How to Check What GPU You Have & Test Its Performance

MyDeviceScan Β· Updated January 2026 Β· 6 min read

Not sure what graphics card is inside your computer? Want to know if it's powerful enough for the games or software you're running? This guide covers every method to identify your GPU and understand what its specs actually mean.

Quick Method: Check Online (No Install)

The fastest way to identify your GPU is to use MyDeviceScan's GPU Check tool. It reads your graphics card information directly from your browser using WebGL β€” no download or installation required. You'll see your GPU model, VRAM (estimated), display resolution, CPU cores, and RAM in seconds.

Note: browsers may display a slightly simplified name (e.g., "ANGLE (NVIDIA, NVIDIA GeForce RTX 4070...)" β€” this is normal and includes the actual card name.

Check GPU on Windows

Method 1: Task Manager

  1. Press Ctrl + Shift + Esc to open Task Manager
  2. Click the Performance tab
  3. Click GPU 0 in the left sidebar
  4. Your GPU model appears in the top right
  5. VRAM shown as "Dedicated GPU Memory"

Method 2: Device Manager

  1. Right-click Start β†’ Device Manager
  2. Expand "Display adapters"
  3. Your GPU(s) are listed here

Method 3: DirectX Diagnostic

  1. Press Win + R, type "dxdiag" and press Enter
  2. Click the Display tab
  3. Full GPU name, VRAM, and driver version shown

Check GPU on Mac

  1. Click the Apple menu β†’ About This Mac
  2. Look for "Graphics" in the overview
  3. For more detail: System Report β†’ Graphics/Displays

Apple Silicon Macs (M1, M2, M3, M4) have integrated GPUs β€” the GPU is built into the same chip as the CPU. These are listed as "Apple M2 Pro" etc. rather than a separate GPU model.

Understanding GPU Specs

SpecWhat It MeansWhy It Matters
VRAM (GB)Dedicated video memoryMore VRAM = higher textures, higher resolution gaming
CUDA Cores / ShadersProcessing unitsMore cores = faster rendering
Memory BandwidthData transfer speedAffects 4K performance and large texture loading
TDP (Watts)Power consumptionHigher TDP = more performance but more heat/power
ArchitectureGPU generation (Ada, RDNA 3, etc.)Newer = better performance per watt, ray tracing

How Much VRAM Do You Need?
