“It’s like speed dial for computer memory”. Now I don’t think I’ll ever forget what cpu caches are.
Great explanation.

Excellent video. No verbal diarrhea. Earned a sub. I do have a question though...How important are any of the 3 cache levels for gaming? Is level 3 important for gaming? I just bought a PC and did a ton of research and I'm reading things like it can make a 10% + difference in FPS.

[MustafaKaradeniz-pxeq]

Oh God. thank you man finally i knew what is it

[dingdong.]

So, would you say that the lower amount of each level you have would result in lower game performance? I would imagine so, because the computer is not able to retrieve some commonly occurring files in a game. Good video!

[abdelbenz-llmy]

is the point of the cache to be small, or is it just a con of the cache

[mevlutcelik]

Hello. How much difference in video games would an 32 L3 Cache CPU do compare to an 16 L3 Cache CPU? (considering everything else is the same ofc).
Thank you!
