## AI 摘要

旧芯片被更换并非只因折旧。在更精细的制程下，更先进的芯片会因导线移动和熔化而更快失效。但更大的驱动因素是电力：企业用效率高出2-3倍的硅片更换机架以实现增长。

## 正文

Older chips are not replaced only because they depreciate. At finer geometries the more advanced chips fail faster from wire movement and melting. But the bigger driver is power： firms replace racks with 2-3x more efficient silicon to grow.
