How to check Processor Cache Memory Size on Windows 11, 10, 8 and 7?


Before getting into the details you should understand what cache memory really is. Cache is the formal word for temporary memory known as “CPU cache memory.” This chip-based feature of your computer allows you to access information faster than you would if you accessed it through your computer’s main hard drive. If your Windows computer or laptop is equipped with the latest processor or CPU and you want to see whether it is equipped with Cache Memory, this risewindows article is going to be your savior.

A CPU contains many independent caches that store instructions and data. A CPU’s L1, L2, and L3 caches serve as a buffer between RAM and the CPU.

In order to store the most often used information required by the CPU in the Processor Cache, the Processor has its own cache memory. The processor does not have to spend time accessing the most often used data from the main memory (RAM) of the computer as the most frequently used data is immediately available within the Cache.

A computer’s Processor Cache enables faster access to information than its main memory (RAM), resulting in speedier software and data processing. Because Processor Cache Memory is more expensive than RAM, computers use less Processor Cache Memory than RAM.

Processor Cache has three levels, for your information. These are as follows:-

  • L1 Cache: This is the primary cache built into the CPU chip. This form of cache is fast, however it has limited store capacity. Unfortunately, we rarely see these kind of processors with an L1 cache nowadays.
  • L2 Cache: This is a secondary cache that can be incorporated on the processor chip or made available on its own independent chip through a high-speed bus.
  • L3 Cache: L3 Cache processors are intended to serve as a backup for L1 and L2 caches. Although L3 Cache is slower than L1 and L2 Caches, it is faster than RAM and considerably increases L1 and L2 Cache.

The main thing is that the more L2 and L3 cache on your PC, your system will fetch the data faster, resulting in your program will respond quicker and more precisely.

How to Check Processor Cache Memory Size in Windows using Command Prompt?

Use the following to check the processor cache memory size in Windows using Command Prompt:-

Step 1: Go to the Command Prompt on your computer.

To open the Command Prompt window, press the Windows logo + R keys at the same time to enter the Run dialogue box. Then, in the Run box, type cmd and push Enter from the keyboard:-

wmic cpu get L2CacheSize, L3Cachesize

The above command returns the size of the L2 and L3 caches in KB. The processor features a 256 KB L2 cache and a 3072 KB L3 cache, as shown in the above figure.

How to View Processor Cache Memory Size in Windows through Task Manager?

Use the following steps to view or see the process cache memory size:-

Step 1: Open the Task Manager on your system.

Alternatively, you can use the Ctrl + Shift + Esc keys simultaneously on your computer to do so.

Step 2: If the Task Manager opens in compact form, click on the More details button to view it in full mode.

Step 3: Now, click on the Performance tab in the Task Manager window. Then, in the left pane, click on CPU. The sizes of the L1, L2, and L3 caches are listed at the bottom of the right pane.

How to Know Processor Cache Memory Size in Windows using CPU-Z?

Use the following steps to find the processor cache memory size using freeware CPU-Z by performing the following:-

Step 1: Download the CPU-Z freeware utility from the official website.

Step 2: Install it on your computer and then run this tool.

Step 3: In Windows 11 or 10, select the Caches tab to view the specifics of Processor Cache Memory Size. You may use this program to check the cache size on Windows 8 and 7 as well.

That is it.
