假如电子设备所有的能量都能转化为算力,那得有多快?

    去掉屏幕等一些消耗,光看 CPU,给它多少电也就是能量,它就能全部转化为算力,这种转化该怎么计算呢?

    纯理论计算的话,可以了解一下 Landauer's principle
    https://en.wikipedia.org/wiki/Landauer%27s_principle

    After setting T equal to room temperature 20 °C (293.15 K), we can get the Landauer limit of 0.0175 eV (2.805 zJ) per bit erased.

    以我浅薄的知识认为,量和率是两个概念,就好比你问,如果所有油都给一台发动机,他能有多快一样。一秒用完就快,一亿年用完,就慢。
