With Linux 5.7 the kernel is preparing to use the Schedutil governor more often on Intel systems. That change affects the CPUfreq default as well as the Intel P-State driver when in passive mode. While Schedutil holds a lot of hope, at least on Linux 5.7 with the testing I've done thus far the results show the raw performance slipping while testing on more platforms is forthcoming.

Here are similar tests done in looking at the server mitigation impact with the near-final Ubuntu 20.04 LTS while testing server workloads on Intel Xeon and AMD EPYC server platforms. Like the desktop tests, the mitigation impact with the out-of-the-box protections against Spectre, Meltdown, and friends is being compared to booting the same Ubuntu 20.04 release with "mitigations=off" for run-time disabling of the relevant mitigations on each platform.
