L3 cache

Level 3 cache is the third-fastest cache memory available to a CPU. It usually consists of SRAM chips located on the motherboard. The "L3" indicates that the CPU attempts to access this cache after accessing the L1 and L2 cache. Level 3 cache is now the name for the extra cache built into motherboards between the microprocessor and the main memory.
