This story is all over the web, in case no one has heard about it I'm posting it here.
Will it have an impact on Intel CPU performance ? I don't know for sure but it looks possible.
QuoteTwo critical vulnerabilities found in Intel chips can let an attacker steal data from the memory of running apps, such as data from password managers, browsers, emails, and photos and documents.

And for those like me that just want to watch a vid:

Um... Oops? :o
Since I don't have a server it shouldn't apply to me so I won't worry. I couldn't get around the password and used a pin instead. Getting fed up with having to make up a account name and password for an account I won't use then seeing this made up name showing up in windows.
Since you guys have servers I'll just wish you luck.

here is what i found so far about performance issues

this is pretty much the takeaway I'm getting from that article:

Preliminary conclusion
Given what I am currently seeing, desktop users and PC gamers should not be worried about significant performance drops. Most test results do show a negative effect on performance, but we're really talking in a realm of 2% differentials here. The file IO tests didn't worry me either, and we used the fastest consumer NVME SSD on the globe to be able to see a bigger effect when measured. We did see a bit of a drop off in 4K performance, mostly reads up-to 3%. That's the worst I have been able to find out of all tests. Other than that you are looking at 1% maybe 2% differentials that could even be tagged as your typical statistical anomalies.
I would like to see some more benchmark tests over the next few days but yes it's looking like a 2 to 3% performance reduction on most Intel PC's.
No biggie I guess, the bigger story is how vulnerable have our PC's been and why didn't Intel spot this earlier.
Oh well, at least AMD have gained another 2 to 3% performance on Intel :P
Competition is a good thing :)
Thank God it won't affect games much then :P :LOL:

Yeah, that would have been unacceptable :D
Found this, it appears to be more than just Intel.

Some real world benchmarking after the patch:

This story is still going on, now with BIOS updates and it seems we are starting to see some more serious performance drop-offs with storage devices, SSD's M.2's, up to 40% in some cases. CPU and GPU performance seems almost untouched.
Servers are also seeing some problems now.
Watch this vid for more info, the SSD benchmarks start at about 9 mins but there is some info on the BIOS up-dates at the beginning of the vid.

This has turned into a right fiasco, hasn't it? :eeeek:

:sign-oops: Looks like M$ forget to check some older hardware compatibility.
Yes, that's surprising, I mean MS never does that normally...oh wait... ;D
What I don't get, and what simply makes no sense was that this update that seems to be bricking many AMD systems came with no restore point. Was this just a simple oversight? Or is it part of some plan between M$ and Intel to get users to fork over cash to get new systems? My inner conspiracy theorist is laughing his bum of, at present. :D
I have a team of people working in trailers all outfitted with military standard foil hats as we speak Dave.

Yeah that was naughty :no-no:
I see that M$ have withdrawn the patch for AMD powered computers today.

Joe smo: "wow glad i did not go with amd, i would not want a 5k brick sitting under me desk" :P
perhaps that is also m$ reason, try to make there customers feel good after they inserted a foot up there arse :LOL:
:o shocked i am :o
Syber, you do know we are talking about old AMD Athlon chips, the kind of thing you can buy for 20$ these days, it doesn't effect any modern AMD CPU's.
Quoteit doesn't effect any modern AMD CPU's.
Dough!!!!!!
I though you was referring to it was with ~all~ amd chips :P
