AMD puts a lot of pressure on Intel in the desktop segment. In order to avoid abandoning the market to the competitor completely, the Intel Core i9-9900K has now been updated as the 9900KS. Intel advertises a stable 5 GHz on all cores in Turbo under load. We evaluate in detail whether this is also true in practical operation, since AMD had some problems with its Ryzen 3000 series to achieve the specified clock speeds in some cases.

Ah, for a second I confused this with the 9990XE.
I think it would have been more appropriate to compare the i9-9900KS with the Ryzen 7 3800X and not the 3700X since we are talking about Intel's best 8-core CPU.
