The fact that multithreaded performance is worthless for you does not prove that this is true for most computer users. During the last 20 years, i.e. during the time interval when my computers have been multi-core, their multithreaded performance has been much more important for professional uses than the single-threaded performance. The performance with few active threads is mainly important for gamers and for the professional users who are forced by incompetent managers to use expensive proprietary applications that are licensed to be run only on a small number of cores (because the incompetent managers simultaneously avoid cheaper alternatives while not being willing to pay the license for using more CPU cores). A decent single-threaded performance is necessary, because otherwise opening Web pages bloated by JS can feel too slow. However, if the single-threaded performance varies by +/- 50% I do not care much. For most things where single-threaded performance matters, any reasonably recent CPU is able to do instantaneously what I am interested in. On the other hand, where the execution time is determined strictly by the multithreaded performance, i.e. at compiling software projects or at running various engineering EDA/CAD applications, every percent of extra multithreaded performance may shorten the time until the results are ready, saving from minutes to hours or even days.
