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.

Two 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:

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.

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

Quote from: 3DGuru
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  Tongue

Competition is a good thing Smiley

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.
