Is the 2021 MacBook Pro worth it?

"Most Software developers also can skip the 2021 lineup since compilation and build of most languages happens in a single core and thats what consumes all the time."

First of all: "that's".

Secondly, anyone using modern tools has build pipelines that are capable of maxing out all available cores, including most developers targeting Apple platforms using their Xcode app. In those situations one also needs lots of RAM and fast I/O.

I found clang multi-core benchmarks on geekbench.com:

M1 Mac Mini 8145 = 63.5 Klines/sec https://browser.geekbench.com/v5/cpu/10517829

M1 Max MBP 13442 = 104.7 Klines/sec https://browser.geekbench.com/v5/cpu/10496766 (similar for M1 Pro, which should be the ideal model for most developers as they rarely need top GPU performance)
