Blender Open Data Benchmark is a free, standalone Mac application that stress-tests your machine's CPU and GPU using real Blender rendering workloads, then submits your results to a global public database so you can compare your hardware against thousands of other systems.
What is Blender Open Data Benchmark?
Blender Open Data Benchmark is the official benchmarking tool published by the Blender Foundation. It runs a fixed suite of Blender rendering scenes — the same ones used by artists and studios worldwide — and measures how quickly your hardware completes them. Because the scenes are standardised and the results are crowd-sourced, you get a genuinely meaningful comparison rather than a synthetic number cooked up by a hardware vendor.
The application is completely separate from Blender itself; you do not need Blender installed. It ships its own renderer, guarantees a reproducible environment, and quietly handles the submission to opendata.blender.org when you're done.
What does Blender Open Data Benchmark do best?
It excels at giving 3D artists and Mac buyers an honest, apples-to-apples render performance number. Where synthetic benchmarks like Geekbench or Cinebench measure abstract compute primitives, Blender Open Data Benchmark measures the exact workload you actually care about: path-tracing a complex scene. I ran it before and after upgrading RAM and the delta mapped almost perfectly to real-world Blender project times.
- CPU and GPU modes — you can benchmark the CPU renderer (Cycles CPU), the GPU renderer (Cycles GPU / Metal on Apple Silicon), or both in a single run.
- Apple Silicon support — the GPU path uses Metal, so M-series chips get a fair shake rather than being penalised by an OpenCL path designed for discrete GPUs.
- Public leaderboard — every submission lands in the open database, searchable by device name, OS, and renderer. You can filter to "Apple M4 Pro" and instantly see the distribution of real-world scores.
- Reproducible scenes — the benchmark scenes are versioned and archived, so a score from two years ago is still comparable to one from today.
Who should use Blender Open Data Benchmark?
Anyone who renders in Blender — or is thinking about buying hardware to do so — should run this before making decisions. It is particularly valuable for Mac users evaluating whether a base M4 chip is sufficient or whether the Pro/Max/Ultra GPU cores justify the cost. Studio leads can use it to build an objective fleet comparison across their workstations. If you are not a Blender user at all, alternatives like Cinebench 2024 or Geekbench 6 will give you broader app-agnostic scores with less setup.
Is Blender Open Data Benchmark free?
Yes — it is completely free to download and run. There is no Pro tier, no account requirement to run the benchmark locally, and the result database at opendata.blender.org is publicly accessible without registration. An optional account lets you claim and track your own submissions over time, which is useful if you benchmark after each macOS update or hardware change.
How does Blender Open Data Benchmark compare to Cinebench?
Cinebench (from Maxon, the company behind Cinema 4D) is the more famous name and runs faster — a single Cinebench 2024 nT pass takes roughly ten minutes versus Blender's longer multi-scene suite. Cinebench measures raw CPU multi-thread throughput using Cinema 4D's renderer, which correlates well with general CPU performance. Blender Open Data Benchmark is slower to run but directly predictive of Blender render times, includes a GPU path that Cinebench's free tier does not, and feeds a larger public dataset. If you use Blender, this benchmark is more actionable; if you want a quick cross-app CPU proxy, Cinebench is faster to run. Many power users run both.
What are the best Blender Open Data Benchmark alternatives?
For CPU rendering comparisons: Cinebench 2024 (fast, widely cited) and Corona Benchmark (unbiased path tracer, free). For GPU compute: Geekbench 6 GPU covers Metal throughput more broadly. For a full system stress test rather than a rendering-specific score, Prime95 combined with GPU Benchmark by Unigine (Heaven) gives thermal headroom data that a render benchmark alone won't surface. None of these replace Blender Open Data Benchmark if your actual workload is Blender; they are complements, not substitutes.
