For some reason, I'm reminded of the 486 math processor screwup of 1992 (?). As I vaguely recall, the math coprocessor might have errors in the fourth digit of significance. Intel offered to replace the affected chips.
I think it is the Pentium FDIV bug. IIRC only the server CPU was replaced in the whole office, don't remember why.
From TFA: microcode can't fix it, lol. AMD is not affected. Shouldn't Intel do recall again?
I think they might go bankrupt ;) And think of all the work for sysadmins swapping CPUs & swapping systems... I think we are going to be stuck with OS level fixes that are potentially very bad for performance. People are already grumbling about the potential impact on AWS & other cloud providers... Speculation about a 30% performance hit?! https://www.reddit.com/r/technology/comments/7npcgu/kernel_memory_leaking_in...
