VBS improves the security of a system but also bogs down performance.
How much that slowdown is depends on the chip being used and other factors.
AMD explained why its benchmarks of Ryzen 9000 CPUs differ from figures seen by reviewers.
Using an Admin account enables specific branch prediction optimizations that better take advantage of Zen 5.
Those branch predictions are not utilized when logged into a standard account, though that will soon change.
The change is already in testing among Windows Insiders (starting withWindows 11 Build 26100).
AMD had to update its figures regarding Ryzen 9000 CPUs and gaming performance.
Improvements vary based on the game played but are generally around 2-3%.
AMD shared the following figures, which indicate game performance in terms of frame per second (FPS).
“We’re collaborating with Microsoft to roll out this optional update to all Windows 11 users soon.”
Parts of AMD’s benchmarking setup are likely to turn more heads.
For example, AMD used DDR5-6000 memory in its original testing to compare its chips to Intel.
But Intel chips can handle faster memory speeds, making the use of identical memory interesting.
AMD’s new testing used DDR5-7200 memory on the Intel systems.
AMD also used Intel’s default power profile during testing.
That opens another can of worms, sinceIntel’s 13th and 14th Gen CPUs have had instability issues.
Intel said customers shoulduse official power settingswhile a fix is worked on.
Those issues affected AMD’s initial findings, according to the company.
That figure has since been changed to 5-8%.
