What is the impact of cache on latency in computing?

What is the impact of cache on latency in computing?

Cache significantly reduces latency by storing frequently accessed data closer to the CPU, minimizing access time.

Can you explain how cache levels (L1, L2, L3) affect performance?

Sure! L1 is the fastest and smallest, L2 is larger but slower, and L3 is even larger and shared among cores, impacting overall speed.

What happens if the cache is full?

When the cache is full, the system must evict some data to make room for new data, which can increase latency.

How does cache size influence latency?

Larger cache sizes can store more data, reducing the need to access slower memory, thus lowering latency.

Are there any downsides to having a large cache?

Yes, larger caches can lead to increased complexity and longer access times if not managed properly, potentially negating benefits.
