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.

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.
you are right. linus gets this stuff wrong quite frequently.
tobalnell1983 never noticed that :/. Than I probably have alot of information's that is not right...
Eric Slattery
Well, in fairness, the "big thing" about 64-bit processors is the addressing. But they only have 56 bits worth of addressing, and it still requires PAE, Yes, they do have a 64-bit data bus and 64-bit registers. But, even in "long mode," it requires a special prefix to access the registers as 64-bit. Data operations still default to 32-bit.
Eric Slattery
I don't think assembly language is that bad. It is, admittedly, tedious to do anything useful in it. (Disclaimer: In my early days, I did not actually have access to an assembler. I used a chart of opcodes.) Of course, I didn't have some lecturer teaching it to me. I learned it from books.
I'm not gonna read what you just wrote, because i actually have a life, and i don't have time for that, therefor i cannot say you are wrong, or correct you. I only read the first line where you say he's wrong. Once again, i didn't read yours, you might be right, Linus might be wrong, BUT. Linus does know what he's talking about, he wouldn't make a video about this if he didn't know. Not flaming, just saying, i haven't encountered a situation so far where he has said something wrong, and I've watched like 90% of his videos.
Man! This channel is very informative. Been watching more than 10 vidoes straight. Hope to watch more in the future!
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.

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.
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.
Thanks for the video. It's interesting, informative and funny. Well done, sir.
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.
surprised you were ignored am a fellow programmer well ex one but knew this all along coding for 32 bit is only redundancy while 64 bit is more free

a 32 bit computer can only handle information that can be represented by a combination of 32, 1s or 0s,. a 62 bit can handle info that would need more either 1s or 0s than 32. 64 in fact, so basically the higher the bit the more complex info that the computer can handle.
***** AHHHH thanks
+mauricious777 Actually 64bit Does have an advantage. 32bit clocks (which all run using some variation or knock off of Unix Time calculation) will reset sometime in the 2020s like the Y2K bug back in 2000 did for 16bit computers. 64 bit clocks will not reset for thousands of years.

We need a remake of this.
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.
Yes in a 100 years when phone applications finally require more than 1gig of ram well be ready.
***** www.phoronix.com/scan.php?page=article&item=ubuntu_1404_x64&num=1
According to this test (which was on a system with 4GB of RAM) 64-bit can increase speed quite a bit, but only in a couple things like openssl and disk transaction. Graphics were the same, CPU intensive stuff was generally faster on 64-bit with the notable exception of Apache. The reason is that x86_64 has twice as many general purpose registers and they're twice as large, so it can be significantly faster for some workloads. So there is some truth to 64-bit being faster, but until we get to 4GB I don't think it'll be too useful.
Alexander Pavel Essentially what I wrote just before you, though mine was more technical about it :)
***** Most software on Windows is still 32bit because Microsoft still support 32bit so the developers don't see the point improving things. It's just laziness more than anything. The simple fact a 32bit version of Windows is still being developed and released is baffling to me, they should have killed that shit years ago when Vista launched. It was the perfect opportunity to properly future proof the platform.
TalesOfWar maybe with windows 25
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?
The hype train over the number of bits was still in full force back then. But I think it also reduced the threat of emulators, but then again, the N64 and your typical PC (even back in the mid to late 90s) were still fundamentally different. Even the GameCube, Wii, PS3, and 360 were far closer to Macs (before the switch to Intel) because they were using IBM made PowerPC processors.
***** I think the 64-bit CPU could have been a legacy of the Silicon Graphics computers it was based on.

Probably because most developers are using 64-bit systems, now.
I think 32-bit is completely obsolete. My OS takes up about a gig just idling.
Most browsers take up about 300-700 megs, depending on varying factors.
A game takes up around 1.5gb. A modded game takes up to 3gb.
If I want to watch TH-cam vids on one monitor while playing modded Mount and Blade: Warband (with 64-bit .exe hotfix) on another--

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.
I'm very late but it can be fixed by just changing the Unix time counter to use 2 32bit counters instead of one
Great explanation. Thank you.
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.
LMAO "WHERES MY 128 BIT"
I LAUGHED SO HARD
16 bits. 8 bits. 4 bits. 2 bits! 1 bit! Half bit! Quarter bit! Ttthhhheeee wwwrrriiisssttt gggaaammmeee!!!!!!!!!!
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.
TH-cam 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.
It is not just about memory, it allows a CPU to deal with more bits of any given time, if you remember 8bit machines you needed quite a bit of instructions to deal with integers that needed to be more than 255 unsigned, when 16bits came along it let you do away with the amount of instructions needed and that meant clock cycles, also they were clocked higher so even more gain in performance, then 32bit came and things really moved on now 64bit gives us even more, face recognition and other stuf, multiple integer calculations in one instruction, it will be sometime before 128bit or 256bit is needed for the consumer market so they will remain as they are at the moment. Main reasons for 64bit is to process more bits at any given time just like always, and a CPU that is 64bit may not mean it's address bus is 64bit, just remember the 6502, the Z80 that was a 8bit cpu but its address bus was 16bit 64K max.
Yeah they tried to explain 64bit thing, but they didnt understand it very well

Very good! Easy explanation ;) Fun too.....Go Ahead
i love your taking style 😂
64 bits 32 bits 16 bits 8 bit 4 bit 2 bit 1 bit l bit aaaaa
16 billion GB RAM?!
*buys lots of RAM sticks*
Combine the sticks with chocolates in it will be delicious
Aldy P No please don't eat the ram
WARNING: EATING THE RAM WILL MAKE YOU GO BYE BYE
Thank you for these videos
Just got an ad staring linus on a video staring linus. The planets have aligned
POV: you trying to find new comment beacuse this channel got in your recommended and you enjoy it
Same
Good to know!
"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.

Ah yes, that was funny

Youre future, but I'm futurer

Me watchjng this video in november 2020 lol
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 ?
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.
64~bits 32~bits 16 bits 8Bits 4BITS 2BITS! 1BITCS!!! HALF!BITS! Q!U!A!T!E!R BITS
so how many bits is the wii u/ps4 linus ???????
PS4 is 64 bit because it has 8 gigs of RAM, Wii U, no idea.
32. they don't have enough ram to even use 64 bit. Especially the will u.
Francesco Fusco lol PS4 SATA 2- older than the wheel
LenChewbacca SATA II is totally fine. It's not bottlenecking anything. Not even bottlenecking an SSD because you wouldn't see transfer speeds going over SATA II specs when loading game files. And normal HDD just barely uses half of the available bandwidth of the SATA II interface.
***** It's x86-64. Like most Desktops and laptops.
Haven't been hearing about 32bits for years now
It's not (only) about the addressing. It's about the ALU and faster processing of larger values.
If it where only about addressing memory they could have just "add more bits" to the AGU. See for any easy the example the 6502 ;-)
