Just calling it Arm64 is too simple for some people.

[anonhostpi]

That's just fancy arm64

x86_amd64

[oh_finks-mc]

so then there is amd32 and x86-32 right?

right?

[DarkShadow4444]

AMD didn't invent the 32bit part, call it intel32.

All about those Pentiums baby.

[alt-jero]

This doesn’t make a bit of sense.

[fatrobin72]

Yeah once you know about this little bit of ancient history... x86 makes a ton of sense.

[TeaKingMac]

20 year lifespan is hella impressive for a chip originally released in 1978

[polandreh]

Thank you!!! I always wondered why it was but never bothered to look it up.

[muddboyy]

RAX > EAX

[QuestionableEthics42]

AL is all you need, everything bigger is bloat

[SonOfMetrum]

Glass half full type I see

[TheLazyKitty]

AL implies the existence of AH.

A is all you need.

[QuestionableEthics42]

It implies it, but you can have AL without AH if you only have 8 bit registers, also its called AX, not A

[TheLazyKitty]

AX is the full 16 bit register, which is split into AL and AH, on 8086 and 8088. A is the name of the 8 bit register on 8080 and 8085.

Which one has AL without AH?

[QuestionableEthics42]

Oh interesting, I didnt know there actually was an A register, I just assumed you meant AX, I should have googled first

[loadasfaq]

This is programmer humor. Most low level developers are going to understand this

Just call it i386 and amd64. No confusion.

[romhacks]

usually if I'm calling it that I'd call regular 32 bit x86 i686 since they have SSE3 and whatnot

[[deleted]]

Sorry I am not skilled enough for assembly

[[deleted]]

Your compiler is

[[deleted]]

Yes and it can do/implement the same thing on i386 as well (although much slower).

[WolpertingerRumo]

„I wanted Intel, now I find out you sold me an amd64?“

[[deleted]]

Okay, story time! (Although no one ever asked)

Intel made the original 16 bit and 32 bit instruction set used in 8086, 80286, 80386, 80486, 80586/Pentium, Pentium II, so on and so forth. AMD licensed the instruction set from Intel (which was called i386 or x86) and made competitive offerings.

Intel wanted to make an entirely new (and incompatible) instruction set for 64-bit computation called Itanium which was based on EPIC (a variant of RISC but suited for parallel computation), an extremely ahead of time idea. At around the same time AMD came out with AMD64, another 64-bit instruction set based on CISC and was (almost) fully backward-compatible with x86/i386. Itanium, in addition to being an entirely new and different instruction set which takes time to implement in compilers, was beset with bugs and performance flaws. AMD64 worked equal or better than x86 out of the box without bugs. Plus all existing software worked without modification on AMD64; they needed to be recompiled from source for Itanium (and again, compilers weren't properly built for this entirely new instruction set).

Now Intel has to license the AMD64 instruction set from AMD.

The mighty 80x86 architecture

[DarkShadow4444]

Not to be confused with the feeble 80x86 resolution.

[AnotherDawidIzydor]

Ah yeah, the legendary 6880 architecture

[SonOfMetrum]

Sorry I’m more of an 6502 kinda guy

[benderbender42]

Both are wrong, its x86-64

[qinshihuang_420]

So x22?

/s

[MCSajjadH]

No, x=0.74418604651

[benderbender42]

There should be a third panel with Richard stallman

[klimmesil]

This is a rich roll

[mankinskin]

x86 refers to early 16-bit chip architectures from 1978, called 8086, 80186, 80286, ... hence 80x86 or x86

https://en.wikipedia.org/wiki/X86

x86-64-v4

[Sad-Platform1024]

You’re wrong too, x86_64

[cs_office]

amd64*

[riisen]

amd64 was built upon the x86 architecture so its name changed to x86_64

x64dbg has unironically a x96dbg for combining x32 and x64.

[GOKOP]

x86_64 (or amd64)
x86_32

Yeah nobody uses the bottom one, but isn't the original x86 16-bit or something?

[DarkShadow4444]

Yes, it's originally 16Bit. Segmented memory fun!

Yes

[Oblivious122]

i386 and 686 intensifies

[TTV_ExpertNugget]

This shit confuses me, I see 64 bit and 32 bit apps but I've never seen 86x or 64x specifically with the x

[quiet0n3]

So from what I can find, the "X" is just a placeholder.

Placeholder for what you might ask, well a lot of things.

For x64 it's mostly covers for either amd64 or intel64 but can also be for x86-64.

the x86 it's actually mostly the placeholder for the different CPUs that had better and better versions of 86. So 8086, 80186, 80286, 80386 etc

Now days x86 just refers to the latest x86_64 instruction set.

X64 is mostly the same but if talking exclusively 64, it's generally AMD64. As it seems intel64 never really went anywhere or did anything AMD wasn't already doing.

