Would a 2.5GHZ processor from a decade ago be the same speed as a processor now, at the same frequency?

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.

Just want to add that GHz is simply the instruction per second measure. There are other very important notion as caching layers which avoid having to go look into ram for data which takes time.
