What GPU Do I Have? (Detector)

Your browser can identify your graphics card from its WebGL renderer name — open the tool below and it detects your GPU and shows full specs, with no download. It can’t read live clocks or temperatures the way the GPU-Z desktop app does.

Quick answer. This tool reads the graphics “renderer” your browser exposes and matches it to a known GPU, then displays the full specifications instantly — nothing to install. If your browser hides that information for privacy, just pick your card from the list and get the same spec sheet. It’s a fast, online GPU-Z alternative for identifying your card, not for deep hardware diagnostics.

How the browser detects your GPU

Modern browsers include WebGL, the technology that renders 3D graphics on web pages, and WebGL can report the name of the graphics hardware it’s running on. This tool asks for that “unmasked renderer” string and matches it against a library of known GPUs to identify your card, then pulls up its specs. It all happens locally in your browser in a fraction of a second — no upload, no account, no software.

Because it relies on the renderer string, results depend on your browser and settings. Most desktop Chrome and Edge installations report the card clearly. Some browsers, notably privacy-focused ones or certain Firefox configurations, deliberately mask or generalize the string, and some route graphics through a translation layer called ANGLE, which can produce a less specific name. When that happens, detection may fail or return a generic result — that’s expected, and the manual dropdown below the detector will get you the exact specs anyway.

Other ways to check your GPU (Windows and Mac)

(These steps can carry HowTo schema.)

If you’d rather check outside the browser, every operating system has a built-in way:

• Windows Task Manager: press Ctrl+Shift+Esc, open the Performance tab, and select GPU — the model name appears at the top right.
• Windows Device Manager: right-click Start, open Device Manager, and expand Display adapters.
• DirectX Diagnostic Tool: press Win+R, type dxdiag, press Enter, and read the Display tab.
• Mac: click the Apple menu, choose About This Mac, and look under Graphics (or open System Information for detail).

These methods show the model reliably even when the browser can’t, and they’re worth knowing if you’re about to update drivers or check compatibility.

Browser detection vs GPU-Z: what’s the difference

It’s worth being clear about limits. A browser can only read the renderer name your system exposes, which is enough to identify the model but not to inspect it. The desktop GPU-Z application reads far more: live core and memory clock speeds, real-time temperatures and power draw, exact VRAM type and size, BIOS version, and sensor logs. So think of this tool as the fast way to answer “which card is this?” — ideal when you’re helping a friend, checking a prebuilt, or confirming a listing — and reach for a desktop utility when you need live diagnostics or overclock monitoring. Being upfront about that keeps expectations right and saves you chasing data a browser fundamentally can’t provide.

Found your GPU? Here’s what to do next

Once you know your card, the useful next steps are only a click away. See how it stacks up against others in the GPU comparison tool, check what it’s worth on the used market with the used GPU price checker, or, if it’s showing its age, decide whether to repair or replace it. And if you need more horsepower than your card can deliver — for a big render or an AI model that won’t fit in its memory — you can rent a more powerful GPU in the cloud and use it in minutes.

How do I know what graphics card I have? The quickest way is the tool above, which detects it in your browser. Otherwise, on Windows open Task Manager’s Performance tab and select GPU, or expand Display adapters in Device Manager; on Mac, check About This Mac under Graphics.

Is there an online GPU-Z? This tool is a lightweight online alternative for identifying your GPU and viewing its specs without a download. For live clocks, temperatures, and sensor data, you’ll still want the GPU-Z desktop app, since browsers can’t read that information.

Why does my GPU show as “ANGLE” or a generic name? Some browsers mask the renderer string for privacy or route WebGL through a translation layer called ANGLE, which returns a generic label instead of your exact model. When that happens, use the dropdown to select your card manually and view its full specs.
