You may be wondering "what is cache?" and what has it got to do with my computer? This article will be an introduction to this common computer term and will clear the air for you if you're a little confused about it all.
Just a heads up though - you don't need to know all the advanced mini details about how computers work, such as knowing about cache memory in detail, to actually just go ahead and build a computer. But it's good to be aware of what certain important computer terms mean, such as cache memory, and have a general overview of how they work so you can become a smarter consumer in the hardware and technology market.
Cache is a type of computer memory, and its release marked one of the most important events in the history of computing. Simply put, cache memory is a small pool of memory that stores information that the CPU is likely to need next. The overall goal is to ensure that your processor has quick access to the next amount of data that it likely needs to make calculations.
All you really need to know is that cache memory is important to your CPU and the more cache your CPU has, the more efficiently and faster it will run. Which means slightly better gaming and application performance for you.
So if you have the chance to pick between two CPUs, go for the one with the higher cache (but note it's not the only factor in choosing a fast CPU).
Most CPUs will have what's called as L1 and L2 cache memory. Some also have an L3 cache. The budget processors out there typically have a low amount of cache in them and is one reason why they are priced low because cache is expensive.
Now you won't need to keep wondering to yourself "what is cache" when you inevitably hear someone mention it around the hardware community.
