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.

An Important Note On The Alder Lake Mobile Power/Performance With Linux 5.19
After dealing with the Intel Alder Lake P GuC firmware breakage around Linux 5.19 Git that is now to be addressed by the upstream Intel developers, it was on to performance testing the shiny new Core i7 1280P with this kernel due to be released as stable within the next two weeks... For those concerned about maximum performance, there was a glaring performance regression for this Alder Lake P on the new kernel being released as stable later this month. Well, a default change in performance/behavior at least but the power efficiency / performance-per-Watt tended to be better on this new kernel.

Linux firmware guidelines are also being proposed to ensure kernel developers in the future don't try to break firmware support guarantees...
