What's do cores do in a cpu

[Cake.]

I use my laptop to play a bunch of games on but when not ever I go to propitys on my pc in flies explorer it says my cpu speed is 1.8ghz and I've got 4 cores does it mean I have 1.8 x 4 or do y cores do something else if so plese explane ps I'm running Windows 10 if it helps

all desktop computers use to have single core CPU. For extra power to run multiple program threads servers use to have between 1 and 4 CPU sockets. When die size became small enough AMD was able to combine the previous server technology into one die thereby making the first desktop 2-core CPU. What it means to you is you can operate more than one program at a time without noticeable slowdown

Each core processes instructions.

Most programs initially were single threaded -only using single cores cos thats all existed way back when..

 

The faster the core of a specific "cpu generation" will process instructions faster.

 

Multiple cores will each process data independently.

You need to program multicore usage.

So you then can get 2-4 threads for your 2-4 core cpu to be used.

If a single threaded program runs on a multicore cpu, you'll find its only using a single core (25% seen in task manager of a quadcore cpu) for that thread.

 

Each cpu generations instructions per clock cycle usually gets faster as well.

basically the rate at which CPUs can get faster slowed down drastically because of the heat faster CPUs create. So to make CPUs better, they instead switched to adding cores. So instead of doing 1 thing quickly, it can do 2 things quickly with 2 cores or 4 thing quickly with 4 cores. The way this is most beneficial for gaming is sometimes you don't close every program before opening your game and also something you stream your gaming and then you have your voice chat open, and you have your web browser will open, and then window is running an updater in the background, and so you have a lot of things actually running in addition to the game, and when you have a high number of cores, this minimizes the amount this will slow down your game. But like, if you make sure to have everything closed but your game, there isn't really a benefit to having more than 2 cores.
