM)" shows the dedicated VRAM. Your gaming GPU is usually labelled with its manufacturer name (NVIDIA or AMD/ATI).

Method 4: GPU-Z and CPU-Z (Most Detailed)

For the most detailed hardware information — including exact GPU architecture, memory type, and CPU clock speeds — two free tools are considered the standard:

These tools are not necessary for most users, but they are helpful if you are trying to determine whether to upgrade a specific component or if your hardware is being reported incorrectly by the basic Windows tools.

How to Use Your Specs to Check Game Compatibility

Once you know your CPU, GPU, RAM, and storage, comparing them against game system requirements is straightforward. Every game on Steam has a minimum and recommended specification listed on its store page. The minimum means the game will run but likely at low settings and reduced frame rates. The recommended means you can expect the game to run well at medium to high settings.

What to look for in requirements

💡 Use the GameScanAI PC Specs Checker on our homepage to automatically compare your hardware against any game's requirements. Click "Auto Detect" to read your GPU through the browser, or enter your specs manually for an instant compatibility report.
