> A very frequent real-world workload is the compilation of a software project, which scales almost perfectly with the number of cores.

Geekbench has that as a subtest.

> For the other multi-threaded tasks, like running certain CAD/EDA applications, I use well-optimized programs, either by others or by myself.

Those seem pretty clearly out of scope. You want a workstation benchmark, not a consumer benchmark.

> This would be fine, if it would be more clearly specified when the Geekbench benchmark is distributed.

The descriptions of what Geekbench is are adequate. You're asking for Geekbench to exhaustively list what it isn't to stop you from imagining it to be a one-size-fits-all benchmark, which couldn't possibly exist.

> But others appear to not be aware of this and I have seen frequently erroneous claims on the Internet that some laptop or even some smartphone would match or exceed the performance of a desktop or of a bigger laptop, even one with a CPU with more cores, based on the published Geekbench multi-threaded results, while in reality that desktop or big laptop has a much greater throughput.

Again you seem to be unable to stop asserting that workstation or server use cases are the only ones that are real.
