HP ZBook Ultra G1a: An Incredible, Powerful Mobile Workstation Powered By AMD's Ryzen AI Max

Phoronix - 11. Červen 2025 - 21:00
Over the past month I have been testing out the HP ZBook Ultra G1a powered by AMD Ryzen AI Max+ PRO Strix Halo. Simply put: WOW! I don't remember the last time I have been so fascinated by a laptop SoC from its incredible performance generationally and even compared to existing AMD SoCs within the Ryzen AI 300 series and outright dominating against the Intel Lunar Lake for its Xe2 integrated graphics. The HP ZBook Ultra G1a thanks to AMD Strix Halo offers an incredibly potent integrated GPU and allowing up to 16 cores / 32 threads offers immense CPU performance too. HP packages Strix Halo up into a very well built, mobile workstation oriented laptop design to create an amazing laptop. It's a reliable laptop with captivating performance but does carry a high price tag but with good Linux support too except for one caveat.

Posted today was an experimental patch providing very early support for the AMD Instinct MI300 series hardware with the GCC compiler...

Linux 6.15 Delivering Some Performance Gains On AMD EPYC For AI, HPC & Databases

Phoronix - 10. Červen 2025 - 19:00
The Linux 6.15 kernel cycle started off a bit rough with a heavy hitting performance regression spotted and then fixed but to only then discover another Linux 6.15 performance regression affecting modern AMD CPUs. Fortunately those issues were cleared out in time for the recent Linux 6.15 stable release. Linux 6.15 stable is looking good especially on 5th Gen AMD EPYC "Turin" servers with some recent benchmarks showing some modest gains over the Linux 6.14 kernel.
