75 views

L1 cache is faster. It is the smallest and closest to the CPU core, offering the shortest access time. In contrast, L3 cache is larger but slower, designed to serve multiple cores more efficiently.

FAQs & Answers

  1. What is L1 cache? L1 cache is a small, fast memory located closest to the CPU, providing rapid access to frequently used data.
  2. What is L3 cache? L3 cache is larger than L1 and L2 caches and is designed to support multiple CPU cores, but is slower in access time.
  3. How does cache size affect performance? Generally, larger cache sizes can store more data, which can lead to improved performance, but access speed decreases with size.
  4. Why is L1 cache faster than L3 cache? L1 cache is smaller and located directly next to the CPU core, resulting in quicker access times compared to L3 cache.
