Interesting take away.

"It was a 12% improvement for the Core i9 9900K in affected workloads by booting with "mitigations=off" on Linux 5.3 under Ubuntu 19.10. In the case of the Ryzen 9 3900X was a 4.5% difference. Notable with this overview though is that without mitigations, the Core i9 9900K comes out just ever so slightly ahead of the Ryzen 9 3900X. rather than losing by about 6%."
