For my work machine I don't care much about the price (to a point) or the power consumption. I want the fastest compiles money can buy. This article is exactly what I want to see, and confirms my decision to go for the 5900x. Now if AMD can just get them in stock. The local waiting list is months long.
Depends on the language of course. Most JS tools are strongly single threaded. Rust is quite good for multi core and benefitted hugely from my 3900x but even that only keeps all the cores busy for the first 60% of a compile then we're limited by the slowest chain of dependencies.
The compiles are parallel, but not all work can be done in parallel or divided among 32 threads equally. So from 24 to 32 threads is not typically a 33% increase unless your compiles are huge (like the Linux kernel).
I'm opting for the 5950x. Yeah it's 33% more cores for 45% more money, but in for a penny.. The 5900x is already split across 2 core complexes and the 5950 will just add 2 more cores to each. Cinebench multi-core does shows exactly what you would hope adding the extra cores: 5900x is 75% the score with 75% the cores vs the 5950.
