No downloads. No installation. Choose a plan, run the benchmark, and get a detailed performance report in under 60 seconds.
GPUHammer uses WebGPU — the modern graphics API built into Chromium-based browsers — to run a real, production-quality stress test on your GPU. No binaries, no telemetry, no waiting.
Visit gpuhammer.forgebox.cc on any Chromium-based browser (Chrome, Edge, Arc, Brave). WebGPU is built in — nothing to install or configure.
→Click "Run Benchmark" and let WebGPU stress-test your GPU with real compute and rendering workloads. The test takes under 60 seconds on most hardware.
→Get your score instantly. See how you rank against every GPU in our database — from integrated laptop chips to flagship discrete cards. Share your result with a single link.
GPUHammer isn't a toy — it's a real GPU stress test powered by WebGPU compute shaders. We measure what actually matters for GPU performance.
Runs entirely in your browser tab using WebGPU. No .exe, no install wizard, no 500 MB download. Just click and benchmark.
Chrome, Edge, Brave, Arc — any Chromium-based browser with WebGPU enabled. Full support on Windows, macOS, and ChromeOS.
WebGPU is the successor to WebGL — a modern, low-level GPU API giving web apps direct access to GPU compute and rendering pipelines.
See compute throughput, memory bandwidth, fill rate, and composite scores. Not just one number — a full breakdown of your GPU's capabilities.
Fast, accurate, and repeatable. The full benchmark suite completes in under a minute on modern hardware, so you can iterate quickly.
Every benchmark run gets a unique, shareable URL. Share your score on Reddit, Twitter, or Discord with a direct comparison link.
Run one benchmark instantly at no cost. Upgrade to One-Time Analysis for detailed recommendations, or go Pro for unlimited runs and full features.
Try it once. Get your GPU score. No credit card required.
One purchase, one detailed report with actionable recommendations.
Unlimited runs for power users who track GPU performance over time.
All plans run entirely in your browser via WebGPU. No downloads, no installation. Free tier gives you a real GPU score — upgrade only when you want recommendations and deeper analysis.
