Noctua NH-L9a-AM5 Low-Profile Heatsink Works Great For 2U AMD Ryzen AM5 Servers
Noctua NH-L9a-AM5 Low-Profile Heatsink Works Great For 2U AMD Ryzen AM5 Servers
7 Hours Ago - Peripherals - 7 Comments

Noctua at the end of January announced the NH-L9a-AM5 and the all-black NH-L9a-AM5 chromax.black heatsinks as their new ultra low-profile active CPU coolers for the AMD AM5 socket that support AMD's recently announced Ryzen 7000 series 65 Watt CPUs. The height with fan at only 37 mm makes the new NH-L9a-AM5 heatsinks work out very well for small form factor (SFF) builds and for our case at Phoronix an instant hit for running the new AMD Ryzen processors within 2U rackmount enclosures.

17 Hours Ago - Linux Kernel - Parallel CPU Bring-Up - 11 Comments

After the prior kernel patches had stalled in their review process, last week work was revived on x86_64 parallel CPU bring-up for the Linux kernel to help in booting the kernel faster on larger core count desktops and servers. The results have been promising and over the past few days more test results have flowed in along with other positive commentary that will hopefully this time lead to the work ultimately getting upstreamed.

As part of other ongoing performance tests of Intel 4th Gen Xeon Scalable "Sapphire Rapids" testing, I was curious to see how the more well-tuned Linux distributions are performing with the flagship Xeon Platinum 8490H processors relative to the common Ubuntu 22.04 LTS release. Here are those benchmark numbers alongside AMD's flagship Genoa server platform with two EPYC 9654 processors.

As mentioned a few weeks back, Red Hat has been working to arrange a developer "hackfest" to further work out plans and development around HDR display support on the Linux desktop. They are aiming to bring together graphics driver developers, desktop developers, and other Linux stakeholders -- including possibly the likes of Valve -- to work out planning of high dynamic range monitor support over the next year or two for the Linux desktop. That Red Hat HDR hackfest has now been organized to happen in late April.
