But how does cache memory work and how does it tie in with thebest processors?
These are all vital questions that will be answered in the explainer below.
Cache memory explained
1.
What is cache memory?
The actual jot down of memory used for cache is called high-speed static random access memory (SRAM).
Why is cache memory important?
Cache is important because of its speed.
However, cache also has two drawbacks in that it provides less storage and is more expensive.
Types of cache memory
Cache memory is categorized into three levels, each larger and slower than the last.
L1 cache is extremely small yet fast and is usually built into the processor as CPU cache.
This is where recent instructions and data that are likely to be requested are stored.
L3 cache is specialized memory that improves the performance of L1 and L2.
Though L1 and L2 are much faster than L3, L3 is twice as fast as DRAM.
RAM is much less expensive and has more space for storage.
Final thoughts
Cache memory is a vital part of a PC’s performance and efficiency.
It’s best to worry about overall performance rather than just cache.
These will boost your PC’s performance far more than an increase in cache.
