Memory Speed Test - Test Your RAM Performance

A comprehensive online memory speed testing tool that measures RAM performance through various operations. Run tests for array operations, object allocation, string manipulation, typed arrays, and memory allocation to evaluate your system's memory speed and efficiency.

How does memory speed testing work?

Memory speed testing measures RAM performance by executing various operations:

1. Array Operations: Tests read/write speed with standard arrays
2. Object Allocation: Measures object creation and modification speed
3. String Manipulation: Evaluates string operation performance
4. Typed Arrays: Tests binary data handling with typed arrays
5. Memory Allocation: Measures large memory allocation efficiency

Each test runs for a set duration and calculates operations per second, with higher values indicating better memory performance.

What factors affect memory speed?

Several factors influence memory test results:

- RAM Amount: More RAM allows larger operations
- RAM Speed: Higher MHz = faster data access
- RAM Type: DDR5 > DDR4 > DDR3
- CPU Cache: L1/L2/L3 cache affects memory access
- Memory Channels: Dual/quad channel increases bandwidth
- Browser Limitations: JavaScript heap size limits
- Background Processes: Other apps consuming RAM
- Operating System: Memory management efficiency

For accurate results, close background applications and ensure sufficient available RAM.

What is a good memory speed score?

Understanding your memory speed results:

- Higher Operations/Second = Better Performance
- Lower Time = Faster Completion

Typical scores by system tier:
- High-End Desktop (32GB+ DDR5): 50-100+ ops/s
- Mid-Range Desktop (16GB DDR4): 30-50 ops/s
- Budget Desktop (8GB DDR4): 15-30 ops/s
- Laptops: 10-40 ops/s (varies widely)
- Mobile/Tablets: 5-15 ops/s

Note: Scores vary significantly by browser and JavaScript engine optimization.

Why test memory in browser?

Browser-based memory tests offer advantages:

- No Installation: Test immediately without downloads
- Cross-Platform: Works on any OS with a browser
- Safe: Runs in sandbox, can't damage system
- Quick Diagnostics: Identify memory bottlenecks fast
- Web Performance: See how web apps will perform

While not as comprehensive as native tools like MemTest86 or AIDA64, browser tests provide valuable insights into JavaScript memory performance, which matters for web applications, Node.js, and browser-based workloads.
