What happens if in a modern CPU chip one tiny transistor doesn't function properly or is broken?

Does the manufacturers bin it or is it still usable with a defined percentage or circuitry disfunction?

    Both of those can happen depending on the particular CPU but usually it is just binned. But sometimes, if there there are variants of the device with extra features/cores and the basic features still work, it can be sold as the basic device. In fact I gather that for some big chips, they only fabricate the high spec version and lower spec versions are always devices with failures in specific regions and they then disable that whole region.

    It depends on the CPU but usually it is a Tax write-off.
