coulter914 So Linus. LINUS IS LIFE.
Hi_Im_Lee I'll start the story. you add on: *I was only 9 years old* discuss
My laptop fan goes into TURBOBOOST when I open google chrome.
+Nano Boyut CHromium is EXACTLY same thing as Google Chrome, Chromium uses google chrome´s core made by google.
+Aleš Nezbeda (SlouchyButton) Opposite, Chromium is Google's open source WebKit (now forked to be Blink) browser engine which Chrome is based upon. I would however expect their CPU and Memory efficiency to be fairly equal though.
+CreeperCraft137 pretty much all devices do that.
they always say "more performance when you need it" but it's really "more performance whenever possible" and that can really fuck with your battery life/heat especially since you can turbo boost on all cores at the same time (which really kills battery life)
thats why for times when im going to constantly have a load on my laptop (say watching a video in a web browser) I turn turbo boost off
+Aleš Nezbeda (SlouchyButton) only difference is it's open source, has less compatibility with formats and doesn't have a flash player. You should install it yourself. I don't think there is much difference between them unless you hate properiotary software and love google chrome apps and extesions.
+SecretPotatoChip I use Google Ultron.
Fun fact: the first so-called "turbo" CPUs were introduced around 1987, and they ran at a whopping 8 MHz, instead of the normal 4.77 MHz. And if you wanted to play games, you had to turn off turbo mode, otherwise they would run too fast! (Because most people didn't have the foresight that faster CPUs would be developed, so they programmed the game's timing to be based on the CPU's clock speed.)
***** Asians play it at 120fps. Yea it sucks.
same thing on emulator.
interesting...
I remeber having to press the Turbo Button, in order to play somehting.
Funnily enough, things like that still happen today. Some games change when played at a higher framerate. Most recent case would be Titanfall in which a lot of actions in-game happen faster if you're playing at 120hz vs 60hz. Your weapons will shoot with a slightly higher RoF which is quite nice if you have a 120hz monitor.
Were is my end video AD Linus!!??? RIOTT!!!
Mitchel Paulin hehe

At that point the real content of the video is over so you can stop watching it at that point.
dollar shave club is awesome
Mitchel Paulin It's not really a third of the video if it happens after the main part is done. I like these in-video ads, because they're (semi) relevant, non-annoying, and 100% goes to Linus Media Group instead of Google and whatever ad agency made it.
Mitchel Paulin you are free to stop watching.People are so sensible nowdays. facepalm
Was a lot more in detail than I expected. Good job, Linus!

This is one of the best videos you have made, as it went through the timeline of changes in the CPU's.
Could you make more Timeline videos, to see all the different components, where they started from to where we are now?
You know what else is cool? Linus
Thank you!!
I just got back into PC, upgrading from a Phenom II X4 965 to a Ryzen 5800x and I was a little confused on how Turbo Boost worked.
Fun fact: This is a rare sample of a Techquickie video without a sponsor that was created after Linus Media Group was made (actually it might be the only one)
Yeesss! A video without integrated ads! Like in the good old days. Keep it real like that!
Love the videos linus. Im educating myself so that i can builad a custom pc for recording music. I have a basic knowledge, but your really helping me distinguish my actual needs vs unnecessary hype. THANK YOU for making these videos.
I'm going to like EVERY next video that's without any ads.
Too bad I can't feed "likes" to my wife and son :p
But seriously without additional advertisers, a show like Tech Quickie would be losing me hundreds of dollars PER EPISODE and I wouldn't be able to keep it going.
Hopefully you understand.
LinusTechTips
Sure, I get it :)
If only youtube was placing its ads at the end of the video...
Please continue keeping them at the end of your next episodes. That's the most neutral advertising which I respect
Making people watch 15 seconds of BS against their will as youtube does isn't right...
Good show by the way. Keep going.
RCTPAVUK if TH-cam put the ads at the end people would watch the video, then the as would come on, then they would quickly leave and go watch other videos(maybe porn)
underpantcockroach
That's exactly the point. NOBODY has ever had a thought "ah, let me follow this advice" during watching these ads. On the other hand, EVERYONE is annoyed (and it's an understatement) by the ads.
