Why doesn't skylake have a 6ghz CPU

[DMG5760]

I know CPU have gotten better since I was little but why were they clocked at 3-4 ghz then and so are our modern high end ones whys this and how is it measured

Because if they clocked it at 6GHZ then they would have to package some liquid nitrogen with the pre-packaging since the cpu would most likely go on fire.

Because Moor's law died a long time ago.

moores law just predicts a doubling of transistor count. That's all, and that's holding reasonably true.

The answer is because at high frequencies more power is consumed, and so what has been happening is a better usage of the power consumed, so a modern 3-4Ghz is easily twice as powerful as a Pentium IV 3-4Ghz. The Ghz are irrelevant, an amd at 3.5 performs differently to an intel at 3.5.

Because it's not all about clock speed
