Re: Hope this dont slow down my i7 :(

Are you sure, @rongtw? A quick read of the DM article say X86, so maybe X64 systems aren't affected?

x86_64 only I believe.

That's where the performance regression is likely to come from

@jab1  Almost every Intel processor manufactured over the last decade contains a major security flaw that could be exploited in severe attacks. If that isn’t bad enough, patching the issue might slow down the performance of a CPU by up to 35 percent.

Re: Hope this dont slow down my i7 :(

OK @rongtw - I stand corrected.Embarrassed

I'll still be interested to see what, if anything happens to performance, some of the articles seem to give themselves plenty of  'wriggle-room' 5-30% is a wide spectrum.

Edit to add: I know there's no detail about this threat, but I wonder how close to your machine an attacker  will have to get, or how they would?

You can get the tool to check if you are indeed vulnerable or not https://downloadcenter.intel.com/download/27150?v=t

Status: This system is vulnerable.
Tool Stopped

Knuppel

 

So i wonder if the MS update also means i may have to update my bios too ? 

And if this update does slow our cpu`s down then what are our rights ? I mean i didnt pay for no slow cpu !!

That's for a different Intel flaw (though I suppose if you're affected by one it's likely you'll be affected by t'other)

I always buy AMD.

They are cheaper, faster and apparently more secure! Cheesy

Re: Hope this dont slow down my i7 :(

Could be all chips Now including AMD , ARM Undecided

The issue was originally linked to a flaw only in Intel's chips, but the firm said this was "incorrect".

As I understand it the patch will affect all chips irrespective of whether they are Intel, AMD or whatever.
