I get that going 3900X will give me the fastest compile times, which is cool. But I hit the build button relatively infrequently, and anyway I'm usually switching to reddit if the build is going to take longer than a few seconds, so I'm actually more interested in minimizing the latency of all the moment-to-moment operations like Intellisense, refactorings, highlighting, code folding, etc.
I suspect that some of those operations are mostly single-threaded, but even if there is some degree of parallelism going on, surely this type of "bursty" workload is where Intel can still register an advantage?
So, in other words, do these operations more closely resemble Benchmark A: "Blender render time" or Benchmark B: "Max FPS in Tomb Raider" (and why don't we talk more about the difficulty of making these sorts of determinations)?
