Question

CPU中电能全部转换成热能吗？

请详细分析
我问这个问题的主要目的是在选购CPU和显卡的时候比较各型号的发热量，如果电能全部转换成热能，那么只要考虑功率就可以了。

其实根据能量守恒就能得出结论，至少是99%转换成热能。有些人以为CPU进行数据计算要消耗能量，其实信息的传递和处理是不消耗能量的，信息与物质世界应当隔离来看，不能用物质世界的规律看待信息世界。

现有的回答都不能令我满意，要是再没有好的回答，我就要撤销问题了。

Answer 1

你认为就两种能量之间的转化吗 ??电能初了转化为热能就不能转化为别的吗,它跟电炉子的工作原理不同,电炉子是纯电阻电路,而CPU的热只是运算中转化为其他形式能的其中一种,工作原理当然是不同的.

Answer 2

主要消耗在高速开关的损耗上。
分布电容和分布电感是无功分量，不直接发热。
少部分能量，是向外围电路输出、驱动而传递出去。

Answer 3

不可能全部都是热能

Answer 4

CPU是用来干什么的？处理数据，处理数据不用做功只发热？明显不是，所以CPU转化能量用来运算，这样应该没错吧

Answer 5

在世界上任何的能量转化都没有可能是100%的/...最多是99.9999999999999999999999999999999999999999999999999999999999999999999```````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````
