At least for the workloads tested this round, when booting the new Intel Core i9 10900K "Comet Lake" processor with the software-controlled CPU security mitigations disabled, the overall performance was elevated by about 6% depending upon the workload. Here is a look at the out-of-the-box security mitigations for this new Intel desktop CPU against foregoing the default CPU security mitigations and running an unprotected configuration to see what the pre-Spectre performance looks like.
