Leaked Windows 11 build boost Intel hybrid “Lakefield” CPU performance

Is Windows 11 task scheduler ready for Alder Lake?

This week was all about leaked Windows 11 ISO. This build was clearly far from the final version, but it gave us a lot of information on the upcoming operating system from Microsoft. 

The leaked Windows 11 has a lot more in common with Windows 10 than expected. The developer preview ISO that leaked is clearly a few months old, which is best illustrated by numerous references to Windows 10 in the system files. Not to mention missing widgets, apps, or functionality that was expected to arrive with the new system. Windows 11 also supports WDDM 3.0, which was first introduced Win10 Insider Preview “Cobalt”.

While WDDM upgrade and Microsoft Store updates were to be expected with the newer Windows, enthusiasts have been eagerly awaiting news whether the new installment in the Microsoft Windows family will also introduce changes and improvements for heterogenous CPU architectures, such as the upcoming 12th Gen Core Alder Lake series from Intel.

As it turns out, the leaked operating system already provides a small improvement to so far the only hybrid-based Intel CPU series: Lakefield. These are low-power CPU series featuring only 1 big core and 4 ‘small’ cores. Intel is to increase the number of these CPU cores with Alder Lake significantly, which raised the question of whether it will favor such designs in the future.

Based on HotHardware testing, Lakefield Core i7-L16G7 CPU indeed does appear to have higher performance in early Windows 11 build. The site claims a 5.8% boost in multi-threaded Geekbench 5 score and a 2% higher single-thread.

A modern synthetic benchmark such as Cinbench R23 sees a big improvement in single-core threaded tests, with nearly 8.2% performance uplift:

PC Mark 10 is probably closer to real-world testing as it tests various workloads simultaneously. While Windows 10 was clearly better in the Digital Content Creation test, mostly due to the fact that Win11 does not have a dedicated driver yet, the Win11 has shown performance improvement in all other tests:

With those performance improvements in mind, one would expect to see similar gains with Alder Lake, which is now set to launch later this year. Alder Lake will also feature Intel’s Hybrid Technology based on high-performance and high-efficiency cores. Its successor codenamed Raptor Lake as well as rumored AMD Strix Point APU is also believed to feature such design.
