In what planet do you live? Planet stone age Windows I guess, here's a list of productivity apps in which the 3D humbles the regular 5800X and sometimes even the 5950X, including engineering tools, physics simulation, file, photo and video compression and editing, 3D rendering etc etc... in some of them the 5800X3D is 2x faster than the regular 5800X.
Here's an appetizer:
Widely used professional engineering apps for physics and fluids simulations, the regular 5800X takes 177 seconds to complete the task, the 3D just 81... so much for "every single existing workload".

Have a nice look at the link below to check many other apps (there's many more) where the 5800X cannot match the 3D version, these are widely used by professionals, there's more out there than Windows and Cinebench.
