GPU Benchmark — Test Your Graphics Online
Benchmark your graphics card or integrated GPU in the browser. The test renders an increasingly heavy shader and adapts the load to find your GPU's sustained throughput — so the score isn't capped by your monitor's refresh rate. Compare your result on the leaderboard, or run the 60-second stress test to check for thermal throttling.
Plug laptops in for a fair score. Fans spinning up during the test is normal — that's the point.

Understanding your GPU score
The benchmark renders a heavy WebGL shader and adapts the workload to your graphics hardware, measuring sustained shader throughput. Because the score is work multiplied by frame rate, fast GPUs are not capped by monitor refresh rate.
What this test checks
- Sustained shader throughput under an adaptive load that targets your GPU's limit.
- Detected GPU model via the browser's renderer information, shown on the leaderboard.
- Live frame rate and shader load while the test runs.
- An optional 60-second stress test comparing early and late performance for throttle detection.
How to understand your results
- Integrated graphics typically score in the hundreds to low thousands; dedicated gaming cards score many times higher.
- On battery, or with the browser's hardware acceleration disabled, scores collapse - check both before judging hardware.
- A blank or generic GPU name means the browser is hiding renderer details for privacy - the score is still valid.
- Stress-test drops beyond about 15 percent indicate heat build-up in the GPU or shared laptop cooling.
Common problems and fixes
Score is tiny on a gaming PC
Check the browser is using the dedicated GPU, not the integrated one: Windows Settings > System > Display > Graphics lets you force high performance for your browser.
WebGL not available
Enable hardware acceleration in your browser settings and update graphics drivers, then restart the browser.
Laptop scores lower than yesterday
Almost always power state: battery saver, unplugged, or a hot room. Benchmarks are only comparable under the same conditions.
Screen flickers during the test
Heavy GPU load can trigger brief flicker on marginal drivers. Update the graphics driver; if flicker appears in games too, investigate cooling and the PSU on desktops.
FAQ
Is this the same as a native GPU benchmark?
No - it measures browser-accessible WebGL throughput, which is ideal for quick comparisons and leaderboards but less exhaustive than native tools.
Why is my GPU name not shown?
Some browsers mask the renderer string for privacy. The benchmark still runs and scores normally.
Does the test use my dedicated GPU or integrated graphics?
Whichever the browser is assigned. On dual-GPU laptops you can force the browser onto the dedicated GPU in your OS graphics settings.
Is a 60-second GPU stress test safe?
Yes - it is ordinary rendering load, the same as a game. Modern GPUs throttle themselves long before any risk.
Browser-based test disclaimer
TestMyPC results are browser-based and may vary depending on your device, browser, operating system, permissions, drivers, connection, power settings and connected accessories. Use these tools as practical first checks, then confirm important faults with operating-system diagnostics, manufacturer tools or a qualified technician where needed.
