32-bit vs 64-bit Computers & Phones as Fast As Possible 

Linus: "but since the last fall's launch of the iPhone 5s" Me: "Wait, what?" * realizes this video was posted in 2014*

So you're telling me I CANT install my 32bit software twice to get 64bits???

2014: "Who knows we might need more than 4gb of ram in our phones" 2020: "yeeee maybe a 4² gb is enough "

Jesus.. I thought this was recent.. But 2014.. 😂 😂

I need 128 bit because only peasants use less than 16 billion gigabytes of RAM.

Hey! I see my video at 0:06 in the Google results!

"Who knows when our phones will need more than 4gb ram?" Yes.

And here we are now in 2019 complaining about phones with only 4 gb of ram 🤣

"briing on tha bits wheres my 128 bit" killed me

You're too fucking funny Linus, it's insane, you fucking crack me up everytime :D Love the show dude, been a watcher for years now.

1:32 "Hold on a second there, cool your rainbows my pony friend" - Linus, 2014

Basically 64-bit > 32-bit

"Bring on the 128 bit!" cracked me up faster than an iphone screen

1:20 That's what Linus' real voice when he runs out of helium.

This gets recommended to me as the 64 bit-32 bit-16 bit-8 bit-4 bit-2 bit-1 bit- 0.5 Bit meme is popular.

This video was uploaded 6 years ago RU-vid: we should recommend this in 2020

64bit system on iPhone still with 1gb of ram lmao

Fuck'n Linus, gotta love him!

Watching this in 2022 with a 12 gig ram phone and a 64 bit processor

Imagine someone from future sees this and laughing in 128bit

But... how can there be 16 billion GB of RAM when there are only 7 million GB of RAM on Earth? (I know, this comment is very, VERY original)

Pretty bullshit move by apple. stays at 1GB ram yet boasts about having 64bit...Thats like saying "HEY GUYS! I GOT A HUGE ASS SWIMMING POOL!, BUT I CAN ONLY AFFORD ONE LITRE OF WATER!!!!!"

32 or 64 bit is the size of the internal registers, which get processed at every instruction and not the size of the address bus nor the external data bus. 64 bit definitely offers more processing power, also depending on the instructions the processor offers, the kind of task and how the software is optimized for it.

And here we are in 2020 when even 16gb memory is a minimum recommendation

And now we're in 2016 with the OnePlus 3 and six gigabytes of ram...

16 BILLION GIGABYTES OF RAM! MWAHAHAHA I lol'd so hard.

2:49 Windows 11: "Are you challenging me?"

1:49 nice high pitched linus

I downloaded 16 Billion Gb of RAM, thank God I have a 64bit processor. Now my PC is gonna be super fast.

Sorry pal, but you misunderstand completely the concept of 32 bit or 64 bit for a microprocessor. When we talk about 32 bit x 64 bit we are talking about the size of the data bus not the size of the address bus. If we were talking about the size of the address bus your video would be correct because more bits in the address bus means more addressable memory. But when we talk about the size of the data bus we are really talking about the amount or the size of information which the microprocessor could work within a single unit of time. In theory more information being processed at the same time could mean more processing power but only if you take advantage of that extra processing power and only if you really need too. For example text information are stored usually using only 8 bits or 16 bits so a 64 bits processor wont offer much advantage over a 32 bits processor for text processing. For Audio processing, video processing and 3D Graphics were the processor must deal with big numbers at highest speed possible a 64 bits processor could offer a really big speed increase but only if the program is running 64 bit code and is optimized to work with 64 bits. If you have a 64 bits processor running a 32 bits video player for example probably you won´t get any increment in speed at all. In general it is a good idea to upgrade to 64 bits cellphone or computer because the microprocessor manufactures are reaching the maximum speed limit in terms of clock speed (specified in Giga Hertz GHz) so the only way to keep increasing processing speed is by growing the data bus size and the number of processors in the same chip. So eventually the software companies will follow the silicon chip manufactures and will create software optimized for 64 bits microprocessors but it only will happen if there is users with 64 bits gear to use that software.

Man! This channel is very informative. Been watching more than 10 vidoes straight. Hope to watch more in the future!

SIXTYfOur bits ... thirtyTWO bits ... SixTEen bits ... eiGht BIts ... four bits ... Two bits...

