PHORONIX --
With the fifteen Linux hardware reviews and 245 original open-source/Linux news stories written by your's truly last month, here is a look back at what was exciting Phoronix readers the most from Google's new KataOS to the release of the speedy Python 3.11, Linux 6.1 taking shaping, and Intel releasing Arc Graphics A750 and A770 graphics cards.

Of the most popular Linux hardware reviews for the past month on Phoronix they included:

Intel Arc Graphics A750 + A770 Linux Gaming Performance
Today the embargo lifts on reviews of the Intel Arc Graphics A750 and A770 graphics cards ahead of their retail availability set for next week. I've had the A750 and A770 at Phoronix the past week and today can share initial performance figures on these Intel DG2/Alchemist discrete graphics cards under Linux with their open-source driver stack.

Intel Core i9 13900K Linux Benchmarks - Performing Very Well On Ubuntu
Last week Intel began shipping their 13th Gen Core "Raptor Lake" processors. As noted in that launch-day article last week, unfortunately I wasn't able to deliver my usual Linux performance review in time due to hitting some DDR5 issues with my test platform, but those have now been resolved with a new Z790 motherboard. So as the first of my Raptor Lake Linux benchmarks, here is a look at how the top-end Core i9 13900K performs against the AMD Ryzen 7000 series on Ubuntu Linux along with the older Intel/AMD processors.

AMD Ryzen 5 7600X Linux Performance
At the end of September when the review embargo lifted I looked at the AMD Ryzen 9 7900X and 7950X for our launch-day Linux testing and that was then followed by the Ryzen 7 7700X Linux review. Since then I received the fourth and final Ryzen 7000 series desktop processor currently available: the AMD Ryzen 5 7600X. The Ryzen 5 7600X is currently AMD's most affordable Zen 4 processor at $299 USD and provides six cores / 12 threads and a boost clock up to 5.3GHz.

Disabling Spectre V2 Mitigations Is What Can Impair AMD Ryzen 7000 Series Performance
Last week I shared some initial numbers how surprisingly when disabling Zen 4 CPU security mitigations can actually *hurt* the Ryzen 7000 series CPU performance. While conventional wisdom and with past Intel/AMD processors yield better performance when disabling the CPU security mitigations, with the Ryzen 9 7950X it was found to be basically the opposite. I have since conducted more tests and using an AMD Ryzen 5 7600X to confirm the earlier results and dig deeper into the data.

Windows 11 vs. Ubuntu Linux Performance Is Very Close On The AMD Ryzen 9 7950X
One of the leading test requests at Phoronix around my AMD Zen 4 Linux benchmarking has been some side-by-side comparisons against Microsoft Windows 11. While older, high core count AMD systems have particularly performed very well under Linux against Windows, with new hardware there is sometimes hiccups and various limitations with the at-launch support especially on the open-source Linux side. So for your viewing pleasure today are some initial AMD Ryzen 9 7950X benchmarks under Microsoft Windows 11 22H2 up against Ubuntu 22.04.1 LTS and a near-final development snapshot of the upcoming Ubuntu 22.10.

AMD Ryzen 9 7950X "Zen 4" Rocks On Intel's Clear Linux
This shouldn't be too surprising to long-time Phoronix readers, but Intel's performance-optimized Clear Linux operating system is yielding great performance with AMD Ryzen 7000 series "Zen 4" processors. Intel's Clear Linux has long shipped HWCAPS support and tuning for AVX-512 and the like to be able to provide optimized libraries when running on their own AVX-512 processors. But with AMD now joining the AVX-512 party -- and Zen 4's AVX-512 implementation performing great -- Intel's Clear Linux distribution is showing leading performance numbers on these new AMD desktop processors.

Python 3.11 Performance Benchmarks Show Huge Improvement
While this summer I ran some early Python 3.11 benchmarks using the development state at the time, given yesterday's Python 3.11 release I ran some fresh performance tests of the official Python 3.11 version against prior Python 3 releases.

AMD Ryzen 9 7950X P-State/CPUFreq Frequency Scaling Performance On Linux
For those wondering the difference using the aging ACPI CPUFreq driver or the newer AMD P-State CPU frequency scaling drivers make for modern Ryzen 7000 "Zen 4" desktops, here are some CPUFreq/P-State driver tests using the Ryzen 9 7950X as well as testing the various governor options and looking at the impact on the CPU power consumption, peak frequency, and thermals too.

Intel Core i5 13600K + Core i9 13900K "Raptor Lake" Linux Preview
Last month Intel announced 13th Gen Core "Raptor Lake" processors while today these processors officially go on sale. Today also marks the review embargo lift with Intel having provided Phoronix with the new Core i5 13600K and i9 13900K processors for Linux testing.

Intel Core i5 13600K Linux Performance
Last week I looked at the Intel Core i9 13900K performance under Linux while today the focus is on the Core i5 13600K. The Core i5 13600K is a 14-core / 20-thread processor (6 P cores + 8 E cores), up from 6 P cores + 4 E cores with the prior generation Core i5 12600K. The Core i5 13600K has a recommended customer price of $319~329, which is indeed being honored among Internet retailers and with robust availability. Here is an initial look at how the Core i5 13600K "Raptor Lake" is running under Ubuntu Linux.
