AMD last week launched the Radeon PRO W7500 and Radeon PRO W7600 professional graphics cards built on RDNA3. Due to AMD's unique position with their open-source Linux graphics driver stack, I decided to see how these new Radeon professional GPUs compare to FirePro hardware from 13 years ago for the raw performance and power efficiency.

Following Canonical deciding to pull in control of the LXD project and LXD maintainership being limited to Canonical employees, the Linux Containers project has announced the forking of LXD as Incus...

Last year Google decided to deprecate JPEG-XL image support within their Chrome/Chromium web browser. They expressed not enough interest and other factors for so quickly removing JPEG-XL support from their browser. They went ahead and removed the support for this next-gen JPEG standard while now a half-year later they may be having second thoughts...

The Linux kernel's "dimmtemp" driver allows for reporting memory temperatures with capable memory modules and when exposed by the Intel processor's PECI (Platform Environment Control Interface). Currently though the DIMM temperature driver is hard-coded to only allow reporting up to 32 DIMMs while a change queued for Linux 6.6 will extend that limit...

The past several weeks at Phoronix has been very exciting with benchmarking AMD EPYC Genoa-X processors (along with Bergamo) and the incredible uplift delivered by these latest AMD server processors. But for those not yet having the opportunity to test the new EPYC Genoa-X processors locally, those wishing to evaluate the Genoa-X capabilities in the public cloud prior to making an investment in these high-end server processors with 3D V-Cache, or those simply preferring the ease of cloud infrastructure, Azure's new HBv4 series provide an excellent route for leveraging AMD Genoa-X compute capabilities in the cloud. Here are benchmarks of the new Azure HBv4 powered by EPYC Genoa-X compared to prior Azure HPC VMs. The Azure HBv4 performance is outstanding with incredible generational uplift and leading value among Microsoft's HPC-focused VMs.

Back in Linux 6.4 there were Intel HD audio additions for Lunar Lake processors, ACE2.x integration with Lunar Lake has also been worked on as part of the SoundWire support, and also early preparations on the Sound Open Firmware side.

Preventing some modern Windows games from running on Intel Arc Graphics under Linux with Valve's Steam Play has been held up by lack of sparse support within Intel's ANV Vulkan driver. Those limitations will hopefully be overcome with the Intel Xe kernel mode driver when that is mainlined in hopefully the coming months, but for now it's a bit of a sore spot for Intel Linux gamers. A partial workaround though has now been merged for Mesa 23.3 with fake sparse support...

It's been ten years since Intel launched the Haswell processors that were great for the time followed by Broadwell. On the laptop side for Haswell and Broadwell the Panel Self Refresh (PSR) power-savings support has been rather notorious at least on the Linux side. Finally for the Linux 6.6 kernel due out in late 2023, the developers are re-enabling PSR support for these aging laptops...

The just-announced AMD Radeon PRO W7500 and W7600 are working quite well under a fully open-source and upstream graphics driver stack. AMD is making available a new Radeon Software for Linux packaged driver release for those on enterprise Linux distributions, but those living more on the leading-edge and preferring the open-source upstream Linux/Mesa driver experience, I've been testing these new RDNA3 professional offerings and the support is already in place and working out rather well. In this article are some initial tests of the Radeon PRO W7500 and W7600 as well as showing how the performance of the new packaged driver compares to that of using all open-source and upstream GPU driver components.

Earlier this year AMD introduced the RDNA3-based Radeon PRO W7800/W7900 series while today the company is introduced the Radeon PRO W7500 and W7600 series at the lower-end of the professional graphics spectrum...
