One step below AMD's current top-end EPYC 7601 server processor is the EPYC 7551. The EPYC 7551 costs around $800 USD less than the 7601 while still being a 32 core / 64 thread part but with slightly lower clock frequencies. In this article is a look at the EPYC 7251 / 7351P / 7401P / 7551 / 7601 Ubuntu Linux performance compared to various Intel Xeon CPUs in our lab.

There's been a theme recently with the open-source graphics drivers of working on priority scheduling support from AMDGPU priority scheduling for VR use-cases and tied into RADV to Intel also allowing context priority support that in turn is exposed through EGL. The Freedreno driver has also been working on a context priority implementation...

For many years Linux storage enthusiasts have dreamed of having the ZFS file-system part of the mainline Linux kernel. But since Oracle acquired Sun Microsystems that outlook has looked much more bleak that they would re-license the ZFS kernel code under a license compatible with the upstream GPLv2 Linux kernel. But an Oracle engineer presented today that the ZFS Linux dream might still come true...

Yesterday I posted some fresh benchmarks of the RX Vega between the AMDGPU+RadeonSI/RADV open-source vs. AMDGPU-PRO drivers, which showed the pure open-source driver stack performing admirably well for the latest-generation AMD graphics architecture and the community-driven RADV Vulkan driver was even performing nicely. Due to how well RADV has matured during the Mesa 17.3 cycle, here are some benchmarks using a Radeon RX 580 "Polaris" graphics card showing off its more mature support for Vulkan.
