Intel Cache Hierarchy

Intel's cache hierarchy refers to the organization of memory within Intel processors, designed to speed up data access for CPU operations. It consists of multiple layers of caches: L1, L2, and L3. The L1 cache is the smallest and fastest, directly accessible by the CPU, providing quick access to frequently used data. L2 is larger but slightly slower, and L3 is even larger and shared among cores. This tiered system reduces the time it takes for the CPU to retrieve data, enhancing overall performance by keeping the most relevant information close at hand.
