The Cache & Memory Benchmark is an advanced tool designed to evaluate the performance of your system's CPU caches and RAM. It provides detailed metrics on two crucial aspects: bandwidth and latency. Bandwidth measures the rate at which data is transferred between the CPU and memory, indicating the efficiency of data throughput. Latency, on the other hand, measures the time delay in accessing data, reflecting the responsiveness of the memory system.



Granular Control and Customization

AIDA64 allows for precise and customizable benchmarking tailored to your specific needs. You can select which tests to run by simply double-clicking within the grid. Here's how it works:

  • Double-clicking a memory type (such as L1 Cache, L2 Cache) will perform read, write, copy, and latency benchmarks for that particular cache level.
  • Double-clicking an operation (such as Read, Write, Copy, Latency) will conduct that operation across all memory types, including L1 Cache, L2 Cache, and RAM.
  • Double-clicking a specific cell will execute only the selected benchmark (for example, L1 Cache Read).

These options provide you with the flexibility to focus on the exact performance metrics you need.

Simplified Benchmark Selection

For a quick assessment, right-click the "Start Benchmark" button to open a context menu. This menu lets you choose between running all benchmarks, focusing only on memory benchmarks, or isolating cache benchmarks. This feature allows you to easily select the level of detail needed for your analysis.


By effectively utilizing the Cache & Memory Benchmark, you can identify potential bottlenecks in your system's memory and cache performance, enabling you to optimize settings for enhanced overall performance.
