If you read the link it’s actually two cpu cores on a single cpu die each returning a string. Then 3 of those cpus send the resulting string to the microprocessors which then weigh those together to choose what to do. So it’s 6 times redundant in actuality.

That’s not 6x though.
It’s a more solid 3x or 3x+3y, which… if you had a power failure at a chip doesn’t take a 6x to make it 5x. It makes it 4x with the two remaining PHY units because two logical cores went down with one error.
The x being physical units, and the y being CPUs in lockstep so that the software is confirmed to not bug out somewhere.
It’s 6x for the calculated code portion only, but 3x for CPU and 1-3x for power or solder or circuit board.
I know it’s pretty pedantic, but I would call it the lowest form for any quality, which is likely 2-3x.
