So after 7 generations of improving performance by 3-5% a generation nearly all of those gains have been wiped away by a single bug, and other than the newly supported architecture, instruction sets, core count and gains in raw clock speed, there is essentially no compute difference between a 6700k and a 13700k?
1) are all these vulnerabilities being exploited in the wild today?
2) since everyone is running mitigations, no one is spending much time to exploit them, so why shouldn't I turn them off myself?
Every time there's a new vulnerability out, I ask the same question and I still don't have a valid reason why I should keep them on. Herd immunity does not only apply to viruses.
In fact, the slower our CPUs get because of these fiascos, the more performance I might squeeze out of something no one is exploiting in the wild, unless I have proof of the contrary.
Of course, this works only if I disregard anyone's opinion and do it. If everybody turns off mitigations, then I'm unprotected.
Yes, in addition to the prior zenbleed/spectre series of attacks, inception is the catchy name for the latest round of AMD focused speculative execution exploits
