What Is Cache Memory L1 L2 L3 Cpu Cache Explained Mem Vrogue Co The main differences between l1, l2, and l3 cache memory are are capacity and transfer speed. l1 is low capacity but extremely fast, l2 is slower but has more storage space, and l3 is the slowest of the three but also usually has the biggest storage capacity. modern computer processors all use a multi level cache memory system that allows data. A cpu cache is a small, fast memory area built into a cpu (central processing unit) or located on the processor's die. the cpu cache stores frequently used data and instructions from the main memory to reduce the number of times the cpu has to access the main memory for this information. this can greatly improve system performance, as accessing.

L1 vs l2 vs l3 cache. current cpus implement 3 levels of cpu cache to maximize performance. this allows them to hit the sweet spot for cache size, latency, and hit rate. l1 – fastest but smallest, per core (128 kb – 2 mb total) l2 – medium latency and capacity, can be per core or shared (256 kb – 32 mb total) l3 – slowest but largest. Below, we can see a single core in amd's zen 2 architecture: the 32 kb level 1 data and instruction caches in white, the 512 kb level 2 in yellow, and an enormous 4 mb block of l3 cache in red. L2 cache, or level 2 cache, is the secondary cpu cache. it’s slower than level 1 cache, but still pretty fast, and offers a significant bump in memory capacity. depending on if your cpu has an l3 cache or not, l2 cache will either be distributed across individual cpu cores or shared by all cpu cores. until very recently, intel cpus only used.
