各位有谁知道为什么GPU的频率比CPU低得多

GPU比CPU复杂? 如果把CPU比作一颗高级炸弹，那GPU顶多算把10000个手榴弹捆一块。

Right.

Others, parallel calculation normally need longer time period. Frequency of one chip is decided by proper time sequence, i.e.  by the architecture designed by engineer. If regardless of right circuit functions, the frequency mostly decided by fabrication process.

不能这么比较，CPU中的晶体管大多数都是L1和L2Cache，真正的逻辑运算单元只占很少一部分，尤其像安腾这种专们为服务器而做的CPU，cache所占用的晶体管数更是达到了变态的程度，17亿晶体管中，真正的运算单元不超 ...

理由很简单，频率是不得已才往上台的

既然 CPU 不好并行处理，那就只能提高单个线程的速度了

未来的多核心化 CPU 也不是以提升频率为主了

Some right. One CPU core more complicate than one unit of GPU. However,the number of the latter much more than the former and it needs a slower-speed communication.
