CPU Benchmark

CPU Benchmark - Test Your Processor Performance

A comprehensive online CPU benchmarking tool that tests your processor's performance across multiple workloads. Run various tests including prime number calculations, sorting algorithms, matrix operations, and floating-point computations to measure your CPU's speed and multi-core performance. Compare results and identify performance bottlenecks.

How does CPU benchmarking work?

CPU benchmarking measures processor performance by running standardized computational tasks:

1. Prime Numbers: Tests integer calculations and loops
2. Sorting: Evaluates algorithm efficiency and cache performance
3. Fibonacci: Measures recursive function performance
4. Matrix Operations: Tests mathematical computation speed
5. Hash Calculations: Evaluates string processing
6. Floating Point: Tests decimal number calculations

Each test runs independently and is timed. The score is calculated based on operations per second, with higher scores indicating better performance.

What factors affect CPU benchmark scores?

Several factors influence benchmark results:

- CPU Clock Speed: Higher GHz = faster calculations
- Number of Cores: More cores help with parallel tasks
- CPU Architecture: Newer designs are more efficient
- Browser Performance: JavaScript engine optimization
- Background Processes: Other apps consuming CPU
- Thermal Throttling: Overheating reduces performance
- Power Settings: Battery saver mode slows CPU
- Operating System: Different OS have different overhead

For accurate results, close other applications and ensure your device is plugged in (for laptops).

Why test CPU performance in browser?

Browser-based CPU benchmarks offer several advantages:

- No Installation: Run tests immediately without downloads
- Cross-Platform: Works on Windows, Mac, Linux, mobile
- Safe: Runs in sandbox, can't harm your system
- Accessible: Test any device with a web browser
- Quick: Get results in seconds
- Shareable: Easy to compare results with others

While not as comprehensive as native benchmarks like Cinebench or Geekbench, browser tests provide a good indication of relative CPU performance, especially for web-based workloads.

How to interpret benchmark scores?

Understanding your benchmark results:

- Higher Score = Better Performance (more operations/second)
- Lower Time = Faster Completion
- Overall Score: Average of all test scores

Typical scores by CPU tier:
- High-End Desktop (i9, Ryzen 9): 8,000-15,000+
- Mid-Range Desktop (i5, Ryzen 5): 4,000-8,000
- Laptop CPUs: 2,000-6,000
- Mobile/Tablet: 500-3,000

Note: Scores vary by browser and system load. Run multiple tests for consistency.

What is multi-core performance?

Modern CPUs have multiple cores that can work simultaneously:

- Single-Core: One task at a time
- Multi-Core: Multiple tasks simultaneously

This benchmark uses JavaScript Web Workers to test multi-threaded performance, simulating how CPUs handle parallel workloads.

More cores help with:
- Video rendering
- 3D modeling
- Compiling code
- Running multiple apps
- Gaming (modern titles)

The benchmark shows how well your CPU handles concurrent operations, which is crucial for multitasking and professional workloads.

Why are my scores lower than expected?

Several reasons can cause lower scores:

1. Background Apps: Close other programs
2. Browser Throttling: Try a different browser
3. Power Saving Mode: Switch to high-performance mode
4. Thermal Throttling: Ensure good cooling
5. Old Browser: Update to latest version
6. Mobile Device: Phones score lower than desktops
7. Virtual Machine: VMs have performance overhead
8. Browser Extensions: Disable unnecessary extensions

For best results:
- Close all other tabs and applications
- Plug in laptop (don't run on battery)
- Ensure good ventilation
- Use latest Chrome, Firefox, or Edge
- Wait for CPU to cool between tests

How accurate is browser-based benchmarking?

Browser benchmarks are reasonably accurate for:

- Relative Comparisons: Comparing CPUs side-by-side
- Web Performance: How fast web apps will run
- JavaScript Workloads: Node.js, web development
- Quick Diagnostics: Identifying performance issues

Limitations:
- Browser overhead affects scores
- Single-threaded in some tests
- No direct hardware access
- Affected by JavaScript engine differences

For professional CPU testing, use native tools like:
- Cinebench R23
- Geekbench 6
- CPU-Z
- PassMark

But for quick, free, no-install testing, browser benchmarks provide valuable insights.

Can I benchmark mobile CPUs?

Yes! This tool works on mobile devices:

- Smartphones (iOS, Android)
- Tablets (iPad, Android tablets)
- Chromebooks
- Any device with a modern browser

Mobile CPU considerations:
- Scores will be lower than desktops
- Thermal throttling is more aggressive
- Background apps have bigger impact
- Battery mode significantly affects performance

For mobile testing:
1. Close all background apps
2. Ensure device is not overheating
3. Use landscape mode for tablets
4. Plug in for best performance
5. Use latest Safari (iOS) or Chrome (Android)

Mobile CPUs are optimized for efficiency over raw performance, so lower scores are normal.
