A bit off-topic, but I remember some studies about 'under-powered' ASICs, ie. running with 'lower-than-required' voltage and just letting the chip fail sometimes. I guess the outcome was that you can run with 0.1x power and get 0.9x of correctness. Usually chips are designed so that they never fail and that requires using substantially more energy than is needed in the average case. If the application is probabilistic or noisy in general, additional 'computation noise' could be allowed for better energy efficiency.

That sounds awful for verification, debugging, reproducibility and safety-critical systems. Imagine this in a self-driving car. Scary.

Well, you could simply not use these in a self-driving vehicle.
