on a modern CPU with billions of transistors does every single one have to be functional for the CPU to work or is there some redundancy if one fails?

Question

Additionally if my CPU has one transistor fail and yours is perfect, will yours be faster than mine?

Answer 1

Note that CPUs often come in a range of models based upon a single die. If there is a single defective core, the manufacturer may have the option as selling that chip as a lower model with less functional cores (or a lower clock speed) as opposed to the full flagship part.
