Will you apply patches, Sup Forums? I'm thinking about selling my mobo + CPU ASAP while they're still worth something and getting something that's unaffected by this shit. Either that or not applying patches at all and just living on the edge. You?
Anyway, 45% reduction is fucking insane. And I bet all the page swapping will make the CPU run hot too.
You can't be serious about considering NOT patching this huge vulnerability, are you?
It's not like gaming will be any better when you have to air-gap your shit.
Oliver Baker
Teehee. That sweet sweet Karma Intel.
Lollllll
Samuel Gonzalez
I'm wouldn't be surprised if the windows patch will hit older gens a lot harder then more recent ones.
Adam Hill
Is the patch in the arch rops yet? what version of linux is considered fixed and safe
Carson Smith
What is pcid how do I know if I have it
Jack Morales
>what version of linux is considered fixed and safe Any recent version with a secure CPU.
There's no safe Linux version on defunct hardware.
Evan Carter
It's time to get a new laptop, so... it's going o be AMD right?
Carter Scott
I have a 6700k, how fucked am I
Lucas Lewis
Are you using your computer for just for watching movies and browsing the internet? If yes, then you are cool.
Colton Kelly
you are about this fucked: not fucked [..............::.] fucked
Gabriel Cox
Well, let's wait until the embargo is lifted but since their is such a thing as an embargo I'd expect you to be very fucked.
Samuel Butler
Skylake should have PCID support so you're slightly less fucked on the performance side than if you had an earlier chip. That is, if your OS supports it.
Brandon Watson
>browsing the internet This is the one thing you shouldn't do with Intel CPUs now.
You will deny this because it sounds ridicule and inconvenient at least but you know it's true.
Blake Walker
It's a good thing my PC is already getting somewhat old with that 4460, but I can't trust AMD not to get fucked by something similar in the future.
Dominic Green
This is indeed the issue we have nowadays with closed source hardware. I dream of a world were we compile out own soft-cores for fpga based PC's
Liam Flores
>You can't be serious about considering NOT patching this huge vulnerability, are you? > >It's not like gaming will be any better when you have to air-gap your shit. I only worry about the browser since it's the only real attack surface on my machine that runs code from the internet.
Firefox 57 has removed shared array buffers and has reduced timings for all processes. That severely reduces or makes attacks through the browser possible.
So I don't see a point in applying a patch that reduces performance by 45% right now.
Robert Morgan
>Are you using your computer for just for watching movies and browsing the internet? multiple vps, multiple w7 vms for everything from web browsing to random porn sites to playing the occasional game, firewall, file server, router, video transcoding, and heavy file compression of archives in the XXXGB size with single files being upwards of 20-60gb or more.
so from my understanding operating systems are going to get a patch to deal with this shit. When can I expect an update from linux? I checked the change log for 4.14.11 and there is some mention of this but I dont know what it means. It sounded like it was patched but then it also sounds like its not
Ian Stewart
lol nerd
Ayden Price
>I only worry about the browser since it's the only real attack surface on my machine that runs code from the internet.
Sweetie, ALL the code you run comes from the internet...
>So I don't see a point in applying a patch that reduces performance by 45% right now. The performance reduction is only a by-product of not having a completely wide open internet connect PC. The point is to not be extorted or profiled.
Jacob Ortiz
a nerd on Sup Forums? unacceptable!
Evan Taylor
Does Win7 support it?
Julian Scott
4.14.11 has the patch against Meltdown
Eli Baker
cool. Is there other shit that is a threat right now? what isnt patched that is an issue for me? I thought meltdown was the meme name for this. Ive seen the term spectre, is that part of melt down?
Dominic Gutierrez
Fuck I'm thinking of getting some powerpc and installing something like fucking BeOS
Eli Diaz
here's mine pre/post
what the fuck cpu do you have?
Ian Morris
Fake
Julian Flores
...
Robert Murphy
What happened? Will my i5 4460 get affected?
Asher Price
yes
Cooper Richardson
THIS CAN'T BE HAPPENING! This is AMD's smear campaign!
Alexander Price
>98 percent percentile ????
Joshua Ross
Wow
Easton Reyes
Literally doesn't happen on my system, heh.
Dominic Cooper
fuck me, this thing is barely fast enough for me, i cant afford a 45% performance hit
Juan Cruz
...
Thomas Myers
does it run hotter?
Logan Allen

Gavin Clark
Its a cheap laptop so I've never cared about thermals and have no answer to that.
Xavier Gutierrez
Fake as fuck. Why the hell would integer math be fucked that much? It's not like you need to context switch to do that shit.
Camden Jenkins
why are people so tight lipped about their CPU models?
Alexander Cook
Been trying to get my wife to upgrade her laptop for a while now. This will probably force her hand.
I'm also on the i7-6700K. Can anyone confirm if this CPU supports PCID on Windows 10 and if similar perfomance hits will be mitigated on this hardware compared to legacy shit?
Ryan Butler
>45% performance hit on my 2007 low voltage core 2 duo qt laptop AAAAAAAAAAAAAAAAAAAAAAAA
Ryan Nelson
You can just download coreinfo and run it on cmd
Thomas Jenkins
just check your fucking cpuid idiot
Anthony Lopez
must be nice to have atom tier performance
Jonathan Bailey
How far back does this go? Are c2d machines safe
Andrew Taylor
Anything older than Pentium II is fine.
