Is there such a thing as a processor resource?

Question

Iron

I understand that there are no moving parts in processors, so the processor resource, in theory, cannot be exhausted. For example, is a processor able to stand idle at 100% load for several years and not fail at the same time? Naturally, subject to other conditions - normal cooling, etc.

Answer 1

Actually, the current generation of processors based on 22nm technologies is designed for 20-30 years of use, after which the processors experience a "phase shift". Server somewhere on 50-60. Overclocking and other bullying greatly limit the lifespan. After all, no one has canceled diffusion on such micro-scales, and wear will occur in any case at appropriate temperatures. Therefore, server hardware always operates at reduced frequencies and temperature conditions. Actually, this topic was recently raised by Linus Torvalds - given the expected level of errors and failures, the situation is rather sad ...

Answer 2

Sooner or later, any device will fail. Even without load, if you wait long enough. :)
The processor is 99.9% likely to be replaced due to obsolescence before it fails. With this in mind, its resource can be considered unlimited.

Answer 3

In theory, a few hundred years, in practice I think about 10.

Answer 4

For example, is a processor able to stand idle at 100% load for several years and not fail at the same time?

No problem. In 2010, I wrote off a system unit for 486, which worked every working day. Still alive, percent kept in the collection. Not to mention the fact that so far all sorts of P3s work for different organizations.
Linus is a great programmer, but he doesn't know much about hardware. In order to dispel doubts - server processors are made using the same technologies and microarchitecture as desktop ones. Unless testing of finished products is tougher. Well, technologies like ECC, which does not apply to processors as such.
Under the conditions of a real task, they can be considered eternal - if you level out such factors as "meaningless power surges", overheating from a fan stop, etc., then they will work for 20 years and become as relevant as the mentioned 486 in 2010.
And server processors operate at reduced frequencies , which is not why . Moreover, the range of frequencies and cores of server processors differs from desktop processors both up and down. For example, show me an Intel desktop processor with a frequency of 4.4 GHz :) and I have a server one.