I wonder what Linus is like off camera... Completely off topic, but I wanna know.

This guy isn't boring at all.... Subbed

Now in the world of 2019 we have the Huawei P30 Pro with 8GB of RAM and Samsung Fold with 12GB of RAM "When we will have applications that use 4GB of RAM or more"

Thanks for recommending me 5 years later

I feel like each video I watch from these guys raises my iq a few points. Too bad feelings aren't reality.

"Briingg onn the bits ,wheres my 128 bit?!?" xD

I love your comments talk in technology to make things sound simple every one else complicates the subjects

u tell simple things in funny way. it makes ur video very interesting keep working good luck

i dont know why would anyone still use 32bit so old

16 BILION GIGS OF RAM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Awesome explanation, and as a software developer who has written a bit of prototype kernel code (assembly), I don't say that lightly. 😀 Kudos e.g. for mentioning PAE (Physical Address Extensions, introduced with the Pentium Pro, which allowed 32-bit processors to address up to 64GB RAM), and that most of the early performance gains were more from the increased number of general-purpose registers etc. than actual 64-bit computations. I have no corrections per se, but the 16 billion gigabytes figure at least does not apply to current desktop or server processors and may be slightly misleading. Current x86-64 (originally AMD64) processors - this hasn't changed since 2014 - only have 48 address lanes, and can therefore only address a "measly" 256 terabytes of RAM. The hard limit for future x86-64 processors - without introducing a new page table layout, that is - is 52 address lanes or 4 petabytes of RAM.

I was trying to determine whether I should start compiling my applications as x64! Cheers ma dude.

It's not only about more memory, the procesors in 64 bits can imput 1 more code line per command, and that's why programs are different in 32 and 64 bits.

16 BILLION GIGABYTES OF RAM HUAHAHAHAA xD Bring On The Bit !!

Very good! Easy explanation ;) Fun too.....Go Ahead

LOL nice expression at 1:18

I thought this was going to be some fancy behind the scenes magic that you don't see, because that's what it sounded like in the WAN show, not just "more RAM".

*Makes a phone with a 64-bit so it can handle 16,000,000,000GB* *Keeps with 1GB for two more years* -Apple.

Even as a tech person, this 64 vs 32 has been bothering me for a while. Thanks for breaking it down!!

Thanks for the video. It's interesting, informative and funny. Well done, sir.

Informative video. I know it's hard to compare speeds of various tasks between the two, but a couple of examples would have been instructive. I do have one example, though, that I found out by doing a comparison on my computer (a recent Alienware model) Adobe Premiere Elements 9 32-bit vs. Premiere 15 64-bit to produce a half-hour AVCHD file. Same hardware, same movie, but the former took around four hours to encode and the latter almost exactly ten minutes. The difference is so stark for this particular application that I'm still slightly stunned. There is the possibility that I'm under an illusion that I'm comparing apples to apples, so I welcome others' thoughts.

Someone please make 1:28 - 1:30 A MEME

Just got an ad staring linus on a video staring linus. The planets have aligned

It is not only a matter of size of RAM you can access but also of speed of floating point operation. I have seen factor 100 improvement between 32 and 64 bit application for matrix inversion operations.

Talking as a programmer, there is a benefit which I'm surprised you didn't mention. 64-bit processors can read 8 bytes each instruction and 32-bit only 4, which is hugely beneficial for 64-bit data types used in data processing of huge numbers or high resolution decimals.

Why do they upload this video in 4k? Who watches that? Seriously?

Aside from the accuracy and general quality of the video (which were excellent as usual), you even got a good laugh out of me at that "16 billions GBs of RAM". Thanks :D

We need a remake of this.

i stil dont understand lmao

I was watching 64bit 32bit 16bit 8bit 4bit 2bit 1bit meme and i got this recommendation

Amazing guy, extraordinary explanation! 😁 +1 subscriber.

Great explanation. Thank you.

64~bits 32~bits 16 bits 8Bits 4BITS 2BITS! 1BITCS!!! HALF!BITS! Q!U!A!T!E!R BITS

literally all flagships are 64 bit and supported here in 2018

About to skip the ad until I noticed linus was in there

This pop up on my recommendations because of the new 64, 32, 16 etc bit meme

16 bits. 8 bits. 4 bits. 2 bits! 1 bit! Half bit! Quarter bit! Ttthhhheeee wwwrrriiisssttt gggaaammmeee!!!!!!!!!!

