What is the name of the memory cache that is closest to the processor die but is not housed on the die?

Answer 1

Level 2 cache (L2 cache).

There is no specific name for memory caches based on physical location. CPU memory caches are named for function, not location.

As such, there are Level 1, Level 2, and Level 3 caches (and, theoretically, there's nothing preventing Levels 4 and up from being created). Each can be located anywhere (on-die, in-package, off-chip, etc.) depending on the design of the CPU and motherboard.

Modern x86 chips from Intel and AMD include up to L3 cache on-die.

Answer 3

Cache (English name Cache), that cache is located on the CPU and main memory DRAM (that is, memory) between the smaller but high speed memory (in fact, hard drive, recorder cache are also a reason) . The CPU cache in two, is an internal cache, also known as a cache (L1 Cache): closed in CPU chip's internal cache for temporary storage when the operation part CPU instructions and data access speed and the main CPU the same frequency. Larger L1 cache, CPU work and access the L2 cache and slower memory to exchange data between the fewer the number, the relative speed of the computer's operation can be improved; external cache, also called secondary data cache (L2 Cache): CPU external cache, the processor's L2 Cache is now and the CPU running at the same frequency (formerly P2 P3 secondary cache runs at half the CPU frequency is equivalent to the next).

Answer 4

There is no specific name for memory caches based on physical location. CPU memory caches are named for function, not location.

As such, there are Level 1, Level 2, and Level 3 caches (and, theoretically, there's nothing preventing Levels 4 and up from being created).

In modern CPU designs, virtually all Level 1 and Level 2 caches are now located on-die, and the vast majority of L3 caches are also on-die. Some designs do have the L3 cache located in the CPU package, not on the die.

In the past, it was not uncommon to find L2 and L3 caches located on the motherboard itself, not even in the CPU package.
