L3 cache is located on the motherboard or in CPU housing.
Hope this help.
in the CPU

l1 cache l2 cache
The L1 cache speed runs at the same speed as the CPU-central processing unit.
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
L1 cache is located as close as possible to the actual CPU using it. (if the CPU is in a Microprocessor L1 cache will always be on the same IC chip as the Microprocessor so that external pins of the device will not be needed to reach it)Unlike higher levels (L2, L3, L4, etc.) of cache L1 cache is usually split into independent data and instruction caches.L1 data cache stores recently used data, permitting quick reaccess if that data is used repeatedly.L1 instruction cache stores recently used instructions, permitting quick reaccess if those instructions are used repeatedly.L1 cache is consulted first by the CPU when it needs data or instructions to speed up operation when data or instructions are used repeatedly.If the data or instruction is not found in L1 cache then L2 cache is consulted, etc. until it has been shown that the data or instruction needed is not in any Level of cache, at which time main RAM (or even Virtual Memory on disk) is accessed.
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...
ram --- Wrong. RAM actually CAN be upgraded without touching the processor. L1, L2, and L3 cache are physically located INSIDE of the processor, so they obviously cannot be changed or upgraded without replacing the processor itself.
