I found the i9 in macbook pro so severally throttled most likely because of heat that it underperforms compared to a 10 year old high end i7. The i9 in that from factor is pointless IMO.
I have an Intel I9 workstation machine, I use it mainly for developement. Let me tell you something: it's the most horrible machine I've ever had in terms of performance (based on compiling a very large C code base).
