How Do CPUs Use Multiple Cores?

A common piece of advice for PC gamers is that you don't need tons of cores - but why are games often unable to take advantage of CPUs with many cores in the first place?

    So. Some games and workloads are cpu heavier while others are gpu heavier?

    When buying a cpu u want a balanced breakfast of l cash cores and and ghz

    1:42 So, both CPUs will have to execute three operations according to the sketch. Why are we supposed to gain speed then?

  • August Batch2015

    Is that even explanation , the rhythm of speech is like a robot

    But Linus, what if I want to play games. Record, stream and watch techquickie video all at the same time?Wouldn't more cores help with multitasking?

  • terry waller

    You have to be careful, some software such as Oracle are licensed per processor. They count 2 cores as one processor.So if your paying $20,000 for one processor you get charged $40,000 for a two processor or 4 core system.

    You sound like Todd Howard lol.

  • hdjksa52

    Hmmmmm I remember when we used to just look at the processor speed.

    40 cores will be reality thanks to amd #threadripper

  • Grantham

    Correction: AI runs better on GPUs. Operations are easily reduced to matrix dot products. If whatever you are referring to works better on a CPU, I’ll bet $$$ that it sure isn’t actual AI.

  • Haris

    40 cores is sorta like a possibilty now looking at the threadripper 32 core :o xD

    Hi im saving up for gaming on a PC and I have absolutely no idea on how to build one I was just wondering, is it real overwhelming to have 6 cores with a GTX 1080 TI Graphic's in your pc ?

  • Kuro Murasaki

    Would like to see this revisited as it appears from hwinfo64 that most games are using 8 threads pretty evenly these days; even something like WoW that was notorious for using 1.5 threads/cores; ask Luke ;)

    1 main earth core - 2 cores go's as soccer one side net | in middle score gole | < net . Other two cores to other net keepers. 11~11. = Apple is one tree but one Apple tree needs other Apple tree to reproduce oxygen. Logically grows other two Apple tree's to bring piece - clearer oxygen with peace ( faster movement or lighter earth ). So apple it self from one point go's 4 threats. Like in nature free will of fly, like jump in air and feel free will oxygen - it pushes that one Apple have 4 threats naturlly , Pure oxygen - piece brings cleaner oxygen. Procesor it self two tree's and fan two tree's :-)

    2018- You can get a six core for gaming. 2019- You (probably) can get an eight core for gaming.

  • Not Your Everyday Timelord

    I went for a core i3 @ 4.2 (OC'd to 4.9) over an i5 or i7 at lower clock because I don't own any games that run on more than 2 cores anyway.

  • Blink

    Should I use sync all cores or per corePls help what gives better performance?

  • Morgan Hall

    Guys, this is all really good advice, but bonus tip: if you plan on doing anything like video editing and the like, you really should have a 6+ core count.

  • imad maftouhi

    Hey Guys, I come up today to you because I have a problem that is bothering me a lot !So the problems is I have an Intel Core i5-4310M CPU @ 2.70 GHz that is supposed to run with 2 cores. But when I open the task manager it only shows me 1 cores and 2 logical processors with the virtualization enabled. Pls help me with this cauz it really limit my gaming experience

    Crazy Youtube...Youtube showed me this video in 144p (before I manually switched to 720p). Looked like a 1998-version of Youtube.

  • Fistagon777

    64 cores baby, amd epyc proccessors baebaeeee

  • Alina Hänel


  • RocketLR

    Why didnt you explain Logical cores?! >.<


    I got an i7 because in csgo it gives me 400/500 fps more, because is a CPU bound game.

  • alvin jb

    can you make a video about blockchain??

  • Mukesh Singh

    its 2018 and is the 'above 4 core is an overkill' and waste of resources still true or should we go a bit higher?

  • Matt

    0:14 phones looked like that 2 years ago... wait they actually did

  • David Dil

    I need as many core as my wallet can hold. Xeon 12 core. Got to love VM

  • WestHills Games

    When will we get 200 cores in our phones

  • HighScore

    HAHAHAHAHA 8 coresBoo! You suck!
