Question: what is the difference between l1 l2 and l3 cache memory?
Answer: L1 cache, or primary cache, is extremely fast but relatively small, and is usually embedded in the processor chip as CPU cache. ... Level 3 (L3) cache is specialized memory developed to improve the performance of L1 and L2. L1 or L2 can be significantly faster than L3, though L3 is usually double the speed of DRAM.
