PHORONIX --
Another month of the tumultuous year that is 2020 is now in the books... At least in November were several exciting hardware announcements to help pass the time along with the exciting evolution of open-source software.

During November were the launches of the AMD Radeon RX 6800 series graphics cards to much success along with the AMD Ryzen 5000 "Zen 3" processors, both of which generated much immense interest thanks to the open-source support and great Linux performance. There was also the Apple M1 launch that is interesting from the ARM64 performance perspective albeit not yet compatible with bare metal Linux. There was also the continued growth of Proton/VKD3D related efforts to improve Linux gaming, WebP2 going into public development, moving closer to Debian 11, and other exciting Linux software advancements.

Looking ahead to December is yet more exciting hardware to come and many interesting benchmarks already in the works.

AMD Radeon RX 6800 Series Linux Performance
Today is the big day: Big Navi is shipping! This also means we can talk at length finally about the Linux support and performance for the Radeon RX 6800 series and how well they perform for Linux gaming. Here is a look at the Linux driver state for these initial RDNA 2 graphics cards and their performance capabilities with the multiple different open-source driver stacks available.

Apple M1 ARM Performance With A 2020 Mac Mini
For those curious about the hardware potential out of Apple's in-house M1 processor powering new Mac Book Pros and Mac Mini, for the past week we have been running benchmarks of this ARM-based processor and have a number of benchmarks to share today looking at how the performance compares to prior Intel-powered Macs along with the Rosetta 2.0 performance for running x86_64 binaries on ARMv8.

AMD Ryzen 9 5900X + Ryzen 9 5950X Dominate On Linux
The AMD Ryzen 9 5900X and Ryzen 9 5950X are hands-down incredible winners. While processor company marketing claims are sometimes dubious and not necessarily relevant to Linux users and their open-source workloads/software, after testing the Ryzen 9 5900X and 5950X the past several weeks the performance has been incredibly compelling with significant single and multi-threaded performance uplift over Zen 2 and easily thrashing Intel's current desktop offerings with over 200 benchmarks conducted for launch-day.

Benchmarking The Raspberry Pi 400 - A Raspberry Pi Keyboard Computer
The Raspberry Pi Foundation is today announcing a new and unexpected single board computer: the Raspberry Pi 400. It's more of a single-keyboard computer that offers slightly higher performance than the Raspberry Pi 4.

AMD Ryzen 5 5600X Linux Performance
Following yesterday's launch-day AMD Ryzen 9 5900X/5950X benchmarks that showed the utter domination of Zen 3 carrying over just fine in the Linux realm, today we are looking at the performance of the Ryzen 5 5600X on Ubuntu against other Intel/AMD processors. The Ryzen 5 5600X is AMD's new $299 USD part that offers six cores / twelve threads and incredible uplift still over Zen 2 / Zen+ processors while outperforming Intel's Comet Lake competition.

Radeon RX 6800 Series Has Excellent ROCm-Based OpenCL Performance On Linux
While Radeon Open eCosystem (ROCm) support wasn't a focus for the initial Radeon RX 5000 "Navi" graphics cards by AMD engineers, that is fortunately changing for both the RX 5000/6000 series moving forward. With the Radeon RX 6800 series there is at-launch support available with working OpenCL provided by the "ROCr" (runtime) path in their packaged driver. Now that we have looked at the Radeon RX 6800 Linux gaming performance here are some initial OpenCL compute benchmarks between NVIDIA and AMD Radeon on Linux.

AMD Ryzen 7 5800X Linux Performance
Over the past week we have looked at the AMD Ryzen 9 5900X/5950X Linux performance as well as that of the lower-end -- but still very powerful -- Ryzen 5 5600X. Today we are striking in the middle in looking at the last Zen 3 CPU model for the moment: the Ryzen 7 5800X. The AMD Ryzen 7 5800X is a $449 USD processor that is packing eight cores / sixteen threads, a 3.8GHz base clock. 4.7GHz boost clock, 32MB L3 cache, and has a 105 Watt TDP.

AMD Ryzen 9 5900X/5950X Linux Gaming Performance
After just publishing the results of 200+ Linux benchmarks under many diverse workloads for the Ryzen 9 5900X and Ryzen 9 5950X we see the 16~20% performance lift is very real and very broad from obscure open-source niche software through high profile programs... What about the Linux gaming performance? This article offers a first look at the Ryzen 9 5900X/5950X Linux gaming performance compared to Zen 2 and the Core i9 10900K while being the first of several Linux gaming performance articles coming out this month.

Radeon RX 6800 Series Performance Comes Out Even Faster With Newest Linux Code
Last week we delivered AMD Radeon RX 6800 / RX 6800 XT Linux benchmarks and the performance was great both for Linux gaming as well as the OpenCL compute performance. But for as good as those Big Navi numbers were on the open-source Linux graphics driver stack, they are now even better.

Tiger Lake + Renoir On Ubuntu Linux For Battery vs. AC Performance
Given the recent Intel presentation alleging AMD Ryzen laptop performance being worse on battery relative to the AC vs. battery performance seen with Intel EVO notebooks featuring Tiger Lake processors, I ran a mini comparison on my side to see whether there is any merit to Intel's information when testing under Ubuntu Linux.
