AMD EPYC 7642 Benchmarks

Since the AMD EPYC 7002 series “Rome” launch at the beginning of August, it’s been known how AMD’s top-end (aside from the newly-announced EPYC 7H12) EPYC 7742 easily outperforms the Intel Xeon Platinum 8280 in most real-world benchmarks. The EPYC 7742 not only outperforms the Xeon Platinum 8280 in raw performance but also at a significantly lower cost and it gets even better with the EPYC 7642. We have been testing the EPYC 7642 48-core processors and even there the performance is generally ahead of a Xeon Platinum 8280 while being about half the cost of that flagship non-AP Intel Xeon Scalable Cascadelake processor.

NetworkManager Will Now Roam For WiFi Signals More Aggressively

NetworkManager has shifted its threshold for a weak WiFi signal for when to begin searching for other WLAN networks. Up to now NetworkManager used a -80dBm threshold for when to roam for other network signals while now that has changed to find hopefully stronger network signals sooner…

Clear Linux vs. Ubuntu 19.10 Video Encoder Performance On The Core i9 9900K

Often when doing cross-distribution benchmarks, readers often comment on the performance of Clear Linux particularly for video encoding use-cases as surprisingly different from other distributions. Some argue that it’s just over the default CPU frequency scaling governor or compiler flag defaults, so here is a look at that with Ubuntu 19.10 daily benchmarked against Clear Linux…

GNOME 3.34 Should Be Hitting Clear Linux "Soon-ish"

For those anxious to make use of GNOME 3.34 with its many own performance improvements atop Intel’s performance-optimized Clear Linux rolling-release distribution, it looks like the wait is still going on for a few more days but is coming “soon-ish” to the platform…

Running The AMD "ABBA" Ryzen 3000 Boost Fix Under Linux With 140 Tests

Last week AMD’s AGESA “ABBA” update began shipping with a fix to how the boost clock frequencies are handled in hopes of better achieving the rated boost frequencies for Ryzen 3000 series processors. I’ve been running some tests of an updated ASUS BIOS with this adjusted boost clock behavior to see how it performs under Linux with a Ryzen 9 3900X processor.

Valve's ACO Shader Compiler For The Mesa Radeon Vulkan Driver Just Landed

It was just two days ago that Valve’s performance-focused “ACO” shader compiler was submitted for review to be included in Mesa for the “RADV” Radeon Vulkan driver. Just minutes ago that new shader compiler back-end was merged for Mesa 19.3…

Performance-Boosting DFSM Support Flipped On & Off For RADV Vulkan Driver

Back in July of last year the RADV Vulkan driver enabled primitive binning and DFSM for this open-source Radeon Vulkan driver. Well, it thought it enabled DFSM support and paired with the binning did yield a minor performance benefit at the time for Raven Ridge APUs. But now it turns out the DFSM support wasn’t properly wired up and is now addressed but is currently introducing a performance regression…
