Do Computer Chips Actually Get Slower With Age? The Real Science Behind Silicon Aging

Older CPUs and GPUs usually do not get inherently slower with age; most “slowdowns” come from dust, dried thermal paste, software bloat, or heavier modern workloads.

Real silicon aging does happen, but it mostly shrinks stability headroom rather than causing dramatic speed loss.

Mechanisms like NBTI, HCI, TDDB, and electromigration can make high clocks or low voltages less stable over time.

That means aging chips are more likely to fail at old overclocks or undervolts, even if normal everyday performance still feels similar.
