qubit'tis nothing, don't make such a big deal out of it! This patch simply puts everyone on a level playing field to make things fair.

#intelapologiststrikesagain

LOL, nice one.

RejZoRAny penalty sucks, even if just 5%. You bought the CPU based on reviews that said otherwise. And now it'll get gimped.

Here's the thing. Datacenters don't buy CPUs based on reviews. :)
In fact most PC owners don't look at reviews, nor would they understand them. Even many gamers don't.

Yes, this is an important issue, but many of you are overestimating it's importance for the whole market.
I mean: isn't the main argument of Intel critics that they only provide 5% with each generation? That it's nothing, marginal, irrelevant? That Kaby Lake is just a revamped Haswell or something?
So now we have a CPU design flaw that, on average, moves us a generation back. Why is it suddenly such a deal for the same people? :)

I like the +5% yearly, so I should be pissed off when it's taken away from me. And I might be, but I'm waiting for the patch. We'll see what it does to my PC. Possibly (hopefully) not much.

eidairaman1Well it is a serious flaw that Intel has @notb. What's the matter don't like the fact your precious intel has the issue and they are so corrupt to try and force a patch for ms to auto download on w10 systems?

Of course it's a serious flaw, But there is a difference between 5% and 30% - all I'm saying. If it's 5%, most people won't even notice.

BTW:
Bullseye on auto-update. I have nothing against it. Actually, since I moved to W10 on all my PCs, I stopped worrying about the updates, I stopped reading their descriptions and so on. It saves a lot of time. You're thinking less about technical issues and more about actual problems. It's like moving from C++ to C# (although C++ evolved anyway).

Think about how incoherent people are. Almost no one cares about how a new OS version differs from the previous one. Yet, so many people freak out about updates.
I know it slightly harms your ego, because you're "an enthusiast", you want to have control over your PC and so on. But productivity-wise, it really saves a lot of time. I'm trusting a 3rd party cleaning company with my suits, so why would I not trust Microsoft or Intel with my PC? :)

theoneandonlymrkIs this just affecting the performance of vm's using the linux kernal??

No, it will affect all PCs. But the issue itself is more severe on servers. (security-wise).
But here's some consolation, in case you worry too much. Performance of your desktop is compromised by server-specific needs anyway. It's been like that since the architectures were unified. :)

Im not worried i can refuse the patch but don't play down the fact intels CPU design this last few generations has been a shit storm of failure on the security front or the fact that it's underhanded bullshit to apply this fix unilaterally.

Admins of data centers also know the performance metrics. Having a performance penalty of up to 30% on Intel CPU kinda screws things up pretty badly. Especially if you just spent few millions on brand new clusters where you were hoping for that extra gain and you basically end up on performance levels of your old clusters. That kinda sucks doesn't it?

Exactly. You have to understand that within DC's there are clusters of Intel based CPU's running 24/7. A penalty of 5% up to 30% can run very large into numbers depending on type of workload. So yeah, intel is having a situation here.

I smell class action for misrepresenting and allowing a flawed product line dating to 2007 till now to be pushed upon end users.

RejZoRAdmins of data centers also know the performance metrics.

But not from reviews. :-)
Performance is not the most important issue in datacenters. So yes, 5% is a bummer, but it's also not the end of the world. People will still buy Xeons. It's just that Intel may be forced to lower prices a bit to a more adequate level.

No one said it doesn't suck. And BTW: from what I've seen it's at least up to 50%. So if you want to use an extreme case, do it properly. :-)

No, 25-30% is then a good average if 50% is an absolute extreme case...

RejZoRNo, 25-30% is then a good average if 50% is an absolute extreme case...

Either way it is unacceptable

Except datacenters get a 30% performance decrease! MAJOR companies suddenly will have 30% slower cloud servers!!!!! That's going to piss them off for sure!!!!

eidairaman1I smell class action for misrepresenting and allowing a flawed product line dating to 2007 till now to be pushed upon end users.

Class action seems groundless. It's a product fault, not misrepresenting, and Intel is going to fix it as much as it can.
But on the other hand, fixing this will generate some costs in large datacenters and this is something with a lawsuit potential - but only for companies that still use flawed CPUs, not all that had since 2007.

RejZoRNo, 25-30% is then a good average if 50% is an absolute extreme case...

That's some wicked math going on. How did you estimate this? :-D

ALL the CPU's from Intel the last ten years have the flaw!!!! Some of the most powerful supercomputers can be slowed down by 30%!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The most basic math? If 5% is lowest estimate and 50% the highest, where is the rough middle?

There is no fixing it without refabing the chips, otherwise it's a patch that drops performance 5-30% and they are trying to force it on all users when the flaw isn't in AMD parts. Stop trying to minimize and deflect the issue.

The Jig is up, just give up dude.

hellrazorLinux has a -nopti kernel boot option for us Linux+AMD users.

How does one go about using it?

Though i'm now more familiar with Linux, this sort of thing is still out of my reach.

theGryphonFor advanced Linux users, there is no concern, you can even compile your own kernel excluding your system from this patch. But most are not that advanced, so this is some serious BS if left like this. I'm hoping that this is a one-for-all emergency response that can be rectified once AMD processors are (hopefully) cleared after some investigation...

They better well be. When that happens, i'd demand a nice compensation, if i were in AMD's shoes!

I'm beginning to wonder if this serious enough to warrant a product recall and replacement with a later stepping that has this flaw fixed? Waddya think, @eidairaman1 ?

It will cost them millions of that's the case, lol.

Depends on how long they've known about this, or were informed about it. Like I said in the other thread, this flaw was possibly revelead back in 2016, so if somehow it went unpatched & Intel/MS/Linus just sat on it till they found the attack vector affecting systems in the wild & then issued this emergency patch, then they're all in trouble. More so the cloud vendors than Intel itself atm, of course someone like Google/FB/Amazon could just sue Intel if there's any litigation coming their way due to this, or even a performance impact due to that 5~30% (or more) drop in performance.

I'm more interested in how old(er) OS' can be affected by it, if so then Intel's really effed o_O

Hugh MungusALL the CPU's from Intel the last ten years have the flaw!!!! Some of the most powerful supercomputers can be slowed down by 30%!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The number of "!" is growing quickly!

Since this is a security issue, most supercomputers will be perfectly safe. Admins will simply ignore this patch. Linux kernels in supercomputers are highly customized anyway.
This is an issue for datacenters.

What I meant is that you'd have to use a faulty CPU at the moment, not just have owned it in the past. So it's not about all CPUs made since 2007. You won't be able to sue Intel for a CPU that you've thrown away, because you haven't lost anything.

Please don't tempt me...

sorry mate for someone thats a 2nd rate tr**l you seem to ignore 1st rate reason for a class action ie faulty product (with known but undisclosed till now fault)

Intel has been trying to hide these flaws for 10+years now.

I think they should be required to replace all of those parts corps bought recently and pull all affected parts from markets till the flaws are eliminated, on top of that give discounts to users of oldest parts towards system upgrades to parts without flaws and close up all backdoors. Release said patch for intel only temporarily and not force it on everyone.

I think this is a part of the reason why Intel switched CEOs recently

dorsetknobsorry mate for someone thats a 2nd rate tr**l you seem to ignore 1st rate reason for a class action ie faulty product (with known but undisclosed till now fault)

Yup

Can't wait to see Intel releasing new generation and bragging about % performance differences to these flawed gen patched parts...
