Description

Need information about cache size of L1, L2, and L3 for Intel® Processor.

Resolution

To find the total size of the L1, L2, or L3 cache for Intel® Processor, follow the steps below:

  1. Download  the Intel® Processor Identification Utility.
  2. Launch the utility.
  3. View L1 Cache, L2 Cache, and L3 Cache sizes, located under CPU Information section.

To find details about the L1, data cache and Instruction cache, and L2, click the arrow in the CPU Information section (this feature is available only for Intel® 12th Generation and newer processors with hybrid architecture).

To find out if your Intel® Processor supports hybrid architecture, check if the processor has Efficient-cores and Performance-cores. Refer to What Is Performance Hybrid Architecture for more details.

Here is an example:
