Test GPU performance and stability with real-time temperature monitoring and benchmark reports. Perfect for gamers and PC hardware enthusiasts.
Run Benchmark
When you are unsure if your graphics card is performing as it should or are worried about thermal issues, the GPU Tester uses WebGL/WebGPU interfaces through your browser to run a real-time rendering stress test. It outputs key metrics like frame rate (FPS), temperature, and stability to help you evaluate your GPU's health.
Q: Will an online GPU test damage my graphics card?
A: No. The test simulates normal gaming workloads. As long as your cooling system is functioning properly, short-term testing is completely safe.
Q: Why is my RTX 3070 benchmark score lower than average?
A: Graphics driver versions, background processes, case airflow, and power supply can all affect the results. We recommend updating your drivers, closing unnecessary software, and testing again.
Please update your graphics drivers and close background apps before testing. If the core temperature consistently exceeds 90°C, stop the test immediately and check your cooling system. Ensure hardware acceleration is enabled in your browser settings.
For NVIDIA users, we recommend setting the Power Management Mode to "Prefer maximum performance" in the NVIDIA Control Panel. Typical test output: An RTX 3060 at 1080p resolution averages 110-130 FPS, with a core temperature of 65-75°C, and a stability score of over 98%.
