PHORONIX --
Another month in the books, another month closer to the end of the dreadful 2020. It was at least an eventful October with 268 original news articles and another 21 multi-page featured articles and Linux hardware reviews. The content ranged from the continuous Linux kernel advancements to exciting hardware announcements.

As a friendly monthly reminder, if you appreciate all of the Phoronix content each and every day be sure to share it on the likes of Facebook and Twitter.

Linux Developers Discussing Possible Kernel Driver For Intel CPU Undervolting
While the Intel Extreme Tuning Utility (XTU) on Windows allows for undervolting laptop processors, currently on Linux there isn't any Intel-endorsed way for undervolting your CPU should you be interested in better thermal/power efficiency and other factors. But a hypothetical Linux kernel driver could be coming for filling such void.

NVIDIA Doesn't Expect To Have Linux 5.9 Driver Support For Another Month
While NVIDIA is usually quite timely in supporting new versions of the Linux kernel and aim to have out a driver by the end of the release candidates for new series, in the case of the recently minted Linux 5.9 kernel it's taking a lot longer.

Linux 5.10 ARM64 Has A "8~20x" Performance Optimization Forgotten About For Two Years
Last week was the main set of ARM 64-bit architecture updates for Linux 5.10 while today a second batch of changes were sent in for this kernel.

The Failed OUYA Game Console Seeing Work For Mainline Linux Kernel Support
It's been eight years already since the launch of the OUYA game console built atop Android and initially driven up by hype as a new low-cost gaming platform only to turn out to be a commercial failure. Razer bought out OUYA's software assets in 2015 and last year finally shutdown all of the console services. But if you still have the OUYA hardware it soon may start running off the mainline Linux kernel.

Linux 5.10 Will Be Able To Hibernate + Resume Much Faster

Intel Core i7 1165G7 "Tiger Lake" Linux Performance With The Dell XPS 13 9310
Here are our initial benchmarks of Intel Tiger Lake on Ubuntu Linux via the premium Core i7 1165G7 processor. This also appears to be the first public benchmarks of the new Dell XPS 13 9310 laptop that just-launched as the refreshed XPS notebook for Tiger Lake and with Intel EVO certification.

How Intel's Clear Linux Is Competing Against Late-2020 Linux Distributions
As it's been a while since running a fresh Linux distribution comparison with Intel's Clear Linux platform and given all the autumn distribution updates inbound, here is a fresh look at the rolling-release Clear Linux up against a snapshot of Ubuntu 20.10, Fedora Workstation 33 Beta, openSUSE Tumbleweed 20200929, Arch-based Endeavour OS, and Debian Testing from the start of October.

The Most Innovative ~$50 Graphics Card For Linux Users
This ~$50 USD graphics card is open-source friendly, can drive four display outputs simultaneously, passively cooled, and can fit in a PCI Express x1 slot. It's a unique card offering good value especially for those Linux users wanting open-source friendly hardware.

Windows 10 vs. Ubuntu 20.10 Performance With Intel Tiger Lake, AMD Renoir
Stemming from our initial Intel Core i7 1165G7 "Tiger Lake" benchmarks on the Dell XPS 13 9310 last week and then also discovering better single-threaded performance on Ubuntu 20.10, one of the pressing questions was whether this is expected performance on Linux or if it's coming up short of Microsoft Windows for this first tier-one notebook to market with Intel Tiger Lake. So following those earlier tests I proceeded to do a Windows 10 Pro with all available updates comparison on Ubuntu 20.10 with the i7-1165G7. For added context, the same software stack and tests were repeated on an AMD Ryzen "Renoir" notebook.

NVIDIA GeForce RTX 3080 Linux Gaming Performance
After last week exploring the NVIDIA GeForce RTX 3080 Linux GPU compute performance for this Ampere graphics card along with the Blender 2.90 performance, today is a look at the Linux gaming performance for the RTX 3080 both for native games as well as those Windows games running on Linux via Steam Play (Proton).

NVIDIA GeForce RTX 3080 Offers Up Incredible Linux GPU Compute Performance
Yesterday I finally received a GeForce RTX 3080 graphics card from NVIDIA for being able to deliver the first of our Linux benchmarks on the new RTX 30 Ampere series. What is immediately clear is the huge performance uplift for OpenCL and CUDA workloads with the RTX 3080 compared to its predecessors. The raw performance and even performance-per-dollar is staggering out of the GeForce RTX 3080 with the initial tests carried out on Ubuntu Linux. Linux gaming benchmarks will be out in the days ahead but for now is a look at the RTX 3080 compute performance across dozens of benchmarks and going as far back as the GeForce GTX 980 series for comparison.

Intel Xeon vs. AMD EPYC Performance On The Linux 5.8 Kernel
Given that Ubuntu 20.10 will be shipping with Linux 5.8 out-of-the-box along with other autumn 2020 Linux distributions where Linux 5.9 is landing too late, here is a fresh comparison of several different AMD EPYC 7002 "Rome" and Intel Xeon "Cascade Lake" processors on this current stable kernel release for seeing how the performance is standing up as we approach this next round of Linux distribution releases.

Intel Xe Graphics' Incredible Performance Uplift From OpenCL To oneAPI Level Zero To Vulkan
Since picking up the Dell XPS 13 9310 for delivering Tiger Lake Linux benchmarks, most of the focus so far has been about the overall processor performance while in this article is our first deep dive into the Gen12 Xe Graphics performance on Linux with Intel's fully open-source graphics and compute stack. Here is a look at how the Tiger Lake Xe Graphics performance is with the Core i7-1165G7 ranging from OpenGL and Vulkan graphics tests to OpenCL, oneAPI Level Zero, and Vulkan compute tests.

Samsung 980 PRO PCIe 4.0 NVMe SSD Linux Performance
The Samsung 980 PRO PCIe 4.0 NVMe solid-state drives are now available from Internet retailers. For those wondering how these SSDs compare with EXT4 under Linux against other PCIe 4.0/3.0 drives, here are a variety of benchmarks.

Further Exploring The Intel Tiger Lake Core i7-1165G7 Performance On Ubuntu Linux
Last week I published initial benchmarks of the Intel Core i7 1165G7 "Tiger Lake" performance on Linux with the Dell XPS 13 9310 Developer Edition laptop. Of most surprise from those preliminary Linux figures were finding that for some single-threaded workloads the performance was actually worse than the previous generation Ice Lake. Since then I've been running more tests around the clock with some interesting discoveries to note today. It is possible to enhance the single-threaded performance so it's performing better than Ice Lake as would be expected, but comes with lowering the multi-threaded performance compared to the results shared last week.
