L2 Cache vs. L3 Cache

What's the Difference?

L2 cache and L3 cache are both types of cache memory found in computer systems, but they differ in terms of their size, proximity to the CPU, and their role in improving system performance. L2 cache, also known as secondary cache, is located closer to the CPU than L3 cache and is smaller in size. It acts as a buffer between the CPU and the main memory, storing frequently accessed data and instructions to reduce the time it takes for the CPU to retrieve them. On the other hand, L3 cache, also known as tertiary cache, is larger in size and is located further away from the CPU, often shared among multiple cores or processors. It serves as a backup to the L2 cache, providing additional storage for frequently accessed data and instructions. While L2 cache offers faster access times due to its proximity to the CPU, L3 cache provides a larger storage capacity, making it beneficial for multi-core processors or systems with high data demands.
