On-Package L2 cache (discrete L2 cache) is on a separate microchip within the processor housing, while Advanced Transfer Cache (ATC) is located directly on the same die as the processor core.
An L2 cache is built directly on the processor chip as an advanced transfer cache. Data is transmitted via the front side bus.
An Advanced Transfer cache allows for the L2 cache to rest completely inside the core processor of a computer. It features a 256-bit wide bus.
The discrete L2 is located within the processor housing, on a separate chip. The Advanced Transfer Cache is located directly on the processor die itself.

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.
Level 2 (L2) cache is built onto the processor. On Older slot-mounted processors, L2 cache was external to the processor die, and ran at slower speeds than the processor. on socketed processors, L2 cache is built onto the processor. If the processor does not find the desired memory locations in L1 cache, it checks L2 cache next. However Processors with larger L2 caches perform most tasks much more quickly than processors that have smaller L2 caches for two reasons. Cache memory is faster than main memory and the processor checks cache memory for needed information before checking main memory.
