How do I find out which graphics card I have?

On Windows open the Task Manager (Ctrl + Shift + Esc), go to Performance and click GPU. The model name is in the top right, the VRAM is listed as dedicated GPU memory. In Steam, Help › System Information shows it too.

How much VRAM do I have?

Task Manager › Performance › GPU shows it as "Dedicated GPU memory". In DxDiag (Win + R, dxdiag) it is "Display Memory (VRAM)" on the Display tab. Integrated graphics have no own VRAM and use part of the system RAM.

Can I check my PC hardware without installing anything?

Yes. Task Manager, DxDiag and msinfo32 are built into Windows, and Steam shows a full list under Help › System Information. Nothing needs to be downloaded.

How to check your PC hardware: GPU, CPU, RAM and VRAM

Short answer: on Windows, press Ctrl + Shift + Esc and open the Performance tab of the Task Manager. It shows your processor, memory and graphics card, including dedicated GPU memory (VRAM). If you play on Steam, Steam › Help › System Information lists everything in one place.

Why these four parts matter

Game requirements name four things: the graphics card (GPU), the processor (CPU), the amount of RAM and, more and more often, the graphics memory (VRAM). The GPU decides most of your frame rate, the CPU limits it in busy scenes and fast shooters, and too little RAM or VRAM causes stutter even when the other parts are fast enough.

Windows: Task Manager (fastest)

Press Ctrl + Shift + Esc and click Performance (on a compact view, first click More details).
CPU: the exact model is in the top right, for example "AMD Ryzen 5 5600".
Memory: total RAM, its speed and "Slots used". One stick in a two-slot board often means single-channel memory, which costs FPS in CPU-heavy games.
GPU 0 / GPU 1: the graphics card model and "Dedicated GPU memory", which is your VRAM. Laptops often show two GPUs: the processor's integrated graphics and the dedicated card. For games, the dedicated one counts.

Windows: other built-in ways

DxDiag: press Win + R, type dxdiag. The System tab shows CPU and RAM, the Display tab the GPU and its "Display Memory (VRAM)".
System Information: Win + R, msinfo32. Good for the exact Windows version and the motherboard.
Settings › System › About: processor and installed RAM, but no graphics card.

Steam (any system)

In the Steam client open Help › System Information. It lists processor, memory, video card, driver version and VRAM. On doesitrun you can paste that text straight into the hardware box and every field is filled in for you.

Linux and Steam Deck

Graphics card: lspci | grep -i vga
Processor: lscpu
RAM: free -h
Driver and renderer: glxinfo -B (in the mesa-utils package on most distributions)

On a Steam Deck you don't need to look anything up: every Deck has the same chip. See which games run on the Steam Deck.

macOS

Apple menu › About This Mac shows the chip and memory. Most Steam games are Windows-only, so on a Mac the useful question is usually whether a game has a native macOS version.

Pitfalls when reading the names

Laptop GPUs carry the same names as desktop cards but are usually slower, depending on the power limit the laptop maker chose. "RTX 4060 Laptop GPU" is not a desktop RTX 4060.
"Intel UHD", "Iris Xe", "Radeon Graphics" are integrated graphics. They share system RAM instead of having their own VRAM.
The same GPU name can come with different VRAM (for example 8 GB and 16 GB versions), so check the memory line too.

Next step: now that you know your parts, see what your whole Steam library runs at, with estimated FPS per game.
