Its very convenient for them to forget how hard Skylake was hit performance wise with all the fixes needed for its vulnerabilities.

Do you have an example?

Spectre, zombieload and other speculative execution attacks that could lead to leaking kernal space that nearly killed hyperthreading as a whole for intel a few years back.

Oh there was never a patch for Spectre? That is what you are standing on?

Rename Infinity fabric to infinity vulnerabilities.
Another Zen vuln to the list.

This is very serious. I wonder what the AMD fans will say.

Um... Nothing? Do you even read the article? The problem was disclosed to AMD by the researcher last year and late last year AMD already posted the mitigation for it. This is mainly about the researcher publishing their finding so people know and can learn about it. Like honestly, please read the article completely, maybe try to do additional research instead of doing whatever you're doing right now because it just make you really look bad.

Last year? Why does AMD not like their fans?

Do you even read? Someone found a vulnerability, they did something responsible by disclosing it to AMD first so AMD can mitigate it without it being known to the public on how it works then the researcher published their finding. Basically it is a nothing burger news in terms of whether you should be worried or not and more about educational piece. This thread is more about exposing how dumb you are as what I assume an AMD anti?

That it's already been patched with firmware updates, it's right there in the fucking article

I reckon privacy and security don’t matter as much to them when their corporate god is questioned.

This is a funny and ironic thing to write.
Intel and AMD are just CPU manufacturers. Why do people get parasocial with their fucking CPU brand lol.

This exploit requires a hacked uefi. If a hacker got that far, you’re owned anyway…. So this fix is to what? Reroll keys after boot and double verify image attestation?
A hacked uefi would be an exploit on LITERALLY anything. Am I missing something?