If people are passive about it, somebody (veryverybadword marketers) may one day decide that a mandatory 60 seconds of advertisement is ok...
Well, anyways it's not the place to debate about ads :)
I absolutely loath ads. I block them regardless, but can understand and tolerate the shameless plugs... but man, That was hilarious! xD
I like the view because your didn't sell me anything (ad) and didn't say a stupid intro... Direct to the point... Thanks
Achievement :saw a techquickie video ending with no ads !
you explained this like an absolute legend. thanks, man!!!
One of my favorite tech quickies .. Didn't know to much about processor history
Some of the best video/audio quality on youtube. GG
Damn Linus did you really have to fuel fanboys by only talking about Intel/Nvidea? AMD cpus have a turbo clock and AMD Powertune (might have that name wrong) adjusts graphics card clocks. As well as I, for one, do not know exactly how AMDs solution for CPU turbo works. It would have been nice if it were in the video.
It works basically the same way.
Techquickie Oh well okay then haha, thanks. I figured there would be some kind of difference.
He also forgot to say that the first multi core CPu was from AMD...
andybruintje
hes paid by Intel, so he can't reveal that information XD
andybruintje Considering the video was not on multicore cpus, thats not a big deal. When the video is on turbo frequencies however, he should have mentioned AMD does it as well as Intel/Nvidea.
AMD: Higher Base clock
Intel on steroids (high performance on): Oh hi fck ur electric bill
3:44 This bit got me to like the video
I love this ''as Fast As Possible'' series so much if you do a build guide i dont understand some things cuz. (my language because you explain things differently in more american english).
but this makes it so easy coincidentally. I already knew what was turbo booster! Thanks very hard for these videos Linus ill be happy if you make more!!!!! (this text is transelated)
AMD Turbo Core boost all cores or what? You didn't cover that.
AMD, is that a brand?
RemX405 um...yes...it was in the video...
AMD does 4 cores boost slightly, 2 cores boosted more than 4 and 1 boosted more than 2 - only one can be active at any given time and it'll automatically pick based on the workload
RemX405 Ignorance is great to have, huh?
RemX405 fanboy
Super good! Everyone into tech should watch these to learn. Explained perfectly!
at 3:08, shouldn't it be Core 0, Core 1, Core 2, and Core 3?
I'm just being picky since Linus usually likes making his video really accurate. I'm just suggesting improvement, so don't kill me XD
yes
you disliked the video? Even me! ""
first time watching ur videos and they r awesome dude😀
ikr
Really informative video, I thought I knew how boost clock worked - I was wrong, nice with that history lesson as well, overall great video, and... I gotta love the 'Speaking of pretty cool - my CPU in idle' made my day ;)
I just discovered by experience that if you produce music, you should deactivate intel speedstep because it causes cracks in the sound when it changes frequencies and the sequencer becomes instable. I didn't find any post in forums talking about it but when I deactivated mine (i6700) my workstation stoped the cracks and bugs and I got a lot of headroom to ad virtually as many plugins as I wanted :)
Thanks Linus, I did not understand what Turbo Boost & Processor Efficency means! Thanks & keep it up sir!
niCe, lots of useful information presented in a way i can understand it, quite refreshing. after watching just a few videos i'm gonna have to give this guy thumbs up and 4 and 3/4 stars.
Great video, Linus! I like the look into history.
thanks mate, im learning all this stuff to see what i need in my own desktop. your videos are really helping
finally a video with no spam
i am impressed this was even uploaded
Best non-ad ending ever. Love you :D
after seeing this, even my gramma could understand dynamic clocks, great job
Haha not me lol
I enjoyed the background on the industry that led up to the point of the video. I'd like to see some more of it. It might work well as another show on the channel. :)
Great Job, the best PC Hardware youtube ever
Fantastic videos. You are very well spoken and communicate things very clearly in an easy to understand way. I will be using your channel to learn and better understand computing from a laymen's perspective and to help me purchase my next pc.
