Do you know what electromigration is?
Intel does, AMD does, they have been designing complex electronically dense circuits for decades. Do you genuinely believe that they will not adapt the paper designs that they fabricate/present for fabrication to minimise the effects of electromigration?
There is always a minimal amount of damage and yes pushing for the last possible bit of clock speed will exacerbate the problem BUT ITS A KNOWN PROBLEM, run within specs and the device will last years, run slightly out of spec and it should last a little bit less… run excessively out of spec… BOOM.
The problems being discussed in the thread should not be happening. ICs do last for many years, look at your lcd tv, your washing machine, your car, your Casio watch and if run in spec they should and will continue to do so.
For intel, something has gone wrong, whether it is a design bug, a power implementation bug .. whatever.. Intel has a problem that needs addressing.
Arguably chips like the “ks” chips encourage people to push the operational envelope for those devices… push it just a little harder… little more V, make a little more available power to draw… rinse and repeat… and it’s fun getting the extra speed. A new chip shouldn’t be approaching the margins out of the box, they never used to. It was a user’s choice to push the chip into its danger zone.
