Instantly detect your graphics card, CPU, RAM, screen resolution, OS and browser — no download required.
You know your hardware — see if your connection can keep up.
Your GPU (Graphics Processing Unit) is the chip responsible for rendering everything you see on screen — from desktop icons to 3D games and video playback. Unlike your CPU which handles general computing tasks, the GPU is specifically optimized for parallel processing of visual data.
This tool reads your GPU information directly from your browser using the WebGL API — no installation required. It shows your graphics card model, estimated VRAM, display resolution, refresh rate, CPU core count, and total system RAM, which is handy when installing games, updating drivers, or comparing hardware.
The main GPU makers are NVIDIA (GeForce), AMD (Radeon), and Intel (Arc and integrated UHD Graphics), while Apple Silicon Macs use GPU cores built into the M-series chips. If you'd rather verify in your operating system, you can use dxdiag or Task Manager on Windows, About This Mac → More Info → Graphics on macOS, or lspci | grep VGA (or nvidia-smi) on Linux — the FAQ below has the exact steps.
Browsers report GPU names through a rendering layer (ANGLE on Windows, Metal on Mac). You may see a prefix like "ANGLE (NVIDIA, ...)" — the actual GPU name follows in parentheses. This is normal and shows your real graphics card.
Web browsers cannot directly read hardware VRAM specifications for security reasons. The displayed value is estimated from WebGL capabilities and may differ from your actual VRAM. Use Task Manager (Windows) or GPU-Z for exact values.
Integrated GPUs (Intel UHD, AMD Radeon Graphics, Apple M-series) share system RAM and are built into the CPU. Dedicated GPUs (NVIDIA GeForce, AMD Radeon RX) have their own VRAM and deliver significantly higher performance for gaming and creative work.
1080p gaming: RTX 4060 or RX 7600 (8 GB VRAM). 1440p gaming: RTX 4070 or RX 7800 XT (12 GB VRAM). 4K gaming: RTX 4080/5080 or RX 7900 XTX (16–24 GB VRAM).
Press Ctrl+Shift+Esc → Performance tab → click GPU 0. Or run dxdiag from the Run dialog (Win+R) and check the Display tab for full GPU details including VRAM and driver version.
SwiftShader is a software-based GPU renderer used when no hardware GPU is available (e.g., virtual machines, headless servers). It is extremely slow and not suitable for gaming or graphical work.
In most laptops, the GPU is soldered to the motherboard and cannot be upgraded. External GPU enclosures (eGPU) via Thunderbolt 3/4 are an option for some laptops, though performance is limited by the interface bandwidth.
Windows에서 그래픽 카드를 확인하려면: Win+R을 누르고 dxdiag를 입력한 후 Enter → 디스플레이 탭에서 GPU 모델을 확인. 또는 이 페이지를 열면 자동으로 그래픽 카드 모델이 감지됩니다.
Logical cores are the total number of processing threads your CPU can handle simultaneously, including hyper-threading. For example, a 6-core CPU with hyper-threading shows as 12 logical cores. More cores generally means better multitasking and performance in multi-threaded applications.
For privacy reasons, browsers only report RAM in rounded buckets (0.25, 0.5, 1, 2, 4, 8 GB). A device with 16GB or 32GB will report as "8 GB" — this is a browser limitation, not a real reading. Use Task Manager or System Info on Windows for the exact amount.
