AMD's Ryzen 5800X3D CPU performs better on Linux, not Windows 11

At the end of 2021, so not that long ago, we were telling you about how Intel Alder Lake CPUs are a lot more efficient on Windows 11 than on Linux.

The story was the same with the AMDs suite of processors, which after intensive testing, proved to work much better on Microsoft’s new operating system.

However, things are slowly starting to change, apparently, and Windows 11 might lose another battle to its main competitor, Linux.

Why? Well, over these last few months, Windows 11 has had a really hard time keeping up with Linux in terms of performance.

We’re going to look at test results from Phoronix, as we did last time, and see exactly what experts mean when they say this.

Windows 11 is losing the performance battle to Linux

As we mentioned, back in 2021 when Intel released its 12th Gen Alder Lake CPUs, based on the Performance Hybrid architecture consisting of Big E-cores and Bigger P-cores, the story was another.

The Redmond-based tech giant and Intel worked together to optimize the Windows 11 scheduler for the new kind of architecture.

That is why the Intel Core i9-12900K was found to perform significantly better on Windows 11 compared to Linux, as we’ve shown you.

The truth is that Kernel version 5.16 was also found to be not quite ready for the new design, as it was also handily beaten by Windows 11.

According to performance experts, tests that were conducted back in July found Linux no longer trailing the Windows operating system.

This batch of tests focused on the comparison between Ubuntu 22.04 LTS and Windows 11, and Ubuntu was actually ahead of Windows 11, believe it or not.

Indeed, while using a mobile Alder Lake Core i7-1280P CPU, Microsoft was still ahead, though the performance gap had shrunk significantly.

Things took a turn for the worst for Windows as patches reveal further optimizations are being made on Linux for hybrid x86 processors like Alder Lake and its succeeding Intel architectures.

Keep in mind that, for AMD as well, where hybrid CPU designs have not materialized yet, performance comparisons have found the gap between Windows 11 and Ubuntu to be slim.

This data we are presenting you is from only a few days ago when experts over at Phoronix did a follow-up testing session using an eight-core Ryzen 7 5800X3D.

When talking about this state-of-the-art processor for your PC, please take into consideration that this is AMD’s first processor launched with a 3D V-cache on board.

Thus, out of the 89 tests conducted in total, Ubuntu 22.04.1 has actually won 81 or 91% of the tests, a result that will drop a lot of jaws in the Windows community.

Microsoft’s Windows 11, on the other hand, only won 9% of this whole event, which is no more and no less than 8 tests. Talk about a crushing defeat…..

To draw a line, the biggest performance differences are seen by far in the Renaissance benchmark Instance Metadata Service (IMDS) test, followed by DaCapo Tradesoap.

Windows 11 wins the other DaCapo test which is Tradebeans, but only by a small margin, fac that will surely disappoint a lot of Windows fans.

If you didn’t catch it, Geometric Mean reveals Ubuntu was about 10% faster on average, which is pretty impressive considering that there were close to 90 tests in this comparison.
