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.
