Computer processors have advanced quite a bit in recent years.
Transistors get smaller every year, and advancements are hitting a point where Moore's Law is becoming redundant.
When it comes to processors, it's not just the
transistors and frequencies that count but also the cache.
You might have heard about cache memory when CPUs (Central Processing Units) are being discussed.
However, we don't pay enough attention to these CPU cache memory numbers, nor are they the primary highlight of CPU advertisements.
What exactly is CPU cache?
Why are there L1, L2, and L3 caches?
Here's what you need to know and how they work.
