This is fascinating because it's such a relatable physical demonstration of real physical CPU concepts such as overclocking, die size, voltage, reliability, tunneling/leakage, architecture, multiple cores, etc. For any kid out there who's thinking "why can't they just make CPUs faster", this is a great way of explaining why. It's hard, and as you push the limits, reliability goes down. So the challenge is in keeping reliability high enough to be acceptable, and performance increased.
