Windows 10 vs. Ubuntu 20.04 Linux Performance On The AMD Ryzen 7 4700U

These results certainly weren't what we were expecting (or hoping for) when starting this Lenovo IdeaPad benchmarking.

Out of 55 benchmarks ran on the Lenovo IdeaPad 5 with Ryzen 7 4700U, Windows 10 came in first place 69% of the time.

Or if taking the geometric mean of all 55 results, Windows 10 was about 10% faster than Ubuntu 20.04 LTS with the Linux 5.7 kernel for this Ryzen 7 4700U laptop. This was unexpected given our past benchmarks where most modern Linux distributions can normally whoop Windows 10 quite well on higher-end hardware. Presumably there is some room for better power management and/or frequency scaling behavior on Linux to squeeze more performance out of these new highly sought after notebooks. There still is the AMD CPPC CPUFreq patches yet to be revived by AMD engineers, better embracing of Schedutil, and other areas we could see ahead for further improving Zen 2 notebook performance on Linux... Then again, this isn't entirely an AMD problem as we have also seen in the past Windows 10 outperforming Linux on a ~$5000 laptop with Intel Xeon mobile CPU.

As shown in our other Ryzen 7 4700U benchmarks so far, even with the current level of performance on Linux, the Ryzen 7 4700U is performing very well against Intel on Linux and represents a big upgrade in most cases. Further benchmarks are forthcoming.
