The Level 3 (L3) cache has the highest latency. The CPU cache is memory that is used to decrease the time that it takes the CPU to access data. Because the data is cached, it can be accessed more quickly. The CPU cache is often found directly on the CPU or built into the CPU. The L3 cache is usually larger than the L1 and L2 cache, but it is searched last. The CPU searches for data in the following order: L1 cache, L2 cache, L3 cache, RAM.
Not the same.
delay to access the data in cache in context of processor's speed. Time to access the requested data in cache , at that time processor have to wait .. is called cache latency.
Primary cache memory, often referred to as CPU cache, is typically measured in terms of capacity (e.g., kilobytes or megabytes) and speed (latency). The cache hierarchy includes levels like L1, L2, and L3, with L1 being the fastest and smallest, while L3 is larger but slower. Performance can also be assessed by metrics such as hit rate (the percentage of cache accesses that are successful) and miss rate. These measurements help evaluate the effectiveness of the cache in reducing access times to main memory.
CPUs do have a cache (either L1, L2 or L3), but cache is not exclusively on the CPU.
L3 Cache
miss latency is the time (in cycles) the CPU waits when a miss happen in the cache. (the time needed to bring the data from the main memory to the cache).
L3 cache
L3 cache
L1, L2, and L3
L3 cache is located on the motherboard or in CPU housing.Hope this help.
Level 3 (L3) cache memory is generally slower than Level 1 (L1) and Level 2 (L2) caches, but it is still faster than main RAM. L3 cache serves as a larger storage area for frequently accessed data and instructions, helping to reduce latency when the CPU accesses memory. While it may not be as fast as L1 or L2 caches, its larger size allows it to improve overall performance by holding more data closer to the CPU.
