According to a report by Phoronix, Ryzen 7000 processors run faster on Linux 6.0 The strange thing is that the reason for this has not been determined yet.Ryzen 7000 speeds up when security measures are turned off in Linux
According to reports, Ryzen 7000 processors run faster in Linux 6.0 when some security measures are disabled. It is not yet known what caused this anomaly in AMD’s Zen 4 architecture, but it is strongly recommended to keep these security features active on Linux.
AMD’s next-generation Zen 5 architecture revealed
Linux Kernel version 6.0 has several security measures for Ryzen 7000 such as Speculative Store Bypass. Also included are SSBD measures for Specter V4 and SWAPGS measures for Specter V1. On the other hand, the filing measures called Indirect Branch Predictor Barriers for Specter V2 are also included in Linux 6.0.
There are cases where performance goes up as well as goes down.

With AMD’s Zen 4 architecture, SSB Specter V1 and Specter V2 measures on Linux can be disabled with the “mitigations=off” command. Testing this situation, Phoronix revealed surprising results. During the test process, which consisted of 190 applications running on Ryzen 9 7950X, it was observed that the processor was 3 percent faster when security measures were disabled. However, it should be noted that this performance increase does not mean much for the ordinary user.
It is stated that the performance gains obtained when security measures are turned off are seen mostly in web browser-based applications. The most notable among these is Selenium, which achieved a high increase of 42.6 percent. On the other hand, there are applications that are negatively affected by the situation where security measures are closed. Among them, Stress-NG is at the top, which sees a 26.6 percent drop in CPU performance. However, when looking at the overall total, it is noted that performance increases have been achieved in most applications tested.
