If you’re personal system is powered by an AMD Ryzen CPU, there’s some good news. Microsoft has backported the rollout of AMDs Branch Prediction Optimisations to all Zen 3 and Zen 4 with the Windows 11 23H2 update and, in effect, giving the older Zen architecture processors a boost in their performance.
If you’re Ryzen-powered system hasn’t already updated automatically, you can just manually do it yourself. Just enter the Windows Update section and check for updates. In this case, the 23H2 update be labelled KB5041587.
For the uninitiated, Branch Prediction Optimisation is a feature first introduced with the launch of the Ryzen 9000 Series. To put into more layman’s terms, the new algorithm basically allows the chipset to run two branch predictions in advance, instead of just one. By allowing this, the CPU is basically able to make more accurate predictions in the branches, at a lower latency, and therefore executing instructions more efficiently.
The Brach Prediction Optimisations should prove beneficial to systems running Zen 3 Ryzen CPUs but as mentioned, the backport is technically in part to improve the red chipmaker’s latest and top-tier Ryzen 9000 Series CPUs, such as the Ryzen 9 9950X. Since its launch, the processor has received several less than favourable reviews – we haven’t received it yet, so we can’t say for certain – all because it couldn’t perform as well as the company claimed. “We expect the performance uplift to be very similar between 24H2 and 23H2 with KB5041587 installed,” an AMD spokesperson said.
