Frequently Asked Questions

Q #1) What is the benchmark software?

Answer: A benchmark app is used for testing computer performance. They are mainly used to compare the performance of computer systems across different hardware. GPU benchmark app specifically tests the performance of the graphics card.

Q #2) How do I check if my GPU is bad?

Answer: If your computer crashes during a GPU benchmark test, your graphics card may be faulty. Remember that low benchmark scores don’t necessarily indicate a faulty GPU. Poor GPU test scores are caused due to old drivers, overheating, or power supply issues.

Q #3) Why is my GPU not detected?

Answer: A GPU may not be detected by a benchmarking app if you have an old model graphics card. Another reason for the app not detecting your GPU is that the drivers are outdated.

Q #4) What is real-time GPU benchmarking?

Answer: Real-time benchmarking software measures graphics card performance, during the actual gameplay. Also known as real-world benchmarking, it involves measuring the frames per second (fps) of a game during gameplay.

Q #5) How we can use a GPU benchmark app?

Answer: Download a GPU benchmark app and run the software. You should compare the benchmark score of your card with the average score for the same card. A significantly lower score shows an issue with the graphics card.
