There are levels of cache memory in the intel i7 processor.

There are 3 levels of cache memory in the intel i7 processor.

Explanation:

   Cache memory is divided into some levels, known as L1, L2, and L3 (L stands for Level). They relate to the proximity of cache to processor execution units. The closer it is to the processor execution unit, the lower its number.

    Thus, the L1 cache is as close as possible. L2 is a little farther and L3 is even farther. Whenever the processor search unit needs new data or instruction, it initially looks in cache L1. If not, go to L2 and then L3. If the information is not at any of the cache levels, it will have to go to RAM.

  A peculiarity about the levels is that L1 is divided into instruction memory and data memory. With this, the processor goes straight to instruction memory if it is looking for an instruction, or goes straight to data memory if it is looking for data. This further speeds up the search processor.
