hmm this is opposite of the "fine wine" treatment. I guess i have been taking AMD's efforts for granted.

That's hardly new. It's much worse with an Intel system using Intel optane. It also makes a couple of games, but not most of what I checked slower and more stutter prone. That's why I don't have microcode mitigations enabled on gaming systems. But I do enable meltdown mitigations. Keeping the microcode the one I want is a hassle.

Maybe I missed the mention and apologize if I did but, have there been any documented successful MDS side channel attacks yet? Is it happening? As stated, we have known about other similar vulnerabilities for quite some time.

It looks like the 9700k was the better choice against the 9900k at this point? I was starting to regret it and nearly switched back when I still could. Glad I didn't, I guess.

I have come across and read a fair bit about Spectre/Meltdown and now this new one. Often I wasn't even searching for on this topic but it's hugely covered.

On the other hand, I have not come across a single case of a regular home user (excluding businesses here) who have been successfully compromised by any of these
chip flaws.

It's clear Spectre would be difficult to abuse, and with meltdown there seem to be varying levels urgency. Now this new one. But as stated do you guys think a regular
PC user who keeps his software up to date (I know it's a hardware flaw), has up to date anti virus, uses Google, email gaming, office etc, has a Lan behind a good hardware
based firewall router could/would be at real risk, not theroretical risk.

Seconly, the same set up as above with Remote enabled. (I read but have no idea if it's correct that remote can be a vector) is real world as opposed to theoretical chance of us
or anyone getting caught out by this. If direct access to a machine is needed most people don't let strangers with USB sticks into their homes, I can only conclude that the risk
is low, for me zero.

But I'm not sure about that. My feeling is that someone with out of date software, or carelessly clicks on weird email or web links is at genuine risk, (of many various Malwares) and it's all documented.
You guys on here would never fall for that, but some people are rather silly.

So back to the original question. Is there proof that any of these hardware defect have actually led to users being compromised? I haven't read a single case. What do you reckon guys?

This is actually fairly easy to answer, #1) a targeted attack would almost never target a consumer an individual. Think big companies. #2) Some of these companies (like Facebook, Yahoo, and others) didn't know they had been compromised for YEARS. So we might not even know who was hit by these exploits for years. Also, many times we found out the company found out years after, and then waited months or YEARS after that to tell the general public only when it was outed by a 3rd party.

You want true privacy? Go live in the woods with no electronics like in the early 19th century. Otherwise stop complaining.

@DarkPriest667

Thank you very much for your post. I now understand about this at least the basics.
Before your answer, I was embarrassingly wrong. I thought that impact on a user from someone using these chip exploits would be somewhat similar to various Malware. Oh my bad!

Now I get it, thanks again.

Win 10 ver.1903 fully updated
Latest drivers
Latest bios
and I get this :

I think you need CPU microcode update as well. It will be with your BIOS Update. Only solution is to change to AMD platform.

So the options I have are :

a) hope that Gigabyte release a new bios for my GA-Z270-Gaming K3 mobo

b) move to AMD

c) wait for the 2021 intel cpu's

but do we have any clues of how dangerous this flaw can be for the average home user ?

There's an post here explaining this flaw. The data they get from you is completely random. So basically, unless you are doing the same thing continuously then its kind of hard to get any useful information. It really depends on what you do with your computer. If your just mainly playing games or nothing of extreme importance, then it should be less concerning since your data is literally random. Put it this way, I would rather go email spoofing on average user than attempt this. It's more efficient and you get the useful information like bank account login, credit card number than using this intel hack.

Intel won't have this fixed without performance hits till 10nm/7nm stuff comes out. Unfortunately the only solution right now is AMD. AMD architecture is newer but somebody will find an hole to exploit in the future.
