but the million dollar question is how meany transistors will have to go bad before the cpu is classed as dead?
Lol quite the opposite, cpu's are much more broken than you think. It doesn't take many transistors really, some logic is not repairable, a defect in those usually means a scrapped or binned chip (it may behave at a lower frequency/temp combination). As for million dollar... I'd argue it's multi billion dollar question lol, test time makes up for 1/3rd of the cost of a chip. You try to test as much of the chip in as little time as possible, but test escapes are unavoidable.
