L1 vs L2 Cache
Summary: Difference Between L1 and L2 Cache is that L1 cache is built directly in the processor chip. L1 cache usually has a very small capacity, ranging from 8 KB to 128 KB. While L2 cache is slightly slower than L1 cache but has a much larger capacity, ranging from 64 KB to 16 MB.
Most of today’s computers improve processing times with cache (pronounced cash). Two types of cache are memory cache and disk cache. This chapter discusses memory cache. Memory cache helps speed the processes of the computer because it stores frequently used instructions and data. Most personal computers today have at least two types of memory cache: L1 cache and L2 cache.
L1 Cache
L1 cache is built directly in the processor chip. L1 cache usually has a very small capacity, ranging from 8 KB to 128 KB. L1 and L2 both are levels in cache memory. L1 usually built on processor chip itself. L1 Cache is totally shared between two cores.
L2 Cache
L2 cache is slightly slower than L1 cache but has a much larger capacity, ranging from 64 KB to 16 MB. Current processors include advanced transfer cache, a type of L2 cache built directly on the processor chip. Proces sors that use advanced transfer cache perform at much faster rates than those that do not use it. Personal computers today typically have from 512 KB to 12 MB of advanced transfer cache.
