Thread: Why are CPUs stuck at 3Ghz ?

I am curious why CPU manufacturers are stuck at 3 GHz?

I understand we are utilizing multi core technology, increased the bus width and better use caching to give us the added horse power but that is only useful if your OS and Application can utilize it.

we are basically stuck around the 3.0 GHz viscinity because the more GHz a cpu uses, the more heat it outputs and because air is used to coolmost of the worlds processors the heat will be too much to handle and even liquid cooling has its limits, so since they are no longer able to simply compete GHz for GHz, they must find new ways for cpus to get faster while maintaining an acceptable thermal envalope.
