Intel/Windows 30% performance reduction

[Vali 83]

Yes sure, will not impact people which read emails and do browsing they say.. Really? I am not in that group...

I don`t think it`s the home PC user that need`s to worry to much, But the servers and sites that store our info on purchases is the real worry, if you were locking to hack anything that were the problem is a worry.  

PS ARM powers a lot of smart phones.

It depends on if you are CPU bottlenecked ;)

 

Aren't we all? :)

But after they've patched their systems (and it'd be grossly irresponsible of them if they haven't already done so), they're protected and any performance hit they experience isn't likely to be noticeable by end users.

This vulnerability (like many others) relies on the fact that hackers can get unrestricted access to your system - all the more reason to use a firewall and antivirus/malware protection.

Actually, it’s already been reported and explained that the trade was done automatically as a prevention to insider trading as per intels own rules. Nothing to see here.

Not as bad as some think.

That of course assumes that your anti-virus is capable of stopping every single attack vector, guaranteed.

1 year old, time to trash it.

And replace it with what?  There are no new AMD or Intel CPUs that address the issue.

Don`t Panic yet.

15-30% pending process, AWS (what we use - Amazon servers) and any virtualization (just about all "cloud" servers) will be impacted, perhaps not as bad as 30%, but even 15% reduction in performance is a BIG deal.

This is definitely a big deal and is real, heck it even made Radio and TV news (which rarely reports on anything remotely technical).  Intel and Microsoft are trying to down play the performance implications but since Intel can't address this via microcode updates and has to be done software side, that means there will be some degree of performance hit whenever shift from hardware to software implementations.

I hope we are provided the KB number so we can avoid the update ... with the implications of assuming the risk of the exploit and using other tools to temporarily block any such exploit on an as needed basis (i.e. web site visits or software installation process only and not applied globally).

I ran the tool on my 2 week old 8500 system and it reported "already Patched"  Hmmm.   Regards.

On my 6900K, my 7700K, and my 5960X, and my 7900X (all Win10 Pro 1709 PC's with latest KBs) the "tool" is reporting "This system is not vulnerable" ... but I'm not entirely sure what the tool is testing ... looks to me like it just does checks to see if I have Virtualization turn on in the EFI/BIOS (which I don't).

That tool is looking at the Intel ME issue from last year and is completely irrelevant to the latest CPU issue. At this point it is really confusing the issue and it would be great if the link could be removed.

That tool is for a different issue, not this latest CPU problem.

Agreed, which is why I take a multi-layered approach. That said, even using something which doesn't block everything is better than using nothing and just trusting to luck.

I left the PC ON, after my  flight today (P3D was closed) and got some rest, after I came, I saw it re-booted.

I checked the EventViewer and... "A reboot is necessary before package KB4056891 can be changed to the Installed state."

http://news.softpedia.com/news/windows-10-cumulative-update-kb4056891-fixes-meltdown-spectre-on-version-1703-519219.shtml

So more or less mandatory (or by "force") done...

This is the update related to the issue reported, as I see. 

I have Win 10.

I'm reading report`s that NVidia are patching there next driver update for release, and AMD and INTEL are going to have to go back to the drawing board and re-engineer CPU`s as one of the exploits cannot be patched in software.
