Measuring The Performance Cost To AMD Memory Guard With Ryzen AI PRO CPUs

12 juin 2025 à 12:00
While the AMD Ryzen AI Max+ PRO 395 and Ryzen AI Max+ 395 are very similar processors just as the Ryzen PRO processors are to other non-PRO parts, one of the differences with the AMD PRO Technologies come down to AMD Memory Guard providing full system memory encryption. From the HP BIOS with the ZBook Ultra G1a there is a convenient toggle for this full memory encryption support and thus I decided to carry out some benchmarks to measure the performance cost to this memory encryption feature on this AMD Strix Halo SoC.

Platform Profile Power/Performance Impact For ThinkPad T14s G6 + AMD Ryzen AI 7 PRO 360

12 juin 2025 à 08:00
Back in April I published Linux benchmarks of the Lenovo ThinkPad T14s Gen 6 with the AMD Ryzen AI 7 PRO 360 SoC. Some follow-up benchmarks I did back then that I have been meaning to publish is looking at the ACPI Platform Profile impact on performance and power for this ThinkPad laptop under Linux. Here are those numbers...

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

11 juin 2025 à 20:00
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.

DragonFlyBSD Updates Its Graphics Drivers With New GPU Support But Still Years Behind

11 juin 2025 à 13:00
DragonFlyBSD has updated its Direct Rendering Manager (DRM) kernel graphics/display driver code that it ports over from what's available in the upstream Linux kernel. The latest revision to the DragonFlyBSD kernel graphics driver code enables support for some new hardware platforms but remains woefully behind the latest generation dGPUs/iGPUs and what is found in the upstream Linux kernel...

Taking AMD Ryzen AI Max Performance To The Max With Clear Linux & CachyOS

11 juin 2025 à 09:00
With the HP ZBook Ultra G1a Strix Halo laptop sporting the AMD Ryzen AI Max+ PRO 395 with Radeon 8060S Graphics it offers incredible performance potential as shown in my many benchmarks over the past month on Ubuntu Linux. But if wanting to push the Ryzen AI Max even further, with performance-optimized Linux distributions like CachyOS and Intel's Clear Linux it's possible to tap some additional performance out of this 16-core Zen 5 laptop.

Experimental Patch Brings Very Primitive AMD Instinct MI300 Support To GCC Compiler

10 juin 2025 à 22:00
With AMD continuing to be focused on their AMDGPU LLVM compiler back-end for their GPU compiler needs from compute to graphics shaders, the AMD GPU/accelerator hardware support within the GNU Compiler Collection "GCC" has long taken a backseat and left to third-party firms to implement. 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

10 juin 2025 à 18:00
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.
