I have a Intel i5 2500 that I paid $209 for in April 2011. I'm looking at new i9 desktop chips and they're like 50% faster. 10 years? WTF? The laptop chips are barely faster.

It would be interesting to see when these benchmarks were taken. I have a feeling that most of the i5 Benchmarks are from prior to the Spectre and Meltdown mitigations.

I consistently recommend Hennessy and Patterson's Turing Award Talk[1] as a good overview of the past, present and future of chip performance.

We've reached a point where you really can't get that much more frequency out of chips, and there's only so much you can do to attempt to get more done per clock cycle. Especially now that its made clear that much of these attempts lead to the various speculative execution bugs like spectre that have been discovered over the past few years.

The days where clock speeds on processors was doubling every year or two are long gone, and its not because chip makers have gotten lazy.

Things have indeed slowed down but you're cherry picking numbers. +50% single-thread but +200% in multi-threaded!

Agreed but I dont think I do much that would keep more than 4 cores maxxed out.

What about this benchmark?
