If you simply buy multiple chips at once and train on them, you may overfit because they are all likely from the same wafer. If you spent an effort and bought chips from multiple sources, they might end up being all the same hardware revision. And even if you got all existing hardware revisions, there is no guarantees that the code will keep working on new hardware revisions which has not came out yet.
There is also problems with chips aging, related circuitry (filtering capacitors age too, and the power gets worse over time), operating temperature, faster degradation from unusual conditions...
As long as all you look at is inputs and outputs, it is impossible to not to overfit. For a robust system, you need to look at the official, published spec, because that's what the manufacturer guarantees and tests for - and AI cannot do this.

Why not? All you have to do is run it in a simulator.
