CPU & GPU Benchmarks

Run client-side CPU and GPU micro-benchmarks in your browser. Results measure relative performance and depend on browser, device, and power settings.

CPU Benchmark (Matrix Multiply)

GPU Benchmark (WebGL Render)


        

Notes

  • CPU benchmark uses JavaScript matrix multiplication to estimate GFLOPS.
  • GPU benchmark uses WebGL fragment shader complexity and measures FPS.
  • Results are not absolute; use as relative comparisons between devices/browsers.

How to Use the Online Benchmarks

1 Choose Benchmark Tests

Select Single-Thread CPU test, Multi-Thread Worker test, Memory Allocation test, or GPU Canvas 2D/WebGL rendering test.

2 Initiate Performance Run

Click "Run Benchmark" to execute mathematical stress algorithms and frame rendering loops.

3 Monitor Execution Progress

Observe real-time operations per second (OPS), prime number sieves, matrix multiplications, and FPS gauges.

4 Review Score & System Specs

Inspect your overall performance score, CPU core count, device memory estimate, and compare against reference desktop and mobile scores.

Frequently Asked Questions

Common questions about using this free online benchmarks.

What algorithms are used in the CPU benchmark? โ–พ
The CPU test uses compute-intensive mathematical workloads including Sieve of Eratosthenes prime generation, SHA-256 cryptographic hashing iterations, and floating-point matrix transformations.
How does the Multi-Thread benchmark measure multicore performance? โ–พ
It spawns hardware-concurrent HTML5 Web Workers matching your CPU's logical thread count (`navigator.hardwareConcurrency`), measuring parallel execution throughput.
What does the GPU Canvas test evaluate? โ–พ
The GPU test renders thousands of moving particle sprites with physics and lighting on HTML5 Canvas and WebGL, evaluating your hardware graphics acceleration and frame rate stability.
Can I use this benchmark to compare browser performance? โ–พ
Yes. Running the identical test in Chrome, Firefox, Edge, and Safari reveals how efficiently each browser's JavaScript JIT compiler (V8, SpiderMonkey, JavaScriptCore) executes compute workloads.
