3DMark and GPU benchmark apps

A recent XDA piece pointed out that most people run their Nvidia GPU with the wrong power and image-scaling defaults, and that a few Control Panel changes buy real performance. The way to prove it is with a benchmark: a repeatable workload that produces a number before and after the change. These are the best apps for GPU benchmarking on desktop, from full DirectX 12 test suites to stress tools that push the card until it throttles.

The apps

1. 3DMark – Best DirectX 12 and Vulkan benchmark

3DMark from UL Solutions is the benchmark hardware reviewers cite. Time Spy tests DirectX 12 performance, Port Royal tests real-time ray tracing, Steel Nomad tests Vulkan on modern hardware, and Speed Way stresses DirectX 12 Ultimate features. Results upload to a public database so you can compare your run against every card in the market.

Where it falls short: Windows only. The free version has a few locked demos, and the paid version is a one-time $34.99.

Pricing:

Platforms: Windows

Bottom line: The number every GPU reviewer publishes. Run this if you want to compare with the wider world.

2. Unigine Superposition – Best for a modern ray-traced workload

Unigine Superposition stresses a card with a physics-heavy scene and optional ray-traced effects. It runs at 1080p through 4K presets, has a VR mode for HMDs, and includes a stress mode that repeats a workload until temperatures stabilise. The output shows minimum and maximum framerate alongside the average, which matters for stutter analysis.

Where it falls short: No macOS support. The Pro version’s $19.95 unlocks the stress-test loop and custom resolutions.

Pricing:

Platforms: Windows, Linux

Bottom line: The right pick for a Vulkan-focused test with a modern ray-traced scene.

3. Unigine Heaven – Best free classic tessellation test

Unigine Heaven is the same team’s older benchmark and remains one of the most reproducible tests around. It uses tessellation heavily, which stresses the geometry pipeline. Because it has stayed the same for years, you can compare a card today against reviews from a decade ago.

Where it falls short: DirectX 11 only, so it does not exercise modern features like ray tracing or DirectX 12 Ultimate. macOS support is limited to older OS versions.

Pricing:

Platforms: Windows, macOS, Linux

Bottom line: The historical baseline. If you want to know how your new card compares against a review from years ago, run this.

4. FurMark – Best GPU stress test

FurMark loops a fur-rendering scene that pushes a GPU harder than nearly any real workload. It is the tool to prove a fan curve is aggressive enough, that an overclock is stable, or that a laptop can maintain performance under sustained load. GPU-Z is bundled for temperature and power logging.

Where it falls short: Runs so hot that some manufacturers warn against it on laptops. Not a benchmark for game-relevant scores.

Pricing:

Platforms: Windows, Linux

Bottom line: The stress tester. Use it to prove stability, not to score a card.

5. UserBenchmark – Best for a quick community comparison

UserBenchmark ships a small executable that runs a 60-second workload and uploads the result to a public database. The comparison view shows how your card lines up against every other model, and how your specific unit compares to the average of the same card.

Where it falls short: The methodology has been criticised, and CPU/GPU weighting in the composite score has caused controversy. Use it only for a quick sanity check.

Pricing:

Platforms: Windows

Bottom line: Fine for a five-minute reality check, not for a review-grade result.

6. GPU-Z – Best for real-time sensor logging

GPU-Z is not a benchmark, it is a sensor tool. It shows core and memory clocks, temperature, power draw, and load, and it can log every sensor to a CSV file at up to ten times per second. Pair it with any of the benchmarks above to see what happened to the card during the run.

Where it falls short: Windows only, and read-only. It monitors, it does not tune.

Pricing:

Platforms: Windows

Bottom line: The sensor tool every benchmark session needs alongside it.

7. Geekbench 6 – Best for cross-platform GPU compute

Geekbench 6 runs OpenCL, CUDA, Vulkan, and Metal compute workloads and produces a single score comparable across every OS and card the app supports. Useful when the workload is compute (video encoding, science, machine learning) rather than gaming.

Where it falls short: The gaming-relevance of the compute score is limited. Pro edition adds command-line usage for $99.99.

Pricing:

Platforms: Windows, macOS, Linux

Bottom line: The one benchmark on the list that runs on macOS with a modern Metal workload.

How to pick the right one

If the goal is a headline number to compare against reviews, run 3DMark Time Spy for DirectX 12 and Unigine Superposition for Vulkan. Before and after any Control Panel tweak, run Unigine Heaven or Superposition three times each and average the score. Use FurMark to prove stability, not to score, and only when you have thermal headroom. GPU-Z should always be logging in the background so you can see whether the card thermal-throttled during the run. UserBenchmark is fine for a first sanity check on a new machine. On macOS or Linux, Geekbench 6 is the closest thing to a universal benchmark, and Superposition or Heaven cover the graphics side.

Always run three passes and discard the first. Windows does aggressive I/O and driver caching on a fresh boot, and the first pass is usually a few percentage points slower.

FAQ

What is the best free GPU benchmark?

3DMark’s Steel Nomad Demo, Unigine Superposition Basic Edition, and Unigine Heaven cover the three main workloads at no cost. Run all three for a rounded picture.

How often should I benchmark my GPU?

After every driver update if you care about performance, after any Control Panel or Adrenalin setting change, and once a season to check for thermal degradation from dust buildup.

Can I benchmark integrated graphics?

Yes, all seven apps run on integrated graphics. Expect scores an order of magnitude below a discrete GPU, and use the 1080p Low or Night Raid presets so the test finishes in a reasonable time.

Is UserBenchmark accurate?

Its raw framerate numbers are fine. The composite comparison scores have been criticised because the weighting was changed in ways that hurt certain vendors. Treat the number as a rough guide, not a verdict.

Which benchmark stresses ray tracing hardest?

3DMark Port Royal is the classic ray-tracing test. Unigine Superposition has a ray-traced mode that stresses reflections and lighting. Both are reasonable proxies for real ray-traced game workloads.
