I thought they had corrosion issues, how do you patch that?
You can't fix damage that has already happened, but you can stop more damage by limiting voltage as I understand it.
but how can the chips reach the advertised performance while being undervolted? especially damaged chips.
It's like spectre and meltdown you also lost the advertised performance. Less performance is better than a gaping security hole or a broken chip.
They can't.
I would expect this patch to come with a negative performance impact.
🩹
As I understand it the corrosion is provoked by the chip's operation, the patch reduces the voltage load which makes the corrosion less likely to happen or to advance less quickly.
Warranty replacement.
And here I thought, it would be good to go for Intel. Recently got a new PC with 14600KF. However, I have not had any issues with performance besides Deathloop (Launches, black screen and then dissapears).
EDIT: So I guess, I'm forced to wait until my motherboard developer/ company (MSI) announces that their users can update their BIOS manually? I'm curious whether, I'm actually affected by this or not. Though I guess, never gonna go Intel again. Next new PC will be having AMD (unless AMD makes such a mess as well, then it does not matter).
e.g. https://www.yahoo.com/tech/ryzen-3000-fix-sinkclose-vulnerability-183025768.html AMD has these sorts of flaws too, I don't know enough to tell if AMD is significantly better at this when deciding to buy
That AMD security vulnerability doesn't physically damage the CPU while this Intel flaw does. Thats a drastic difference so the two are not the same
So far the AMD security flaws aren't causing physical CPU damage, so Intel definitely wins the screw up award.
That exploit required kernel access to begin with, which at that point, you have much bigger problems.
Unfortunately, this problem is larger than a micro-code update. The main issue the user is likely referring to is Intel shipping defective product (oxidation issues), denying warranty claims for said defective product, then staying quiet when it's proven they have been shipping defective product. Intel could have owned up to the issue and proactively recalled defective units, but, they didn't do the honorable thing, not even close.
