The L1 cache speed runs at the same speed as the CPU-central processing unit.
Fast access memory which is inside the actual CPU chip.
l1 cache l2 cache
Usually the register set memory. The L1 cache may be as fast.
The Pentium Pro had both an L1 and an L2 cache on the CPU.
CPUs do have a cache (either L1, L2 or L3), but cache is not exclusively on the CPU.
advanced transfer cache
L2 cache
L1 Cache. And more recently, the L2 cache as well.
Caches are generally defined as L1, L2, and L3. If a CPU has any cache memory at all, it will have at least L1 cache. L1 cache is the fastest, and most expensive, type of cache memory. Usually CPUs will only have a very small amount of L1. L2 is typically larger, less expensive, and slower than L1. L3 is less expensive, larger, and slower than L1 or L2, if present. All three levels of cache memory are magnitudes faster than system memory. Systems withequivalenthardware, including CPUs will identical speeds, will perform better at certain tasks when more cache memory is present, with L1 cache adding the most performance boost.
Usually the size of the L2 cache will be larger than the L1 cache so that if data hit in L 1 cache occurs, it can look for it in L 2 cache.. If data is not in both of the caches, then it goes to the main memory...
