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.

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...
