Storage degradation happens frequently. Even RAM loses effectiveness over time. Capacitors also degrade, but why doesn’t a CPU fail? I’ve never seen a CPU completely die just because it’s old. Interestingly, mined GPUs do wear down and reduce performance, possibly due to issues with the board and other parts.
It covers a period that's usually very broad. There are no moving components, which means wear is minimal. Heat stress may eventually cause failure, and heavy overclocking can accelerate this, though the overall timeframe remains substantial.
In everyday operation, a chip can work for many years before it stops. This happens because semiconductors are made by adding tiny amounts of impurities to a crystal of silicon, and the components of CPUs are now extremely small—modern parts measure around 10 nanometers, which is just a few hundred atoms long.
I compare their wear levels closely; both degrade gradually, though heavily overclocked use can accelerate it. The silicon absorbs significant current, leading to electromigration effects. Under typical usage, they should remain functional for many years, and users often stop caring before noticeable physical wear occurs.
