AMD recently launched the Radeon RX 6500 XT graphics card for the $199 USD price point. While built on the current-generation RDNA2 architecture, this graphics card was widely panned for its price while only offering 4GB of video memory, limited to PCIe x4 bandwidth, and performance similar to the years-old Polaris GPUs. While all the major benchmarks online to this point have been under Windows, here is a look at how the AMD Radeon RX 6500 XT is performing under Linux.

Prominent Mesa developer Jason Ekstrand who formerly led Intel's "ANV" Vulkan driver effort and being one of their open-source driver developers originally involved with the NIR intermediate representation work wrote a detailed and excellent blog post outlining its successes eight years running. While it still gets brought up into discussions from time to time (including quite recently stemming from a RISC-V graphics thread) why Mesa doesn't use LLVM IR or SPIR-V directly as its intermediate representation, NIR continues as a striking success and used by all major Mesa drivers...

Since Intel's Alder Lake launch one of the test requests to come in a few times has been about the Intel P-State CPU frequency scaling driver and how its performance differs with the various governor choices available for altering the CPU frequency scaling behavior. Now that Linux 5.16 stable is out and running in good shape on Alder Lake, here are some Core i9 12900K benchmarks looking at various CPU frequency scaling choices and their impact on raw performance as well as CPU thermals and power consumption.

This will hopefully be the year that PipeWire becomes commonplace on the Linux desktop across all major distributions for audio/video stream management.

Microsoft has kept to updating CBL-Mariner publicly on a monthly basis and continuing to make it easier to test out and enhance its usefulness. Last night they published their January 2022 build of Microsoft's Linux operating system...

The DirectFB library had been a popular option for embedded systems in running off the Linux frame-buffer to avoid the full overhead of an X11 server. But a number of years ago DirectFB disappeared and ultimately stopped being maintained. Meanwhile Wayland has been making lots of inroads into mobile/embedded and areas once popular for DirectFB use. But now it turns out DirectFB2 is in development as a fork of the original DirectFB...

The Celeron G6900 is a dual-core Alder Lake processor with a suggested customer price of $42~52 USD (though for the limited quantities available, I ended up paying $69). Curiosity got the best of me for seeing how well this lowest-end Alder Lake part performs under Ubuntu Linux.
