FAQ #1: ASIC quality:
Look at it this way, let's say there's an imperfect car manufacturing company, and not all the cars that come out of it have perfectly aligned and balanced wheels, and so to "increase yields", the car maker puts its cars (at the factory), through corrective studs that will align/balance out wheels.
Not all GPUs are born equal, not even in the same wafer. Some have higher electrical leakage, some have low. So to correct them in the fab, their degree of leakage are measured and corrective fuses are added to the GPU package, and correct VID set for the chip's leakage characteristics. Later, NVIDIA/AMD segregate "good" chips from "normal" based on leakage/VID, the "good" ones are put into higher bins, the "normal" ones go to reference / low-factory-OC cards, the "good" ones go to high-factory-OC cards. Multiple SKUs based on the same physical GPU are also carved out this way. "normal" ones go to lower SKUs, "good" ones go to higher SKUs.
