Intel bug incoming? Meltdown and Spectre exploits

[mattyfez]

Many forms of hype train.

The share prices changing doesn't mean AMD has more cash in pocket but it means investors in Intel are scared it might affect the bottom line.

Well that's what the stock market is.. Pure hype. If you check now, the share prices have settled right down, Intel are down a bit and AMD are up a bit.

AMD 5.1% up
Intel 3.5% down

That's still a significant change.

AMD have done very nicely out of this.

They think the issue is not unique to them, not sure what this means yet.

It's not unique to Intel, but what they carefully avoided saying in that statement is that the patch to fix it does not hit performance on AMD systems, whereas is does hit performance on Intel systems in cloud /data centers.

I saw that Linux kernel submission earlier. It's interesting that at the bottom it shows the diff between their submisison and the prevoius version. So there is a version out there which assumes that all CPU's are affected. So the first patch might also hit AMD until a second patch is released. I'm sure this will be released quickly under Linux since we can see that the patch has been submitted by AMD themselves. But how quickly for Windows since only MS have control over it?

Already pulled into the kernel tree , Linus himself did it

Edit :
Wasn't Linus it was another maintainer that pulled it into here the tip/tip.git tree

Yes it does hit amd perf wise but the patch/fix is not needed on AMD CPU's thus irrelevant

This news made my mind up for me, just ordered the AMD 1800x

 

[jabbz]

I know how Intel can fix this problem, just use glue to put them back togeather hahahaha!!!
AMD if you read this, you are welcome to use this one. I'm sure they will not mind as they said it first

 

[pete910]

Phoronix guy is delving deeper in

Looks to be doing some extensive testing too, seems apt as its more server perf that's the worry here not so much average joe desktop.

The more recent PCID capable Intel CPUs are less affected by the patch. Do we have firm ideas on what the exact slowdown (if any) will be?

Oooh, some nasty politics and water muddying going on there. Making sure to use competitors names in the same bad news release, dirty moves by intel- they look very worried to me......

They'd have patched it long ago if they knew, they are now down 6%, I don't know what that is in USD, but it's a freaking lot, plus the reputational damage.. That's a big gamble to take to punt a few more CPU's especially as AMD haven't been remotely competitive for the last ten years.

It's not like they didn't know their own processors were processing code insecurely. It had to have been done on purpose and it would have been to keep a performance edge over rivals. They did a VW basically (cheated and kept it quiet). Hackers would have definitely known about it as well.

What a mess really. Very VW alike.

 

[Randomface74]

So should we all be assuming our machines are already compromised and reinstalling Windows?

In what way exactly?

Installing Windows 10 is the compromise so knock yourself out.

. . . [Intel] did a VW basically (cheated and kept it quiet) . . .

Seems harsh and pure speculation.

In order to compete in the US market, VW deliberately included code in their diesel cars that would sense a "test" environment and temporarily reduce pollution. I very much doubt that Intel deliberately engineered a permanent security flaw in order to enhance performance.


ps - Dear Mr. Intel, can I have my free (strong, stable, safe & secure) replacement CPU please?

 

[bulldog147]

Is my Intel i7 2700K Sandybridge affect by this?

 

[Nasher]

Yea window 10 is full of holes just by itself. You only have to run this to see how much you need to disable to stop MS knowing what porn you look at and when: https://www.oo-software.com/en/shutup10

 

[jabbz]

I thought all OS were compromised, as it's the cpu at fault. windows is not to blame if AMD work fine with it?

 

[Randomface74]

My point is, if PCs were vulnerable, who's to say you don't already have some stealthy virus collecting all ur stuffs?
Only way to be sure is nuke it from orbit?

Emergency Windows Update has just gone up :$