Linus you have made a mistake at 1:30 you need to inverse them LOl
For some reason , i thought turbo meant that all cores go to that number . Good thing with Linus ! (keep rocking bro)
no add was actually very refreshing. i think i will like this video :)
I know that this video was made almost 5 years ago but thank you!
You're a king, dude. Awesome videos.
Awesome, No Ad!!!!!! Great video.
the whole video is an ad....
Well explained.
I am now tempted to enable my turbo boost and give it a try.
Super cool videos TechQuickie! great TH-cam channel
1:06 Well, guess what, now we're back to the good old days
That outro was very nice and much better than the usual ads. I don't mind them but it's nice having a break from seeing u be some companies b**** and see u beg us to buy their products. I already buy cooler master products if that helps to decrease the ads overall lol.
Best computer channel ever thank you.

Nice presentation broo🔥
even 8 year later.... linus teaches me things
I went form a hot running AMD quad core running at 3.2GHz max (AMD Phenom II X4 955). It seemed to turn off cores it wasnt using either, while during idle. However, ive never seen it throttle its speed during idle.
Now i got a i7 4770K and its a world of difference... i should mention i also have a Asus Z87-Pro motherboard, that comes with auto-overclocking features.
single and dual core run at 4.3GHz and triple and quad at 4.2GHz. However, getting it so far to go all the way up, ive only ever seen it use 4.2GHz.
During idle that thing will drop down to 800MHz and use 0.1V or less across the cores.
Its so good i sometimes miss my AMD heater lol.
... AMD, heater? you have no idea what you're talking about, the old Phenom 2 X4 955 had a heat cap of 62c, I had mine OCed to 3.9ghz with FSB 182mhz or 282mhz (cant remember) running at 56c max load.
Heaters? you must be talking about Intel
my i5 3570k oced to 4.7ghz runs 85c-90c
why lie?
you may look at the raw numbers and think its the opposite, but im talking from experience. Perhaps you were thinking of full load situations, in which case you may be right. But im talking regular use across the day: internet, gaming, word, movies, music, etc.
At least in my personal experience and situation - and ofc, yours may be different - my tiny game room was constantly hot with the AMD core + a GTS 250. Now with the i7 and a GTX 780Ti; both supposedly running hotter than the previous pc, my room just doesnt get that hot anymore.
During winter i didnt need a heater, literally no need, when my old pc was on. The current one doesnt heat up the room as much at all.
The reason behind it, i think, is due to the decreased power consumption during low load tasks - where AMD would be revving up the CPU to get the job done asap and only slow the CPU while idle.
*****
thank fuck I have 3rd gen xD
***** woot, dodged that one. I7-4770K doesnt have Intel V-Pro on it.
i do take away from it that we should look deeper into the 'special features' of the hardware we buy.
Weird. Im using an AMD CPU and it throttles my frequency down to 1.7 GHZ when im not using it and has a non OC-d max at round 3.9 GHz ish.
"Remind you to subscribe if you haven't already" is so much better than "and as always don't forget to subscribe". "As always" implies linus is addressing viewers who's been here before, who probably already subscribed. To new viewers as always doesn't make any sense since they are new. Either way wouldn't work. So glad Linus finally changed it up so it's not conflicting.
no need to beg Linus, I _always_ like your videos before I even start watching them! I just know it's gonna be good even if I already know about the subject!! :-P :-D
Thanks as always Linus great vid.
I noticed, Linus, that you are the only youtuber who gives us an option to dislike your videos, which makes you come across as more focused on delivering better content and that you want honest feedback rather than the most likes. This makes me more inclined to up vote your videos, even though I usually never rate videos (and these are well deserved up votes).
Yeah I was about to cancel my order of a Dell Inspiron 15 5000, 2019 Flagship, because the stats said 1.6GHz processing speed "up to 3.9GHz". I've always been used to just one speed so thought this would be slower than my current 2.3GHz processor. I thought I'd have to buy new hardware to get up to this 3.9GHz or whatever speed I wanted higher than the 1.6GHz. After doing some research online I found what you say is the case now. You can control your processor max output now and the computer will use the speed that's needed. Crazy. Glad I canceled the cancel LOL.. cuz it's a nice computer with 12GB RAM and 1TB hard drive. It also has a number keypad which I've been missing in all but my 1st laptop. That'll be great because sometimes I have to take tests and will also use the computer for some work functions. Thanks for your info here just proving more how things work now. This one has an i5 Intel processor.
