Last week I began posting Linux benchmarks of the flagship “Strix Halo” SoC, the AMD Ryzen AI Max+ PRO 395 with powerful Radeon 8060S graphics using the HP ZBook Ultra G1a laptop. Both the CPU and GPU results for the data published thus far have been mighty impressive and done at the Ubuntu Linux defaults… But the Ryzen AI Max+ 395 within the ZBook Ultra G1a can be pushed even further by leveraging the ACPI Platform Profiles capabilities. In this article is showing how much further performance — and the power costs — can be achieved out of this AMD Strix Halo SoC when leveraging the HP Power Profiles as well as the power efficiency for those wanting to run the SoC instead in the “power saver”https://www..com/”low power” configuration.
As shown on various modern notebooks the past few years, ACPI Platform Profiles can make for some nice performance boosts or power-savings/efficiency improvements depending upon your preference and how well tuned the platform profiles are by the given hardware vendor. Today’s article is looking at the impact of changing the Platform Profile option on the HP ZBook Ultra G1a with the AMD Ryzen AI Max+ PRO 395 SoC.
The Strix Halo / ZBook Ultra G1a benchmarks to date on Phoronix were all done in the default “balanced” platform profile configuration as used out-of-the-box on the laptop. Today’s article adds in the performance and SoC power results when switching to the “performance” profile for peak performance and similarly the impact of restricting the SoC capabilities within the “power saver”https://www..com/”low power” mode for those wanting to extend the battery life, lower the thermals, or similar.
Ubuntu 25.04 with the Linux 6.14 kernel remained the default Linux configuration for all of these tests of the performance and power saver modes alongside the default balanced configuration. For additional perspective, the Linux laptop benchmark results from the Core Ultra 7 258V “Lunar Lake” with the Lenovo ThinkPad X1 Carbon Gen 13 and Framework Laptop 13 with AMD Ryzen AI 9 HX 370 were left as part of the comparison for additional perspective into the power/performance impact of Strix Halo. For more Linux laptop benchmarks see the aforelinked Ryzen AI Max+ articles from last week. Plus other HP ZBook Ultra G1a Linux benchmarks remain ongoing at Phoronix.
