The PostgreSQL database server also sees a significant uplift when disabling the relevant mitigations on these processors, but the Ryzen 9 3900X was still ahead of Intel in these tests.
The GNU Octave performance on the Intel CPU came ahead of the AMD Zen 2 CPU when disabling mitigations.
Disabling mitigations also generally meant Intel was delivering better Redis performance.
The micro-benchmarks where the Core i9 9900K has the greatest hit from these software mitigations is certainly with the context switching performance.
