rendering performance

Because Light Bench is built on the same unique GPU path tracing engine as Light Tracer Render, you can reliably forecast your graphics card's performance in real-life workflows. You can test and compare graphics cards from different vendors, such as NVIDIA, AMD, and Intel. Utilize our online score database to rank and compare GPUs by performance and price.

Overclock to the max!

Light Bench is an extreme GPU stability test that is very sensitive to any calculation and video memory errors resulting from overclocking or other factors like insufficient or excessive voltages, power supply instability, overheating issues, etc. By quickly identifying problems, the amount of time needed for tinkering and testing can be reduced dramatically!

If you run the Web version on a dual-GPU laptop, ensure your browser uses a dedicated GPU

We recommend to use at least GeForce GTX 670 / GeForce GTX 1050 / AMD Radeon RX 560 / Apple M1
