which cache memory is more important in processing ,start up and good gaming
L1,L2,L3 Cache memory ?
They all serve different purposes
The L1 cache is accessed on every instruction cycle as part of the instruction pipeline and is broken into separate instruction and data caches. Thus, the design of the L1 cache should be to maximize the hit rate (the probability of the desired instruction address or data address being in the cache) while keeping the cache latency as low as possible. Intel uses an L1 cache with a latency of 3 cycles.
The L2 cache is shared between one or more L1 caches and is often much, much larger. Whereas the L1 cache is designed to maximize the hit rate, the L2 cache is designed to minimize the miss penalty (the delay incurred when an L1 miss happens).
For chips that have L3 caches, the purpose is specific to the design of the chip. For Intel, L3 caches first made their appearance in 4 way multi-processor systems (Pentium 4 Xeon MP processors) in 2002. L3 caches in this sense greatly reduced delays in multi-threaded environments and took a load off the FSB. At the time, L3 caches were still dedicated to each single core processor until Intel Dual-Core Xeon processors became available in 2006. In 2009, L3 caches became a mainstay of the Nehalem microprocessors on desktop and multi-socket server systems.