Jack Martin
Actually i think it's worse than an Atom but it browses internet, plays old games and handles 1080p30 so it's fine by me.
Sadly all "modern" laptops are a downgrade in everything but specs.
Christopher Richardson
People who notice no performance hit havn't enabled the fix in settings.
Jose Lopez
I've got two of these but haven't run any benchmarks. Are we getting hit that hard? Fucking hell. I'm going to have to air gap one of them and not install any more updates.
Anyone else with Core 2 Duo Thinkpads I'd be very interested to hear your experiences post-patch.
Carson Howard
>all within margins of error >no mention of which cpu make & model I don't believe you. If fact I'd bet you just ran the same test twice without any changes.
Justin Lewis
That's the point my man.
Ryder Allen
I'm assuming an asterix means I'm good to go with PCID support? I don't know how to do that, I'm legit retarded.
Kayden Gutierrez
I manualy downloaded an update from MS's catalog and installed it. After that the detection script looks like this. Can someone translate it to normal human language? Am I safe? I'm on Sandy Bridge btw.
Aiden Ward
kill yourself, degenerate weeb
Gabriel Allen
Some numbers from an Intel engineer taking on early Meltdown patches.
>It's a pretty quick syscall so this shows how much KAISER slows down syscalls (and how much PCIDs help). >The units here are lseeks/second:
no kaiser: 5.2M kaiser+pcid: 3.0M (-42%) kaiser+nopcid: 2.2M (-57%)
These being syscalls only, imagine interrupt handling getting a massive slowdown as well for real world server loads. Datacenters are completely fucked, older ones without PCID... RIP.
John Cooper
So PCID just mitigates the meltdown. All needs to be replaced ASAP.
Kayden Johnson
The chaos and fallout from this hasn't even started yet. It's going to be an interesting few months.
Michael King
can anyone on the fast ring can provide more proof?
Leo Moore
How is the performance hit on 1st Gen Core i5?
Connor Evans
the patch is opt in so most normies wont have it enabled even if its installed.
Liam Jackson
So what's happening is critical internet infrastructure and services patched yet and up running? They must be completely FUCKED if they are, surely?
Aaron White
How hard will this fuck my i5 4670? Will it be noticeable while playing games?
Hunter Roberts
I have a 4670k. Haswell.
How fucked am I? Should I just bite the bullet and get a Ryzen 5?
Josiah Diaz
Read some threads for fuck's sake. Gaming isn't affected as much as other tasks.
Dylan Diaz
...
Cameron Price
Here are my specs.
Believe me or not, makes no difference to me.
Cameron Edwards
The patch you're talking is the OS patch or the Intel patch?
And linux performance are being very affected as windows?
Jacob Ross
I haven't noticed any performance impact at all.
Because there's no patch for windows 7 yet.
Jacob Smith
Why would something so critical that it gets media fan fare and it's own websites describing how bad it is.. be an Opt-in option to fix?
Leo Davis
pretty sure it's an opt out, not in
Luke Mitchell
They made it opt-in because the windows patch is incompatible with some antivirus programs
Kayden Roberts
Yes. The new Ryzen U mobile APUs shit all over current Intel 4 core U parts.
Justin Foster
Probably because sensitive infastructure might run on nigger rigged home servers and a 42% drop in performance could kill people.
Bentley Stewart
>And linux performance are being very affected as windows? System calls and interrupt service routines are fundamentals on which all modern OSes are built. Meltdown being a hardware problem requires a workaround that is very low level as well. Overhead is going to be huge no matter what.
Nathan Wilson
Realistically how big of a deal is this whole meltdown thing for the average joe?
Blake Sanders
For all practical purposes it only affects servers and server workloads, considering the patch is for a security oversight that is primarily a concern in the server space anyway, I think you can see where this is going. You can even not install the patch if you don't want to, if you feel that the performance is more worth it to you than the vague off chance that a specific virus on your system might steal your passwords to your favorite asian sex slave outlet.
Owen Barnes
Skylake and onward have cpuid
Colton Murphy
How do I remove all stored passwords from my computer
Hudson Myers
Potentially fucking enormous if a quarter of internet services go bankrupt and another half seriously struggles under the increased work load. The environmental ramifications won't be very desirable either.
Wait, if it's opt in, does that mean all the posts we're seeing with no perf hit are because it's not even enabled?
PCID is not cpuid, as far as I understand, the later being available since 2000 or so.
Levi Davis
W.e my point is skylake and ownward take less of a hit
Evan Collins
I do crypto mining, so I think this will affect my bottom line. Having the security hole is probably bad too, since it would allow someone to duplicate my hashes in real time and steal my work without having the hardware.
Sebastian Young
It's opt in for Windows server users. Not for regular dumb consumers.
David Taylor
HAHA WHAT
ITS OVER
THE CRYPTOCURRENCY MEME IS OVER
Angel Morales
Yeah of course tons of internet services are going to start running like ass but I mean for the average guy himself. Like, it's not like suddenly a billion computers will get infected by a thousand viruses and everyone will have their lives ruined by evil russian hackers
Jack Adams
>have i7 3770k >installed KB4056892 >passmark before and after gives me no change in performance / within margin of error
did i get lucky? or am i just retarded, both?
Sebastian Evans
Considering there are mining-specifc boards that have a like a dozen x1 slots for cards, I don't think the CPU itself has much to do in mining workloads, since apparently the bare minimum of a PCI-E connection doesn't bottleneck the results.
