Level 1 cache is actually on the CPU chip and isn't really variable... for any given type of chip, it is what it is and isn't something you should need to worry about. I really have no idea why computer manufacturers feel the need to list it.
A modern CPU will typically have an L1 cache of about 64-128 KB per core.
external cache or level 2 or L2 cache
True.
Level 2 cache (L2 cache)
False
true
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).

Cache misses move up the chain (or down the chain, if you want to think of it that way). If the information required is not in your L1 cache, then it checks for it in the L2 cache. If it isn't there either, then you need to go out and grab it from main 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.
The Intel Pentium Pro was the first Intel processor to contain level 2 cache.
