45% reduction post-patch!

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.

Seems CPUs without PCID are really fucked.

>mfw glorious Threadripper is not affected
>mfw 98% percentile on stock settings

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

>You?
i switched to AMD in 2006

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.

Teehee. That sweet sweet Karma Intel.

Lollllll

I'm wouldn't be surprised if the windows patch will hit older gens a lot harder then more recent ones.

Is the patch in the arch rops yet?
what version of linux is considered fixed and safe

What is pcid how do I know if I have it

>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.

It's time to get a new laptop, so... it's going o be AMD right?

I have a 6700k, how fucked am I

Are you using your computer for just for watching movies and browsing the internet?
If yes, then you are cool.

you are about this fucked:
not fucked [..............::.] fucked

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.

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.

>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.

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.

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

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.

>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

lol nerd

>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.

a nerd on Sup Forums? unacceptable!

Does Win7 support it?

4.14.11 has the patch against Meltdown

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?

Fuck I'm thinking of getting some powerpc and installing something like fucking BeOS

here's mine pre/post

what the fuck cpu do you have?

Fake

...

What happened? Will my i5 4460 get affected?

yes

THIS CAN'T BE HAPPENING! This is AMD's smear campaign!

>98 percent percentile
????

Wow

Literally doesn't happen on my system, heh.

fuck me, this thing is barely fast enough for me, i cant afford a 45% performance hit

...

does it run hotter?

>April 1st 2018

>Currently January 4th 2018

get fucked eurofag

...

Its a cheap laptop so I've never cared about thermals and have no answer to that.

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.

why are people so tight lipped about their CPU models?

Been trying to get my wife to upgrade her laptop for a while now. This will probably force her hand.

6700k

come at me bro

because you have AMD

What will the affect be on laptop battery life?

macOS 10.13.2 - was apples fix. Here are some complaints
reddit.com/r/MacOS/comments/7j9qlm/10132_killed_my_battery/?st=jc0qdubn&sh=db711d8d

NOOOOOOOOOOO

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?

>45% performance hit on my 2007 low voltage core 2 duo qt laptop
AAAAAAAAAAAAAAAAAAAAAAAA

You can just download coreinfo and run it on cmd

just check your fucking cpuid idiot

must be nice to have atom tier performance

How far back does this go? Are c2d machines safe

Anything older than Pentium II is fine.

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.

People who notice no performance hit havn't enabled the fix in settings.

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.

>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.

That's the point my man.

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.

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.

kill yourself, degenerate weeb

Some numbers from an Intel engineer taking on early Meltdown patches.

lwn.net/Articles/737940/

>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.

So PCID just mitigates the meltdown. All needs to be replaced ASAP.

The chaos and fallout from this hasn't even started yet. It's going to be an interesting few months.

can anyone on the fast ring can provide more proof?

How is the performance hit on 1st Gen Core i5?

the patch is opt in so most normies wont have it enabled even if its installed.

So what's happening is critical internet infrastructure and services patched yet and up running? They must be completely FUCKED if they are, surely?

How hard will this fuck my i5 4670?
Will it be noticeable while playing games?

I have a 4670k. Haswell.

How fucked am I?
Should I just bite the bullet and get a Ryzen 5?

Read some threads for fuck's sake. Gaming isn't affected as much as other tasks.

...

Here are my specs.

Believe me or not, makes no difference to me.

The patch you're talking is the OS patch or the Intel patch?

And linux performance are being very affected as windows?

I haven't noticed any performance impact at all.


Because there's no patch for windows 7 yet.

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?

pretty sure it's an opt out, not in

They made it opt-in because the windows patch is incompatible with some antivirus programs

Yes. The new Ryzen U mobile APUs shit all over current Intel 4 core U parts.

Probably because sensitive infastructure might run on nigger rigged home servers and a 42% drop in performance could kill people.

>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.

Realistically how big of a deal is this whole meltdown thing for the average joe?

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.

Skylake and onward have cpuid

How do I remove all stored passwords from my computer

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.

6700 eh
twitter.com/grsecurity/status/948170302286172160

lol

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.

W.e my point is skylake and ownward take less of a hit

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.

It's opt in for Windows server users. Not for regular dumb consumers.

HAHA WHAT

ITS OVER

THE CRYPTOCURRENCY MEME IS OVER

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

>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?

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.
