*NEW* HyperThreading doesn't matter! (again)

By the time zen2 ships intel cpus will look like Swiss cheese.

This is NOT limited to hyperthreading CPUs.

Why the fuck do people make logos for vulnerabilities..?
Caleb Brown
Why? Because Intel can screw it up faster than you can screw it up hard.
But that's not all there is to it. Even if the code is buggy, all the code needs to be done. If you know how to compile the binaries correctly to run the test suite in an emulator for real then you can build your own.
The reason not to do all of this? Because the compiler is not always reliable. And if your compiler/test software is unstable then you will still need to deal with the problem of the compiler being buggy as you don't have it set as stable. In order for an app to compile to the correct code then it needs to be stable on the platform. If your compiler gets buggy then what happens to your app? Because then you have to start over from the beginning. A single bug in the compiler will probably cost you $200 from the time your app is released. So, if you are building the app on your own you probably better get the help of some guy (or gal) handy to help you out in case something is messed up in your program.

I assume because managers do not give a shit about them unless they have a catchy name and logo. Also, it's easier to say RIDL than CVE-2018-12130.
Robert Walker
What's up with the schizoposting lately? Is this some fancy new botnet C&C mechanism?
Adrian Brown
Didnt patching patching out spectre cause a 20% performance hit? And meltdown another 13%? And now like three more that are going to be 8-9% each?
At this point some of these things must be running at like half their launch speed? Thats a problem
Jace Foster
Apple claims 40% from disabling HT. I assume the impact will be much lower on non-HT chips.
Dylan Ortiz
Yes. It's not something we're proud of yet. We're still building our own tools that are designed not just to deal with this particular problem, but to solve it in the very near future... So, we're not afraid of building new tools on top of this. When the community demands new, more efficient and user friendly tools, we are happy to build those tools. At the same time, if developers don't want to wait for us to build their own tools, they don't really need to. We've been working for three years now to make sure we get a good API for the botnets, so there should be very little friction.
But if there isn't a good API there, what will I do? I have a couple of ideas...
It's a great question. It doesn't appear that anyone really knows what's causing it. There's always speculation as to what causes botnets to run, and it could come from any of the many forms of internet activity you've described.

Some of the posts resemble botposting through openai.

oof

My amd mobo and threadripper get closer by the day

The Windows 10 update that fixes this appears to be KB4494441. I am currently being railroaded into version 1809 (as an Enterprise "customer" on the Semi-Annual Channel) and will report back once Windows Update finishes fucking me over.
Blake Murphy
they already look like swiss cheese, two whole years on this shit non stop
Jordan Bell
Suddenly I'm glad to be a poorfag and going with a Ryzen 5
Anthony Peterson
Ubuntu and IBM® Red Hat® Enterprise Linux™ are deploying fixes.
Fedora, Debian and Arch do not appear to have fixes out at the moment.
Please update ASAP, my fellow brain-dead Intel buyers. :DD
Joseph Cooper
How do they do it?
Nathan Wilson
No, intel hyperthreading was always fucked, and it's only now that anyone is finding out.
Robert Harris
So does nobody actually care about this?
Justin Jenkins
Who gives a shit about hardware "vulnerabilities", just update your OS and use common sense when opening links
Julian Powell
Joke's on Intel because my OpenBSD disables hyperthreading on boot.
Julian Sullivan
This doesn't change my position to never buy intel processors. Try warning people about intel(ligence) inside but are they going to care.
Lucas Fisher

Mason Parker
I imagine Amazon, Microsoft, and other large companies selling cloud services give a massive shit over this one. The performance drops from security mitigations really add up.

Joseph Butler
Now the 9900k is useless compared for a 9700k
Grayson Myers
pretty sure they are on 8th gen+ and have decent enough security on a software level
Jacob Gomez
You have more threads than a 9700k
Zachary Turner
As mentioned slightly below the OP post, you are affected by at least one of these MDS vulnerabilities even if hyperthreading is disabled. You need to install Intel's patch. I'm not sure what OpenBSD's stance towards microcode patches is, though...
Austin Cruz
wow, i'm stuck on intel cause poor and can't upgrade but man, never again.
>trusting jews
>ever
Noah Brown
as the picture says, just don't run untrusted software. also
>hyperthreading
>+40% performance
lmao

>untrusted software
like, for instance, the javascript on Jow Forums.org?

My 6700k keeps getting slower and slower. Fuck. Zen 2 save my ass.

that's OK, not a facebook drone
Colton Anderson
you are a special kid, aren't you? do you think they really enjoy having to waste 1.5 times as much power while providing services for same price? retard

>tfw you just bought an e3 1280 v2 a few months ago
this was supposed to last me another 5 years!
Samuel Martinez
Sell it

>quad core lasting you 5 years
Nigger, AMD has cheap 8 cores out. This is all your fault.

so I should update and disable hyperthreading on my old laptop i7 2670QM?
Leo Reyes
This CVE never had PoC code
John Hall
share source code?
