This is fascinating because it&#x27;s such a relatable physical demonstration of real physical CPU concepts such as overclocking, die size, voltage, reliability, tunneling&#x2F;leakage, architecture, multiple cores, etc.<p>For any kid out there who&#x27;s thinking &quot;why can&#x27;t they just make CPUs faster&quot;, this is a great way of explaining why. It&#x27;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.
