AMD Ryzen 4000 Renoir Zen 2 APUs see huge gains on Ubuntu 22.04 LTS, not so for Intel

Last year in December, we learned that AMD's Zen 3-based Ryzen 5000 APUs (codenamed "Cezanne" and "Lucienne") were getting some really impressive gains on Linux 5.16. And although Ubuntu 22.04 LTS isn't based on that as it instead uses Linux kernel 5.15, it looks like AMD has done well here too as the latest testing from Phoronix finds that Ryzen 4000 APUs codenamed "Renoir" have had excellent gains on Ubuntu 22.04 LTS as compared to Ubuntu 20.04.4 LTS.

The gains on the AMD platform are also far more pronounced than what we get on the Intel 10th Gen Comet Lake processor indicating that a lot of long overdue optimization has finally been made on the Ryzen side.

For this test, a couple of OnLogic fanless edge embedded PCs were used. On the Intel side, we have the OnLogic Helix 500 with the Core i7-10700T eight core, sixteen threaded (8C/16T) 35W CPU. Meanwhile, on the AMD side, the OnLogic ML100G-41 with the 8C/16T Ryzen 4800U 15W APU was used.

First up, we have the integrated graphics processor (iGP) test and in some of the benches here, the numbers on the 22.04 LTS side are significantly better for the AMD part. Meanwhile, the Intel Comet Lake i7 SKU loses performance here.

Up next, we have some tests that leverage the CPU and here too, the performance boost on Ubuntu 22.04 LTS systems for the 4800U are very notable and significant:

Overall, the AMD Ryzen 4800U Renoir APU has gained nearly 8.7% on Ubuntu 22.04. Meanwhile the improvement on the Intel Comet Lake Core i7-10700T is much more modest at just 0.7%.
