Not too long ago, we carried out our efficiency expertise evaluate of Home windows 11 24H2 towards model 23H2. We initially examined an in-place improve after which adopted it up with a clear set up testing to notice the variations. There have been some somewhat stunning outcomes however the majority of check information confirmed minor variances.

Nevertheless, not everybody could also be so fortunate and among the current Home windows patches (KB5050094 / KB5051987) could also be inflicting varied points like recreation crashes as Neowin discussion board member kiddingguy discovered it a couple of days in the past.

However a couple of recreation crashes will be the least of the concerns as a report from media outlet Borncity discusses how considered one of its readers got here throughout a performance-crippling bug that may go unnoticed if the person is just not paying consideration.

The person famous the issue on an Intel Extremely 9 285K CPU ASRock system whereby Home windows 11 will go right into a type of power-saving mode when the duty like an utility is minimized because the CPU enters a state of low utilization and aggressive downclocking. The person confirmed this on each Prime95, which is an artificial stress check, in addition to 7-Zip benchmark, which is a real-world utility for archiving recordsdata.

It’s noteworthy right here that Microsoft does formally assist the Intel Extremely 9 285K on Home windows 11 24H2 as per the most recent replace to its CPU assist record.

The screenshot beneath reveals the CPU utilization and clock speeds on Activity Supervisor when the app is minimized or not the main focus. As you may discover, the above picture clearly reveals a lot larger clocks and utilization with no throttling.

The affected person additionally added that the identical downside was not prevalent on a earlier gen Intel i9-12900K and AMD’s Ryzen 9 9950X, regardless that the latter remains to be not on Microsoft’s 24H2 assist record.

That will additionally clarify why we didn’t come throughout such a bug throughout our testing since 14700K shares the same architectural design because the 12900K as 14th Gen nonetheless has hyperthreading (SMT).

Apparently, this isn’t even the primary time that such studies of Home windows 11 hamstringing the efficiency of gadgets have surfaced as again in September, it was discovered that Microsoft’s desktop OS may very well be extremely inconsistent on this division.

May this maybe additionally clarify the slowdown of CPU efficiency in 2025 that was not too long ago highlighted by PassMark? That may very well be some meals for thought.
