Workstation graphics may be a niche for most readers, but the trend is also very good here. On the one hand, there are very few multi-core optimized applications in the measurements of real-time graphics output, especially since this is not possible or useful in many areas. In return, of course, they benefit from a very high IPC.

However, there are also applications that have to calculate in parallel and are grateful for every additional thread. AutoCAD is a nice example of the clock dependency of fewer threads when it comes to the pure 2D design representation. But even the 3D graphics output sticks to the CPU and rarely needs more than 4 threads fortunately.

Cinebench benefits from the core number and the clock to the same extent and is therefore also one of the very few benchmarks where the Core i9-9900K can very clearly set itself apart from the Core i7-8700K.

Solidworks and Creo as full versions both juxtapose a wide variety of workloads, although real-time graphics (as opposed to rendering and calculating) are very important in terms of computing power per core.

The older versions of Maya and Catia, despite the potent Nvidia Quadro P6000, both already stick in the GPU limit, where it ultimately makes no difference whether a CPU has been overclocked or not. From the Core i7-8700K upwards, the differences are really only very marginal.

Even if the Blender loop relies on OpenGL and the real-time graphics, at least in beginnings various computing power is required. However, hardly more than 4 cores are really utilized, so that the IPC is more likely to come into play here.

The same could be said for the GPU composite score of 3ds Max, because in the end, whoever brings the highest clock to the road the longest wins. Multithreading is not really in demand.

Intermediate conclusion

In summary, it is hard to say that upgrading from a fast quad-core to a slightly faster eight-core hardly adds value. Unless you need something for Image & Ego. Then, of course, always.