I didn't no that turbo boost was for 1 core only. I thought it was for the whole CPU. A little more power when you need it.
That's why Intel's CPU's are much better for gaming :D
Aren't all the consumer grade processors "Symmetric Multi-Core Processor" designs?
Which means that the oscillator, and a few other expensive parts (float point arithmetic unit, encryption acceleration etc.), are shared between all the cores. This finally boils down to all of the cores running at the exact same speed at all times. This is done to prevent one core from accessing the cache/ram at a frequency which is different from the other cores. Basically prevents the processor from tripping and falling on itself.
There is this other thing called "Asymmetric Multi-Processing" which is usually found in the more expensive server counter parts. These processors have cores which are all separate processors in themselves and can run at different clocks independent of their sibling cores. ARM recently announced that they will be designing the next gen mobile processors on this design but we'll probably see those coming in quiet a few years down the road.
Now coming to the turbo boost, keeping the marketing gibberish aside, what it really does is prevents the computer from chocking when given a very heavy load ;-) . It's very similar to how youtube pushes the start of a video at a very fast speed then slows it down as the video progresses, all this while figuring out the optimal rate at which they should push the video to you and somewhere through the middle it transfers exactly at the rate that's required to stream the video smoothly on your computer+internet. The processor power management is very similar to this. The video is the program you are running, the speed is the thermal limit. The processor boosts the clock speeds in the start of a a series of heavy instructions so that it can slow down later while it calculates how to manage the next bunch of instructions in the most efficient way possible.
GPUs on the other hand work exactly how Linus explains. They boost up if they are running cool and clock down if they are heating up. That's why it's recommended to run high end GPUs in a well ventilated chassis.
AMD and Intel in a tank? more like, Intel in a tank and AMD in a rusty bathtub with wheels holding a shotgun.
Fanboys suck, stop being a fanboy (If you continue, then you're such a waste of flesh). Fuck fanboys and fuck brands.
Xavier Lim I ain't a fanboy I'm stating it how it is. But, AMD GPU's, now that would be a tank.
+Chubby Kid Nvidia or AMD for your preferred GPU?
DularaW AMD. Unless it's something like a 750 TI, 760, 950 or a Titan.
ok I don't care who is better this comment is hilarious
way to go to ignore AMD while AMD has a similar technology..not forgetting that AMD made the first multi CPU.
Google "IBM Power4".
Noh, steeve jubs did, duh...
AMD Cool and Quiet was introduced 3 years before Intel Speed Step. Linus being a shill as usual.
@@goku445 Did you mean Linus?
@@electronichaircut8801 yea
Sooo, Linus said that one core gets boosted during Turbo Boost. I just checked the Intel website and it said that (at least the turbo boost 2.0 technology) can boost ALL cores dynamically. Soooooo...uhh...yeah?
Didn't say that only one gets boosted. It's an example of how it works. Sometimes all cores will get boosted, sometimes a couple get boosted, but to reach the maximum turbo frequency only one core gets boosted.
I'm glad you asked this Question man. TechQuickie's response just made it ALL clear for me. Thanks Techquickie, you guys rock.
this was the most succint and complete explanation I've heard. thank you

Didn't know Linus Torvalds did videos. I must have been living in a rock. :(
Linus, how about doing a tech quickie on how turbo boost and power saving should be while overclocking.
Trying to buy a new laptop. I knew I could depend on you to make it make sense.
Watching this after 9 years🗿

God I must say LTT (LGM now) is in my opinion the definitive ideal in news broadcasting, keep up the good work & diverse content 💓👌🙌
@techquickie - I think that you got your pictures inverted at 1:32!
