Показать описание
A CPU cache is a smaller faster memory used by the central processing unit (CPU) of a computer to reduce the average time to access memory.The Cache Memory is the Memory which is very nearest to the CPU , all the Recent Instructions are Stored into the Cache Memory. The Cache Memory is attached for storing the input which is given by the user and which is necessary for the CPU to Perform a Task. But the Capacity of the Cache Memory is too low in compare to Memory and Hard Disk.
The following are the deferent levels of Cache Memory.

Level 1 (L1) Cache
It is also called primary or internal cache. It is built directly into the processor chip. It has small capacity from 8 Km to 128 Kb.

Level 2 (L2) Cache
It is slower than L1 cache. Its storage capacity is more, i-e. From 64 Kb to 16 MB. The current processors contain advanced transfer cache on processor chip that is a type of L2 cache. The common size of this cache is from 512 kb to 8 Mb.

Level 3 (L3) Cache
This cache is separate from processor chip on the motherboard. It exists on the computer that uses L2 advanced transfer cache. It is slower than L1 and L2 cache. The personal computer often has up to 8 MB of L3 cache.

Thank you.

I have phenom x4 840 which has L1 64kbytes, L2 512 Kbytes but has no L3 6mb. Does it affect anything ? For instance, if I buy phenom x4 945 which has L3 6mb, Would it be a lot better ?