Back when Linus' 4 minute videos had an almost 1 minute Sponsor segue

i love your taking style 😂

After 4 years......WE REALLY NEEDED IT......

Good to know!

Sure for now saying that a phone has a 64-bit processor is just a selling point, but it makes for a more seamless transition in the future. In Apple's case, once mobile application require 4+ GB of RAM, they're already going to be a few generations in and app developers will already have compatible apps. Pretty forward thinking if you ask me.

The bit width of a processor is not only (usually) translated to the address bus, it's also the width of internal CPU registers and, together with it, the operations on the registers. As a simple example, in C/C++ the "long long int" type (I know, it sounds more like the beginning of a fairy tale) is 64 bits, no matter what target platform you compile the code to. If the target is 32 bits, an operation over the variable has to be done in parts in machine code, while in 64 bits it can be done with a single operation.

your vocals are good in this vid than other vids ; )

I always learn something from these videos, outstanding as always Linus!

'16 BEILLION GEIGERBAITES OF RAM MUHAHAHAHA' linus 2015

Well, it does have one other performance increasing part, using longs as their native if you work with big numbers. And also, you get int128_t using the same trick as longs in 32bit does (and fancy 256bit stuff using AVX). Allowing you to work with even bigger numberes without the need to use any fancy big number libraries. A major drawback, 64bit pointers take up twice the amount of ram. Which is why many applications that is pointer heavy tend to increase their memory usage by 50-80%. Hench why we are stuck with many low memory usings applications still being complied in 32bit mode.

"Bring on the bits!!! Where's my 128-bit??" I laughed hard with this XD

"Maybe we will need more than 4gb eventually" Anything in 2022: you need a minimum of 16gb

64 bits 32 bits 16 bits 8 bit 4 bit 2 bit 1 bit l bit aaaaa

Your channel is awesome.

For me the video started with a Linus ad. It was funny

I'm surprised you did not mention the Y2038 problem Linus. Yes I know it's still a long way to go, but it is a very valid reason to migrate to 64 bit architecture.

LMAO "WHERES MY 128 BIT" I LAUGHED SO HARD

Once I selected this video, I just saw a Linus ad. A Linus ad on a Linus video.

Tech has really moved on so much from where it was in 2014. Surprisingly, the industry did work together pretty well to quickly transition away from 32 bit processors between 2014-2017. Only the very low end of devices are still using 32bit archectures these days.

"Up to 16 billion gigabytes of RAM. wahaahah!" Yep, we need about that to run our favourite Java programs.

64 bits, 32 bits, 16 BITS, 8 BITS, 4 BITS, 2 BITS, 1 BIT

"Cool your rainbows my pony friend" I died XD

Please differentiate between address bus width and data bus width they may on magnitude be the same. The original 8 bit CPUs had 8 bit data buses but 16 bit address buses, so the width of the data bus did not define the memory range that could be addressed.

POV: you trying to find new comment beacuse this channel got in your recommended and you enjoy it

Watching in 2019 and still very useful

could you please suggest me a good laptop to use photoshop for a professional use?

Is there more to it than that? Why did Nintendo go with a 64-bit CPU if it went nowhere near that amount of RAM?

But damn apple does the right thing slowly moving over to 64-bit. its gonna be a perfectly smooth transition for iOS users. When i get my first 64bit android phone there'll probably be no support for 64bit apps.

RU-vid has recommended me again this video. Well, I've learned some computer engineering, and I was studying the Intel manual of Intel Architectures of 32 and 64 bits... And believe me. It's HELL. It's just not that simple. The implementation at scary low levels is very complex. Though I'm beginning to understand it better.

My smartphone have a Snapdragon 625 processor which according to Qualcomm is 64 bit, but AnTuTu benchmark shows that my device although being ARM v8A, it's having the Instruction Set at 32-Bit Mode(Arm V7l). I don't get it, what does this mean. Is my processor 64bit or 32bit. Is it possible to upgrade the instruction set from 32 bit to 64 bit ?
