With the AMD Zen 5 generation, the timing is interesting where it's not the desktop processors launching first but happens to be in the form of AMD Ryzen AI 300 series laptops. With the last minute delay of the Ryzen 900 series by 1~2 weeks, the embargo lift for the Ryzen AI 300 series is timed for this Sunday morning where I can now present the first AMD Zen 5 Linux benchmark results. And with being the first Zen 5 chip in my lab, I have been pushing it hard... Here is an extensive look at the ASUS Zenbook S 16 I received with the Ryzen AI 9 HX 370 current flagship SoC compared to a variety of other AMD and Intel laptop models. The focus was on both the raw performance and the package performance-per-Watt for the overall power efficiency of this Zen 5 SoC. And with it being the first Zen 5 hardware in the lab, I didn't limit the selection to just conventional laptop workloads but also explored the performance characteristics for various other workloads of interest to diverse Linux users and for an idea of the HX 370 potential or similar Zen 5 chips appearing in thin client / edge / IoT type devices. This initial taste of AMD Zen 5 has me extremely excited about the performance potential of the upcoming Ryzen 9000 series and EPYC Turin processors.
While the upcoming AMD Ryzen 9000 series desktop processors continue to make use of RDNA2 graphics, with the Ryzen AI 300 series shipping today in notebooks there are RDNA3.5 graphics being introduced alongside the Zen 5 CPU cores and upgraded Ryzen AI XDNA2 NPU. While just an evolution of RDNA3, the initial benchmarks of RDNA3.5 graphics with the Ryzen AI 9 HX 370 are looking rather promising for both the raw graphics performance as well as the power efficiency. The Radeon 890M RDNA3.5 graphics are working on Linux when using a new enough software stack.