Yeah!
linus you've done videos about wireless routers, but never about wireless usb ADAPTERS.
I have used many of them and seen crazy stuff.So if you do make a video definitely include ALFA adapters(hackers delight + AMAZING reception).
HI!
Just a comment. It's not like a single core will get the boost that "turbo boost" says.
Setting an example, when I got the i7-4770K, the CPU0 got a 39 multiplier under full load, but the second (CPU1) got 37. CPU2 and 3 got 35 as a maximum. Temperatures were high accordingly to the multiplier.
I dunno about the rest of the models, but I can assure you 4770k works this way. At least on stock. OC I got more and even frequencies among cores.
Anyway, good vids!
L8er!
your videos are awesome!
Linus you are amazing!
I think I accidentally walked into my history class...
Edit: I think I accidentally answered my history call
Nice video, like always
you sir are a bit of a guru :) thank you for all your information
I like how Linus does "but" in a different shot.
I'm jealous of your on-camera talent. LoL!
Quick quick question guys, if the temps allow it, call multiple cores (maybe even all of them) reach the boost clock?
Yes, at least on my 3770k you can select if you want a single core to increase or keep them all at the same clock speed and boost all together (but heat builds up really quick...) 95C on stock cooler at 4.3ghz (normal turbo is 3.9 on a single core)
Tomás Jarsun that's called overclocking. completely irrelevant.
Unfortunately I believe the answer is NO.
There is a set limit for each core during a certain usage case. For instance when only one core is used you can get the full boost clock (like 3.9ghz in this video) on that one core, there is then a speed (something like 3.7ghz for the processor in this video but I don't know the exact number off the top of my head) for 2 core use while the other 2 cores sleep. If you are using all the cores then the "normal" frequency (3.5ghz in this case) is all you get.
However as bogellenong has pointed out, if you have a intel K series processor (or most AMD ones) and your temperatures are fine, you can increase the clock speeds manually via the bios to "overclock" the processor to higher speeds. there is a lot of information available on this topic but if you accept that you many need to increase the voltage and you keep max voltage and temperatures within safe limits then you can effectively achieve the exact same result as having all the cores "boosted" by the cpu.
With a good cooler most (not all, see silicon lottery) i7 4770k chips will reach at least 4.2ghz stable, a full 300mhz faster than the one core boost speed. Some chips even get 4.5 or even as high as 4.8 on custom loop water cooling systems. However bear in mind it can take a lot of time and mucking round to get there, its not a case of change 3 settings to the same levels as everybody else and you done.
Thanx for the info guys, I already know how to overclock but until I saw this video, I thought the boost clock was able to boost all cores at the same time as long as the temps were good. What can I say, learn something new everyday.
if you have your cool and quiet (or whatever it's called with intel) enabled, the cpu will only be as powerfull, as it needs to be. so if you overclock, you kind of set a turbo for all cores, cause it only will be at that speed, if it needs to be.
Remarkably helpful. Thanks!
Commenting because I love Linus.
Thank you for your fast & direct information so I do not have to read the manual and fall a sleep.
Then what does overclocking do? Does it just change the maximum speed for one core able to reach or a clock all cores can reach at the same time?
You are changing the normal running speed of the CPU, not the turbo boost speed. Some mobos have the ability to change the turbo multiplier but most people turn off turbo boost to prevent instability during overclocking and normal use ( the normal clock speed will be higher than turbo speed after overclocking anyway)
patx35 OH, thanks! That clears up a lot of my assumptions!
It all depands really on how you did your overclock and if you turned off the Turbo Boost. I run an FX-8320 at a fair stable everyday OC of 4.4 GHz. I use no Turbo Boost, No Cool N' Quiet, No C6, No modifier to any of the CPU stuff so mine ALWAYS runs at 4.4 which means that unless I turn the machine off I have more power consumption overall.
i want to oc single thread performance, could i just have as in the video the 3.4ghz on all 4 cores and oc the boost to 4.6ghz
Plusthinking Iq I don't think so unless you can OC the turbo boost
Thank you Sales Team™ for not selling the ad integration. Was kind of a shocker.
