Hardware

This is the crux of the issue. People talk about "ST workloads" vs "MT workloads", but the reality is that single-threaded workloads largely do not matter, it's all stuff that, at the very worst, is done after a few seconds. MT performance, on the other hand, can save you hours of productivity depending on what your work is.

We are long past the point where ST performance matters for the "snappiness" of systems. Zen 3, Alder Lake, M1 and newer are all more than perfectly "snappy" in any modern system. Gaming is the last use case where ST matters so long as you have a minimum amount of cores, but for professional use cases there's nothing to even discuss, MT is the only thing that matters.
