Hardware: Dell Inspiron 15 Gaming 7577, model number 7577-92774 (new machine).
I have an Intel Kaby Lake CPU: Intel© Core™ i7-7700HQ CPU @ 2.80GHz (Ark Intel).
I am curious as to what advantages / disadvantages an installed
intel-microcode package has, if I regularly update my UEFI/BIOS; the latest update was on 13 Jun 2018.
I also regularly check for vulnerabilities with the help of
spectre-meltdown-checker from GitHub.
Its output is the same as with or without
intel-microcode installed (I rebooted after de-/installation before each check):
So, I suppose from the security standpoint I am covered, at the time of writing at least.
What I am unsure of, are other aspects, like performance or stability with or without the package.
