Free tool to measure and compare GPU rendering performance
Light Bench uses the same engine as Light Tracer Render, so you can trust its real‑world performance forecasts. Evaluate NVIDIA, AMD, Intel, and other GPUs, then rank them by speed and value in our online database.
Compare your Light Bench score against identical GPUs from other users. Published scores are medians of real results, helping you gauge your system's performance and identify limiting factors.
Light Bench is an extreme GPU stability test, sensitive to calculation and memory errors from overclocking, voltage issues, power instability, or overheating. It spots problems fast – less tinkering, more optimizing.
Top-10 GPUs ranked by rendering performance in the Light Tracer engine
Higher scores are better, doubling the score indicates halving rendering time
Light Bench is based on the Light Tracer Render and harnesses its power in a portable, free tool that renders several test scenes in about 3 minutes to assess the performance of your graphics card.
Light Bench measures your GPU's rendering speed in million samples per second (MSamples/sec) across several scenes, then sums the results for a reliable overall performance score.
On Windows with a compatible NVIDIA or AMD GPU, Light Bench uses hardware ray tracing. On all other systems (including macOS), it runs on our highly efficient software ray tracing engine.
Yes. Scores are linear (2x score = 2x faster rendering). You can compare software vs. hardware ray tracing modes, and even Windows vs. macOS systems.
