Yes all chips [graphics and cpu] suffer from what is called the Silicon lottery.
This is why overclocking is not an exact science and why overclocking exists. [otherwise manufacturers would just overclock everything to the max and sell it that way]
Basically, due to the way in which chips are made, each chip requires a different amount of Voltage to run at a specific frequency [GHz/MHz]. So in general if you can overclock very high at reasonable voltages or otherwise and get stable performance, you've "won" the silicon lottery.
Alternatively, if you lack proper cooling it's also considered winning the lottery if you can undervolt a chip by a certain amount and have it be stable, though this is not as sought after, so there won't necessarily be as much information on that side :lol:
This.
But it's also worth noting 2 factors:
1. Chip quality on average is increasing due to production technology increasing. This means there will be more consistency between two of the same processors.
2. Processor binning is commonplace. This means that buying a high end version of a GPU will guarantee a certain level of stability, while low/mid level versions will often be untested or failed to meet stability levels.
To a degree, these things help to cancel each other out.
