What Does Processor Cache Do?

[piggykid1]

What does cache do on a processor and what are the benefits of having a high mb cache processor do?

[Tea1337]

Cache is like RAM just for the processor, it can access it directly and speeds up the machine, the more the better.

[Izaya Orihara]

It's flash storage for the CPU. The same as ram for the pc.

[Glenwing]

It serves the same function as RAM, but it's directly on the CPU die so it is even faster access and lower latency than RAM.

I belive, the more you have it, it helps with memory intensive tasks and distributing tasks between cores.

Ram buffer to CPU..?

[Faa]

Cache is just memory, it's about how you would use it. You'd be better using this for most frequent instructions rather than the ram.

[Thunderjolt]

It's basically a tiny bit of RAM for things that your CPU uses a lot. By storing it on the CPU cache the CPU doesn't need to go to the RAM and get it from there. Also CPU cache runs at basically the same speed as your processor.

It stores tiny commonly used bits and pieces of data. So the processor doesn't have to access the hard drive or memory for that information on a reoccurring basis. Instead its stored locally which is blazing fast even compared to system memory.
