Intel Alder Lake CPUs are a lot more efficient on Windows 11 than on Linux

Lately, it has become a bit difficult for computer enthusiasts to choose between Windows and Linux operating systems. A new study shows that Intel’s Core i7-8700K CPU is more efficient on the Microsoft OS than on most Linux distributions.

The “intel alder lake” is an Intel CPU that was released in 2017. The Alder Lake processors are more efficient on Windows 11 than on Linux.

According to recent tech performance assessments, Intel’s Alder Lake CPUs outperform Linux-based operating systems while running Windows 11.

This discrepancy stems from problems with Linux’s cluster scheduler, which isn’t designed for Alder Lake’s hybrid architecture.

What this implies is that Alder Lake, the new Best CPU for Gaming, is better suited to Windows 11 than Linux, which is unexpected because Linux normally surpasses all varieties of Windows. 

In every circumstance, Windows 11 outperforms Linux.

A Core i9-12900K with Windows 11 Pro, Ubuntu 21.10 + Linux 5.16 git, Ubuntu 21.10, Ubuntu 21.1.0 plus Linux 5.15, Clear Linux 35250, and Fedora Workstation 35 were used in the tests.

The operating systems were also put through their paces using a variety of benchmarks, such as browser benchmarks, video encoding, picture encoding, blender, and more.

To be more exact, Windows 11 Pro outperformed the other six operating systems in 45 percent of the tests, making it the best operating system for Alder Lake systems. 

Because of issues with the Linux scheduler and its interaction with Alder Lake CPUs, Microsoft’s newest operating system won.

Just in case you weren’t aware, the Alder Lake chips include two distinct sorts of cores.

The massive, rapid Performance cores (P-cores) are combined with a sprinkling of tiny, strong Efficiency cores (E-cores), which munch through background tasks at breakneck speed. 

The Linux scheduler was built to manage many core clusters, but not to distinguish between various kinds of cores, such as Alder Lake’s P-cores and E-cores.

Unfortunately, as with Windows 10, this implies that the scheduler is oblivious of the performance variations across the cores.

As a consequence, workloads that should be routed to the faster P-cores will be delivered to the E-cores, and vice versa.

To get the optimum performance, Linux and Windows 10 will need to provide a way to connect with Intel’s Thread Director, which supplies the operating system with real-time information so it can better schedule threads to the proper sorts of cores.

For Linux, there is currently no fix (other than completely removing the E cores). There’s a chance that Linux 5.16 will provide greater Alder Lake compatibility, but there’s no way of knowing when or if it will happen.
