So would two processors running at 2.5GHZ (just a random frequency I’ve chosen) but one from 10 years ago and one from this year be equivalent in processor power. Does this measurement mean they are the same in raw power?
###### 2.5GHZ (Old Processor) = 2.5GHZ (New Processor)?
Or is it because of new architecture that the newer one is faster and in that case newer is always better due to more cores etc.
In that case doesn’t it make it confusing to use gigahertz to measure the speed of newer processor in comparison to previous generations?
Sorry for the long question, it’s just always bothered me and confused me on how to choose the best processor.

Yup, sure is. People still do it though.
The frequency only tells you how many clock cycles occur in a second. As long as the same amount of work gets done in one clock cycle, then a higher frequency will give you a faster processor.
But the amount of work per clock cycle is not fixed. A modern processor will typically be able to do more work per cycle than a processor from 10 years ago.
