Huge Intel CPU Bug Allegedly Causes Kernel Memory Vulnerability With Up To 30% Performance Hit In Windows ...Read more at https://hothardware.com/news/intel-cpu-bug-kernel-memory-isolation-linux-windows-macos#lexZvVoxHiJekKSh.99

I've read about this at other places too.

If this becomes true our hobby is in serious trouble. ..

 

Edit: Maybe better placed in hangar chat or hardware section.

Do you have to do the update when they roll it out. I have all updates shut off in w10 via the group policy editor. I will check my 4790k to see if it's at risk.

My system is vulnerable. 1 year old, time to trash it.

Kind regards, Michael

Don't see the need for doom and gloom as it's clearly patchable.

At the expensive of 5 to 30% reduction in performance. I believe a recall/exchange is in store!

Sorry guys, can someone explain what is this? I have an 7700K too. I will lose 30% when? What's Intel response to that? I can't imagine they won't fix this.

I have i7-5820K - NOT Vulnerable. 

 

It could be that chipset LGA 2011 and probably 2011 chipset successor are not vulnerable

 

- Just hype for no reason.  I bet this problem can be fixed by a cpu microcode.
