Cache is very fast memory that is located in the processor chip. Cache is located in three levels: L1 being the fastest, L2 and L3 being the slowest.
- L1 is usually located on the processor die itself but is limited in the amount of space that can be used.
- L2 is more cost effective but a little slower because it is farther out from the processor die.
- L3 can be located either on the CPU chip or the motherboard and is larger than L2 cache.
