Qualcomm Snapdragon X1 Elite GCC vs. LLVM Clang Compiler Performance

6. Červen 2025 - 16:25
Since recently picking up a Qualcomm Snapdragon X Elite laptop for Linux testing now that the Linux support is starting to evolve into better shape (albeit still with many rough corners limiting the daily usability of such devices with Linux), one of the areas I was curious about was looking at the performance of Linux binaries with GCC vs. LLVM Clang. Here are some benchmarks for those wondering how the GCC and Clang compilers are competing on the Snapdragon X Elite with the Oryon CPU cores.

FreeBSD Developers Deciding What To Do For WiFi With FreeBSD 15: Stable Or Unstable

5. Červen 2025 - 15:35
FreeBSD developers have been working a lot on their wireless/WiFi driver support in recent months as part of their broader initiative for improving their operating system support for laptops. While a lot of progress has been made on seeing more modern WiFi support and recent WiFi chipsets being enabled, it's still not complete and that puts FreeBSD 15 in a tough position. FreeBSD 15 is set to be released later this year and will likely declare their wireless support as "unstable" to allow time for making future breaking modifications...

AMD Radeon 8050S "Strix Halo" Linux Graphics Performance

5. Červen 2025 - 11:31
Last month I began the much anticipated AMD Strix Halo Linux benchmarking at Phoronix by testing the top-end Ryzen AI Max+ PRO 395 that features 16 cores / 32 threads and the very impressive Radeon 8060S integrated graphics. Coming in one step below that flagship Strix Halo SoC is the Ryzen AI Max (PRO) 390 with Radeon 8050S graphics. Coming out today on Phoronix - coincidentally timed for the 21st birthday of Phoronix.com - is the first benchmarks of the Ryzen AI Max PRO 390 along with the Radeon 8050S graphics.

AMD Ryzen AI Max 390 Performance - 12-Core Strix Halo

5. Červen 2025 - 11:30
For some very fun Linux benchmarking on this 21st anniversary of starting Phoronix is looking at the Ryzen AI Max (PRO) 390 Linux performance, the 12-core Strix Halo SoC with Radeon 8050S Graphics. While there have been various benchmarks of the AMD Ryzen AI Max+ (PRO) 395 in recent weeks on Phoronix and other publications, the other Ryzen AI Max "Strix Halo" SoCs haven't been as widely seen in the industry yet. The 12-core Ryzen AI Max PRO 390 was tested within another HP ZBook Ultra G1a for a very interesting look at the high-end/premium Linux laptop/workstation performance.

Marking 21 Years Of Covering Linux Hardware

5. Červen 2025 - 11:00
Phoronix has made it another year. Today marks 21 years since I started Phoronix.com with a focus on providing Linux hardware reviews. Linux hardware support is a night and day difference then to today as is the overall ecosystem with all the major hardware vendors these days having some -- often significant -- levels of interest in Linux support. No longer is it typically a worry of whether your mouse, 56K modem, WiFi adapter, or other basic peripherals working but most often just a matter of how well the performance is on Linux, whether there is LVFS/Fwupd firmware updating support, and if other non-show-stopping features are supported. We still haven't managed the "year of the Linux desktop" but it's been wild with Chrome OS and Android being based on Linux, Linux coming to dominate the server world, Linux being ubiquitous to cloud computing, and Valve revolutionizing the Linux gaming space...
