advanced transfer cache
L1 cache
L1 Cache
An L2 cache is built directly on the processor chip as an advanced transfer cache. Data is transmitted via the front side bus.
L1 Cache
Internal Cache
L2 cache
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.
L2 cache. Today's processors all have some memory on the processor chip (called a die). Memory on the processor die is called Level 1 cache (L1 cache). Memory in the processor package, but not on the processor die, is called Level 2 cache (L2 cache). Some processors use a third cache farther from the processor core, but still in the processor package, which is called Level 3 cache (L3 cache).
It is integrated with Processor. Also called Cache Memory.
logical cache is what computer companies call L1, L2, and L3 cache. It is smart memory on the chip or processor that remembers what the processor has ask for the last 10 to 100 processes.
It is integrated with Processor itself. Also called Cache Memory.
; L3 Cache (Level 3 Cache) This type of cache is becoming more prevalent as microprocessor manufacturers ship more processors with L1 and L2 cache built into the processor. L3 cache is then the extra cache that sits on the motherboard between the processor and main memory, since the processor already contains L1 and L2 cache. Some processors are starting to ship with L3 cache built-in as well to speed up memory operations further. In those cases the L3 cache often sits on a separate area of the die, not built directly into the chip core.
short answer : cache chip is more expensive than ram
