While Intel's upcoming Core Ultra Series 2 "Lunar Lake" laptop processors are doing away with Hyper Threading (HT) and instead focusing more on additional E cores. AMD has asserted Simultaneous Multi-Threading (SMT) is still beneficial and supported across both their Zen 5 and Zen 5C cores. For those curious about the SMT performance and power efficiency impact, here are some SMT on/off comparison benchmarks using the Ryzen AI 9 HX 370 "Strix Point" laptop processor.

Like most modern Intel and AMD laptops, the new ASUS Zenbook S 16 models for the AMD Ryzen AI 300 series "Strix Point" support ACPI Platform Profiles for allowing the system platform behavior to be modified depending upon whether you are seeking maximum performance, balanced (default), or power savings/efficiency. With the Ryzen AI 9 365 and Ryzen AI 9 HX 370 testing I have been doing thus far it's been on the default balanced mode (along with other laptops being compared) while in this article is a look at the Ryzen AI 9 HX 370 performance impact on the ASUS Zenbook S 16 UM5606WA when trying the other platform profile options.

Mike Blumenkrantz of Valve's Linux graphics driver team has recently begun pushing changes to the Mesa 3D graphics code-base as part of "The Juiciest Refactor Ever". After merging the first of the patches last week, this week has brought more code for this juicy refactoring...

For those intrigued by Ikey Doherty's work in recent times on Serpent OS as a new from-scratch Linux distribution that makes use of lots of tooling, Ikey is kicking off August by releasing the first pre-alpha image of this Linux OS...

Now that I am through with my testing of the initial Ryzen AI 9 HX 370 and Ryzen AI 9 365 Linux performance benchmarking and support exploration, I've begun diving in to other areas of the Linux support/performance for these Zen 5 "Strix Point" SoCs. The area for a quick look today is with the yet-to-be-merged AMD Heterogeneous Core Topology patches...
