Detailed explanation-1: -L1 or L2 can be significantly faster than L3, though L3 is usually double the speed of DRAM. With multicore processors, each core can have dedicated L1 and L2 cache, but they can share an L3 cache. If an L3 cache references an instruction, it is usually elevated to a higher level of cache.
Detailed explanation-2: -The main difference between L1 L2 and L3 cache is that L1 cache is the fastest cache memory and L3 cache is the slowest cache memory while L2 cache is slower than L1 cache but faster than L3 cache. Cache is a fast memory in the computer. It holds frequently used data by the CPU.
Detailed explanation-3: -This memory is known as the L1, L2, and L3 Cache. The L1 Cache is the fastest (and the smallest) among the three, storing just a few kilobytes of data that can be very quickly given to the CPU for processing. The L2 cache is slightly larger, but also slightly slower than the L1 cache.
