This affect newer chips like 10900k?

Only important thing is performance loss. What @user1 wrote indicates that for certain instructions, loss is up to 97%.

I wanted to ask here exactly, what are those instructions doing? Because in this case would be better to patch compilers to use them as less as possible.

Intel is lucky that their server customer can't just jump to Epyc solution in the snap of a finger...

Well this is not good for Intel. I am glad that I am switching to AMD for my CPU. Well I guess it is safe to assume that CPUs below Broadwell are effected by this as well.
You are 100% wrong the end user would be the most likely effected group of this vulnerability if they don't know what they are doing.

Kinda funny when you think about it: Zen2's rdrand was dysfunctional to the point that AMD's fix was basically to disable it. Thanks to security issues, Intel's rdrand is crippled so badly that it might as well be disabled.
I think we can effectively declare this instruction as obsolete.
I don't know how many times it needs to be said:
The entire reason these vulnerabilities are scary is because you can't detect them. You're not supposed to know if they're exploited; that's the whole point.

And they all laughed at me when I said there were more

Oh my.....oh my........OH MY..!.?!.?! When will this vulnerability train ever stop "chuffing" along?!?
