Phoronix: AMD Rembrandt: Windows 11 vs. Ubuntu Linux Performance

Yesterday I delivered my initial arsenal of AMD Ryzen 7 PRO 6850U Linux benchmarks against various other AMD Ryzen and Intel Core notebooks. That ongoing Ryzen 7 PRO 6850U is happening from a Lenovo ThinkPad X13 Gen 3 AMD notebook and this new "Rembrandt" device continues looking good under Linux. But prior to installing Linux, I did run some benchmarks of Lenovo's Windows 11 Pro on there for seeing how the Linux vs. Windows performance is looking for this Zen 3+ SoC.

Isn't zen3+ the one that introduce Microsoft coprocessor...that only works in Microsoft products?

Why not test a fresh Win11 22H2 with (supposedly) performance improvements (vs a year-old 21H2)?

The TSCP chess benchmark was showing better multi-threaded performance on Linux.

Quite interesting since according to the internet TSCP was written in the 1990s and is single-threaded. It supposedly only uses integer-based computations and doesn't use floating-point numbers at all. To me these "benchmark" results are just numbers and white noise, not meaningful data in any way.

Lenovo. Is working hand in hand with Microsoft. To produce products designed for and optimized to run Micosoft Windows.

placing a non industrial Ubuntu on said laptop. Will skew results towards Microsoft.
And you didn't thing we would notice.

The test is incomplete. Please add Windows binaries on Linux via Wine, so that we know which part of the difference is due to Windows and which is due to a different compiler.

That one you have to be careful. Some things run faster in wine because wine is not doing particular things correctly.

Finally a Windows version that has less market share than Linux on the desktop

Please note that at least some of the difference between Linux 5.15 & 5.19 stems from the fact that the former defaults to amd-pstate while the latter falls back to acpi-cpufreq, even though it's the newer kernel.

Also, both are using schedutil, which once again successfully disguises Linux's true performance potential, as usual...