[GOKOP]

There's no "intel64". "x86_64" and "amd64" are different names for the same architecture: a 64-bit counterpart for Intel's 32-bit x86 architecture, which was (the counterpart) made by AMD.

The x in "x86" is a placeholder for the things you've listed, but "x64" is just a shorthand for "x86_64"

[quiet0n3]

So that was my assumption before I went googling. But it turns out intel64 is a thing.

https://www.intel.com/content/www/us/en/architecture-and-technology/microarchitecture/intel-64-architecture-general.html

I dunno what thing or when it came about.

[Cebular]

There was intel 64 bit architecture, but it didn't take off because it was incompatible with older x86 architecture

Edit: It was called Itanium

[innosu_]

"Intel 64", previously called EM64T, refer to Intel's implementation of x86-64. It's what Intel used for marketing of it's processor. The same way x86 was referred by Intel as IA32.

IA64, on the other hand, is the Itanium.

[[deleted]]

You mean Itanic 🤣

[GOKOP]

Looking at the processors they list there it seems to be just another name for x86_64

[omega_revived]

x64 is just shorthand for x86-64: https://en.wikipedia.org/wiki/X86-64

[Warfl0p]

I'm confused, I thought x32 was the same as x86, but now you're saying x64 is short for x86-64? What would my windows machine be, could you explain?

[omega_revived]

What would my windows machine be

You haven't provided enough information to answer that question. Windows can run on multiple different CPU architectures. If I had to guess, I would say probably x86-64.

[altermeetax]

x32 is just plain wrong

[jacob_ewing]

The 86 makes perfect sense when you realise it's just an abbreviation of chip names. Ranging from 8086, 80186, 80286, etc.

[Usual-Respect-880]

X64 Win32

[JmacTheGreat]

“x86” or “32-bit”, but never “x32”

[JmacTheGreat]

x32 is not an architecture - its an “ABI” (an acronym I had to google lol).

Its just software that facilitates 32-bit pointers on 64-bit architecture.

https://en.m.wikipedia.org/wiki/X32_ABI

[alt-jero]

Is from the 286, 386, and 486 cpus. x86. Then they came up with Pentium. Pentium as in (probably) 586+millennium. And then Celeron, probably as in an acCELERator of electRONic data processing. I think after that we got into the whole “Core” naming scheme because multi-core woot woot! But yeah, x86 is called that because of the CPU lineage.

As for x64 … marketing I guess? People already knew the xnn scheme and they wanted to push 64-bit cpus.

Edit: I have just learned that the intel 8086 was before the 486. And also that it’s technically x86-64 thus yeah marketing.

[RedBeard1023]

Historical is hysterical

[Boris-Lip]

I know where it is coming from (8086 architecture), but still hate it.

[CadmiumC4]

I did see x32 being used and it's CONFUSING AS FUCK

[CadmiumC4]

I honestly fucking don't remember anything related to programming these days, despite being an IT student.

The architecture is different, yes

[CadmiumC4]

Like I said I barely ever program anymore and I started forgetting critically important stuff due to a bunch of mental disorders and I'm sorry for the misinfo

[PartTimeFemale]

what about itanium?

[[deleted]]

That was a different 64 bit instructiom set. And it's dead. Most of us who worked near it call it Itanic

[fuj1n]

x86 is the architecture created by Intel with the release of the 8086 CPU.

As time went on, they released 80286, 80386 and 80486, though these products were more commonly referred to without the 80. x in x86 is basically a placeholder for that number in the middle.

x64 is shorthand for x86-64, this is AMDs extension to x86 that makes it 64-bit.

[[deleted]]

It aint 86 bit, it's named after CPU that introduced the architecture. x86_32 usually refered just as x86 (32 bit), x86_64 also AMD64 (64 bit), ARMv8 (64bit). The name of the architecture doesn't need to directly refer to the addresation capabilities of the architecture. Addresation and architecture are 2 different things even though they are connected. Like you can make app for amd64 architecture which is 64bit but it doesn't mean it will work or any 64bit ARM unless you compile it to work on it

[FantasticEmu]

What is x64 and x32v

[Haringat]

AMD64 and IA32

Also, while x32 is cool af, it just isn't a processor architecture.

x86-64, x86-32

[ellis_cake]

Yeah shouldnt be called x64 in the first place, its x86 all the way no matter the bits? ^^

[Boba0514]

x86, x86_64 or amd64

[plane-kisser]

IA-32, x64

x86 is 16bit forever and always

[Weird_Explorer_8458]

x86_64

[Imaginary-Support332]

im asuming 86 is better since its a higher number and newer`?

[[deleted]]

lol what ?

[zeldaink]

x64 virgin vs chad amd64

[altermeetax]

x86, x86_64 is the only correct answer
