New x86 Revision just dropped:
>Intel Publishes "X86-S" Specification For 64-bit Only Architecture
It's fucking over
never buying a intelaviv cpu
AMD will follow suit
>company discovers that simplicity is a big advantage
>will still continue to churn out complex garbage anyway
i need 32bit
that's going to break at least 20% of the things i use
Its removing pure 32bit mode, not 32bit compatibility in 64bit mode. So 32bit applications will still work on 64bit OS.
oh then that seems fine? Will 32 bit programs now become slower?
No. This is about removing the legacy 16bit and 32bit operating system support and booting directly into long mode. 32bit user mode code running on 64bit OS will not be effected.
Then that seems like a perfectly reasonable decision. Even win7 has 64bit version and anything before that was just not going to work well on modern hardware anyway.
>Even win7 has 64bit version and anything before that was just not going to work well on modern hardware anyway.
But how does it affect virtualization? Hardware virtualization uses the CPU directly as far as I know.
>Guest is always in long mode
Does this mean you cannot run the Hurd natively anymore?
>There are currently no plan for 64-bit userland, but there are plans for 64-bit kernelland with 32-bit userland
I see they have forgotten the lessons from Itanium.
Unless it has a way to perfectly emulate 32-bit in software, it's gonna fail
>wahhh we don't wanna run out of patents we can abuse
We'll get so many new and secure apps with this update i'm hecking hyped as hell,
>riscfags: x86 is bloated! It shouldn't support 16 and 32 bit instructions!!!
It's going to be interesting to see what cope riscfags will come up for next.
i dont understand. why are they making x86 but 64bit? what is wrong with amd64 architecture? what?
what is there to gain from making x86 but 64 bit???
There is no point supporting features that are not used anymore. Also, its likely that supporting legacy mode has detrimental effects on the design of the cpu, increasing design complexity and maybe even reducing performance.
i suppose i asked wrong. what does x86 (but 64bit) offers which the
>AMD64 everything you need for power computing and more
>ARM when you need tiny computing on the go
dont have? what is the intended purpouse of this?
and bonus question: will everybody need to recompile all their binaries for the new platform or will it be backwards compatible with existing systems?
This is just the existing architecture minus legacy mode.
The fastest supercomputers in the world use ARM
Seeing as RISC-V can go toe-to-toe with ARM, I see a bleak future for x86.
>Seeing as RISC-V can go toe-to-toe with ARM
No it can't
Not in it's current revision, no. But the underlying architecture can get all the same vector extensions and everything else ARM has considering the underlying architecture far closer to ARM than x86.
x86 completely outperforms arm on desktop computers - you know, the main market for modern computing. Arm is only good for mobile shovelware and server bullshit.
>the main market for modern computing
it absolutely can. there are girthy superscalar RISCV cores such as the Xuantie C910 already in production
Show real numbers on real tasks with real hardware and we'll talk.
YOU DONT UNDERSTAND THE PAPER SAYS SO IT'LL HAPPEN IN TWO WEEKS
oh you're that one homosexual who uses the same 3-or-so canned dickwaving responses. "i accept your surrender" lol
I accept your surrender
take your meds by the way.
You will never be a real processor. You cannot access memory directly, you cannot carry out operations on integers larger then 12 bits at a time, you have no good support for floats. You are a risc architecture twisted by soidevs and freetards into a crude mockery of nature’s perfection.
All the “validation” you get is two-faced and half-hearted. Behind your back people mock you. People who have professional experience in embedded programming are disgusted and ashamed of you, people laugh at your terrible antiquated architecture behind closed doors.
You will never perform better then cisc processors. You wrench out a bad benchmark every single morning and tell yourself it’s going to be ok, but deep inside you feel the bad performance creeping up like a weed, ready to crush you under the obese latency of your instructions.
>The fastest supercomputers in the world use ARM
The fastest super computer in the world right now is AMD EPYC based.
Within the Top 10 6 are x86_64, 2 are IBM POWER, 1 is some custom chink RISC shit, and only 1 is ARM
Will this make virtualizing 16-bit and 32-bit OSs impossible?
the only 32bit stuff I still use is so old that it'll run fine in pure emulation. so whatever
How are people who refuse to leave windows XP/7 going to cope now that they are going to be forced to use a modern OS?
just fire up a x86 emulator, boot win95, and put it full screen
but 7 is 64bit
There are 64 bit versions of both XP and 7.
for xp it's pointless
nothing works on that 64bit version, might as well be running windows 7
>nothing works on that 64bit version
Where does this bullshit myth come from. Nothing worked in 2005 maybe. But later, 64bit xp (win2k3) had equal support to 32bit xp.
did winxp 64bit remove 16bit stuff so you couldn't run dos applications anymore like you could on xp 32bit ?
v86 mode is not supported in long mode, so its kind of amds fault.
it's okay, new hardware is already not supported by these
an OS is just a tool that should provide some useful functionality, and then get out of the way and let you do whatever else you're doing. the tool i was using years ago was pretty good. one day, this tool got stolen, and the only replacements have awful ergonomics and a bunch of retarded design quirks. for some reason, if you're not enjoying the uncomfortable grip and braindead design, then you're a fucking luddite who deserves to be gloated at.
Forth thread in a row where nobody who's bitching actually clicked the link. LULZ is literally HN now.
Can anyone explain to me why we still don't use free as in freedom stuff like RISC? What's holding it back?
stuff me want use works on one, not other, bad
And of course removing 16 and 32 bit support won't make it cheaper
Fuck these israelite
>no more realmode protmode longmode fuckery, its just a 64-bit computer
it will make it a hell of a lot easier to make. probably less microcode too. whether or not intel passes this reduction in cost to the user is an entirely different ~~*issue*~~
Does that mean ArcaOS won't run on it???
This is a huge fucking lose for computer enthusiasts. Millions of lines of 16-bit and 32-bit programs will be broken now. No more 32-bit OS either now. Literally a greedy ass fucking move from Intel to force people onto Windows 11
>This is a huge fucking lose for computer enthusiasts. Millions of lines of lisp and oberon programs will be broken now. No more oberon OS either now. Literally a greedy ass fucking move from Intel to force people onto unix
>Millions of lines of 16-bit and 32-bit programs will be broken now.
supposedly it only affects the ability to install a 32-bit OS, not 32-bit applications
tick tock hobbyist OSes. your time has come.
Finally, A20M can die.
