When taking the geometric mean of all these benchmark results, the Windows 10 Professional performance was the same as Windows 10 Enterprise for this Threadripper 3970X testing, unlike the Enterprise advantage we've seen on the larger Threadripper 3990X. The slowest of the eight Linux distributions tested was the Ubuntu 20.04 development snapshot, but that still came out to be 9.5% faster than Windows 10. The fastest Linux distribution was Clear Linux on the Threadripper 3970X with a 19% over Windows in these cross-platform benchmarks. Following Clear Linux with a strong showing was the new rolling-release CentOS Stream.

  There's lots of stuff here, but also a ton of release process data changes.
  We've got changes all over the tree, but aco and anv are leading the way in

• mesa 20.0.0-rc3

  Hi list,
  
  Mesa 20.0.0-rc3 is now available. This is a much smaller release than last time,
  things seem to be slowing down nicely, and the number of opened issues/MRs
  against the 20.0 release milestone is 2; I'm hopeful that means we can have the
  20.0 release next week, and begin the normal release process without a dozen
  RCs.
  
  There's a bit of everything in here, gallium, freedreno, vulkan overlays, anv,
  radeonsi, svga, intel common, aco, nir, swr, and panfrost, but no on thing
  dominates the changes, which I like a lot.

• Mesa 20.0-RC3 Released Along With Mesa 19.3.4 As The Latest Of The Stable Series

  On the stable front, Mesa 19.3.4 is out as the newest point release in this driver series from Q4'2019. Mesa 19.3.4 has various RADV and ANV Vulkan driver fixes, a few Vulkan overlay fixes even, several AMDGPU winsys fixes, RadeonSI is now disabling display DCC over issues, and there are also a number of Valve ACO back-end fixes too. Overall, Mesa 19.3.4 is a pretty hefty stable update particularly for Intel ANV and Radeon RADV Vulkan driver users.

Here are some fresh numbers looking at the current performance of various AMD EPYC 7002 "Rome" processors up against Intel Xeon Cascade Lake processors when using an Ubuntu 20.04 LTS development snapshot and also upgrading to Linux 5.5 as the latest stable kernel. Beyond raw performance, power efficiency and performance-per-dollar for these different server CPUs are being compared as well for these sub-$5000 processors.

Ahead of the Ubuntu 20.04 long-term support release this spring and being curious how the latest AMD EPYC and Intel Xeon CPUs are competing with a bleeding-edge software stack also including Linux 5.5, this fresh benchmark comparison was performed. The single-socket tests carried out for this article included the...

For those that may be looking to run an air-cooled AMD Ryzen 9 3950X especially in a rack-mount 4U chassis, here are some recent results I did from some testing using a Noctua NH-U9S with two 92mm fan configuration. Additionally, these results contain performance metrics from both CPUFreq Ondemand vs. Performance governors as an additional point of interest.

These results are for reference purposes of the Noctua NH-U9S in a dual fan setup for this 16-core / 32-thread 3.5GHz (4.7GHz boost) CPU rated with a 105 Watt TDP.
