AMD Radeon RX 6500 XT Linux Performance

Phoronix - Mon, 01/31/2022 - 20:14
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.

Numerous Linux/X11 Display Drivers Can No Longer Even Properly Build

Phoronix - Mon, 01/31/2022 - 13:00
While many Linux enthusiasts like to cite Linux's stellar support for older hardware platforms, in reality that isn't always the case. For instance with many old X.Org user-space mode-setting drivers for powering old graphics cards at least for display purposes, they can no longer even build with with modern toolchains / software components. Given the lack of bug reports around such issues, there are very likely few users trying some of these vintage hardware combinations...
