Also, I find it a bit preposterous to consider that electromigration is the dominant factor in graphics card failure over time. I think its more likely one of the those capacitors leak or the MOSFETs blows.

Electromigration is mostly a factor of the fabrication process. There are professional devices that are built on the same exact process (and sometimes even using the same chips) that are required to operate for a decade.

I think it is a bit preposterous that you believe anyone said it was the dominant factor.  Hint: nobody did.

It would never come to my mind that an intel CPU would not perform it's job for centuries, how is this so different ?

No semiconductor will last centuries.  It is unlikely they even would last a decade of continual use.  As chips get smaller their lifespan will decrease.

And yet you link to an Electromigration wikipedia page in answer to Transisto's question that a graphics card would not perform its job for centuries?

"centuries" =/= "the dominant factor in graphics card failure"

Obvious troll is obvious.

Obvious troll is obvious.

Why list one one of the meaningless, complex, and rare failure modes when there's a much easier and obvious one for a novice to failure analysis to grasp?

I think you're the one trolling here.

He asked a question I gave him an answer. 
Transisto didn't ask what is the most likely cause of failure.  He asked why won't a microprocessor last a century.

Not every post in the thread has to directly relate to the OP.  Case in point your idiotic past 3 posts.  Feel free to have the last word.

And you chose one of the more difficult explanations as a goal to make sure he could not understand what you were saying?

Actually, you didnt even explain it, you just linked to it. Way to contribute to a discussion, idiot.

I do this all the time ... that's why I am a scammer Tongue

This behaviour is driving the GPU prices up for everyone Angry

Also, don't forget to OC the card to 1100 MHz clock then when it dies blame it was DOA or it broke by itself for extra scam points !
You're an idiot.  Overclocking doesn't break cards.

That's why overclocking does not void your warranty. Idioto !

No one has studied the effects of electromigration on 40 nm chips for a decade because they haven't been around for a decade! But if you run them on stock clocks at undervolted settings, my money is on that they will last a decade.

I've had a 1055T overvolted to 1.5v and loaded for pretty much all of its couple year lifetime, and no problems yet...  Keep it cool and it's hard to fry.  The problem is probably insufficient cooling and cheap PCBs/MOSFETs/chokes.
