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?

    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 ;)

  • Timur Bani

    Rewathing this vid realising we went from dual and quad to 32 core cpu's

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

    Your ads are too long. Video ad(s, depending on video length) + video banner + in-video ad not enough?

    Advice to settle for ~4 cores is more of a reflection of the gouging prices than anything else...

  • Blink

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

    I have a dual core. I was wondering why it is, when i click on multiple programs that i need to have open all together, the computer only opens one at a time. It seems after the first program opens i wait as long as usual for the next one to open, as if i had just waited and clicked after the first opened. Shouldn't one core open one program while the other core can open another?

    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?

    I love you and your information

    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.

    i think this is a problem for microsoft to solve the os witch the game engines run on should be able to force the engine to use more cores or emulate a one core cpu that spans all the cores but appears as one core to the game engine. then older and current games would bee blazing fast on a high end cpu

  • GAMER KORAY

    i3 6100, acts as 4 cores but has 2, because of the 4 threads

  • David Dil

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

  • Trooper_Z

    Do "Techquickie as fast as possible"

  • Taris Iskandar

    We almost reach 40 core today....

  • Jason U

    came here to say .... 68 cores now

  • John Bracciano

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

  • jerrylee22

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

  • Fusk

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

  • Clark Kent

    40 cores XD id buy that

  • Kentium4

    Welcome to 2018, 2016 Linus where 40 cores is possible (32 right now for consumer)

  • Patrick Enger

    You sound like Todd Howard lol.

  • NA

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

  • Matt

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

  • Bashar Adama

    Thank you, my company YouTube will give you money for views about every videos. you made it. please, don't you forget your money.

  • 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.
