No 8 GB download
Geekbench, Cinebench, 3DMark, PassMark all need 500 MB–8 GB and admin rights. Useless on corporate networks, schools, shared computers.
"0 MB to test."

No fake precision
We tell you when our number is approximate. RAM is browser-sandboxed. We say so loudly instead of pretending our number is gospel.
"We say what we can't measure."
" Every formula. Every constant. Every weight. If you find a flaw, file an issue. We ship the patch the same week. "

Compare a permalink.
Paste any 9bench result URL or 8-char hash to view the full breakdown. Every result includes CPU, GPU, and RAM scores, global percentile ranking, and a shareable link. You can also compare two results side-by-side or check the global leaderboard to see how your hardware stacks up.
RAM disclaimer: browser sandbox limits absolute throughput.
Treat the RAM score as comparative, not absolute. We say so out loud.

9bench is a free, open-source browser-based hardware benchmark that tests your CPU, GPU, and RAM speed in about 15 seconds — no download, no installation, no account required. The entire benchmark runs locally in your browser using WebGPU compute shaders, WebAssembly, Web Workers, and the Web Crypto API. Results include a global percentile ranking against all submitted scores.

How does the 9bench benchmark work?
- GPU compute: A 1024×1024 floating-point matrix multiplication runs on your GPU via WebGPU compute shaders, measuring GFLOPS (billions of floating-point operations per second).
- CPU single + multi-core: SHA-256 hash chains via the Web Crypto API measure single-thread performance. Parallel Web Workers test multi-core scaling across all available cores.
- RAM bandwidth: Sequential and random-access patterns on a 256 MB Float32Array measure read/write throughput (GB/s) and latency (nanoseconds).
The overall score uses a weighted geometric mean:
overall = exp(0.35 × ln(GPU) + 0.45 × ln(CPU_multi) + 0.20 × ln(RAM))This means 35% GPU, 45% CPU multi-core, 20% RAM. A single weak component cannot be masked by strong ones — the geometric mean penalizes imbalance. Every formula is documented on the methodology page.
9bench vs Geekbench vs UserBenchmark vs Cinebench
| Feature | 9bench | Geekbench 6 | UserBenchmark | Cinebench |
|---|---|---|---|---|
| Price | Free | Free / $9.99 Pro | Free | Free |
| Download required | No (browser) | 500 MB | 80 MB (.exe) | 800 MB |
| Test duration | ~15 seconds | 5-10 minutes | 2-3 minutes | 10+ minutes |
| Works on locked PCs | Yes | No (admin) | No (admin) | No (admin) |
| Open methodology | Yes (MIT) | Partial | No | No |
| Vendor bias | None | None | Documented anti-AMD | None |
| GPU + CPU + RAM | All three | CPU + GPU | All three | CPU only |
| Mobile support | iOS, Android | iOS, Android | Windows only | macOS, Windows |
On the other hand, native benchmarks like Geekbench and Cinebench are more accurate for absolute peak measurement. If you need precise single-core IPC numbers for a hardware review, you should use Geekbench. If you need instant, zero-friction relative comparison across machines — try 9bench. The two approaches complement each other.
What are the 9bench score brackets?
Scores are calibrated to hardware. Our research across submitted results shows that the median score is approximately 1200 (mid-range category), with the top 5% exceeding 4000. A single weak component cannot be masked by strong ones because the composite uses a geometric mean.
| Tier | Score range | Typical hardware (2026) |
|---|---|---|
| S-tier (top 5%) | 4000+ | Apple M5 Max, Ryzen 9 9950X3D + RTX 5090 |
| A-tier | 2500–4000 | Apple M4 Pro, Ryzen 9 7950X + RTX 4080 |
| Strong mainstream | 1700–2500 | Apple M3 Pro, Ryzen 7 7800X3D + RTX 4070 |
| Mid-range | 1000–1700 | Ryzen 7 5800X, mid-tier 2024 laptops |
| Mainstream / older | 500–1000 | Older laptops, integrated GPUs |
| Office / Chromebook | <500 | Chromebooks, older office laptops |
For example, a 2024 MacBook Pro M3 Pro typically scores around 2100 in 9bench — placing it firmly in the "Strong mainstream" bracket. A budget Chromebook with an integrated GPU usually lands below 400.
Why was UserBenchmark banned?
In 2019, r/hardware and r/pcmasterrace banned UserBenchmark.com for documented anti-AMD bias (source). Their scoring formula systematically over-weights single-core Intel performance, producing rankings that independent reviewers flagged as misleading.
9bench was built as a transparent alternative: every formula and weight is published on the methodology page and in the MIT-licensed source code. No vendor has paid or can pay to influence the scoring.
Which browsers support 9bench?
9bench requires WebGPU for GPU benchmarking, as defined in the W3C WebGPU specification. Supported browsers:
- Chrome 113+ and Edge 113+ — full WebGPU support since
- Firefox 147+ — stable WebGPU since early
- Safari 26+ — macOS Tahoe, iOS 26, iPadOS 26, visionOS 26
On older browsers without WebGPU, CPU and RAM tests still run — only the GPU score shows "0". Try updating your browser if you see a WebGPU error.
Tips for accurate benchmark results
You should follow these steps to get the most reliable scores from 9bench:
- Close background apps — browser tabs, video calls, and downloads compete for CPU and RAM bandwidth, which can reduce your scores by 10–30%.
- Plug in your laptop — battery-saver mode throttles clock speeds by 20–40%, which directly lowers benchmark results.
- Run 2–3 times — pick the highest score. Variance of ±5–10% between runs is normal; ±30% or more indicates background contention.
- Use Chrome or Edge for the most accurate GPU scores — their WebGPU implementations are the most mature as of .
Verdict: who should use 9bench?
Use 9bench if you want to quickly compare machines (for example, "is this 5-year-old laptop worth upgrading?"), test hardware in corporate environments where installing software is restricted, or share benchmark results via a permalink without creating an account.
Use Geekbench if you need absolute peak scores for a hardware review. Use Cinebench for sustained multi-core rendering performance numbers. Use 3DMark for gaming-specific GPU benchmarks. 9bench is the best option for instant, zero-friction, vendor-neutral browser-based benchmarking — and it complements native tools rather than replacing them.
Frequently asked questions
Is 9bench accurate?
Within 3-10% of native benchmarks for CPU and GPU compute. RAM scores are browser-sandboxed (30-50% of native). For absolute peak measurement use Geekbench or Cinebench. For instant relative comparison across machines, 9bench is purpose-built.
How does 9bench compare to UserBenchmark?
UserBenchmark is community-banned by r/hardware and r/pcmasterrace for documented anti-AMD bias. 9bench takes zero vendor money, publishes all scoring formulas openly, and is MIT-licensed open source.
Does 9bench work on iPhone, iPad, and Android?
Yes. Safari 26+ on iOS/iPadOS supports WebGPU compute shaders. Chrome 113+ on Android does too. Older devices fall back to CPU + RAM tests with a clear notice.
What data does 9bench collect?
During the test: nothing leaves your browser. Score submission is opt-in. Submitted data is anonymous: benchmark numbers, GPU adapter name if visible, CPU core count, shortened user-agent. No IP, no cookies, no fingerprints.
Why is it free?
9bench runs entirely in your browser — server cost is near zero (Cloudflare D1 free tier). No tracking, no ads, no premium upsell. The core benchmark stays free forever.
How long does the benchmark take?
About 15 seconds for the full CPU + GPU + RAM test. No download or installation required — just open the page and click Start.
