Following the announcement of the AMD Radeon RX 6600 XT last week and ahead of retail availability next week, AMD’s “unboxing embargo” expired today for this new supply-driven RDN2 graphics card. high 1080p frame rates. The card we tested in Linux is the ASRock Phantom Gaming RX 6600 XT.
With today’s embargo lifted just around unboxing the product, we’re not yet allowed to talk about the performance of the Radeon RX 6600 XT but can at least show the map … and needless to say that ‘AMD wouldn’t have sent this graphics card to us if the Radeon RX 6600 XT wasn’t running Linux or had major issues. So that alone speaks to Linux support, but of course more on that next week.
As a reminder, the Radeon RX 6600 XT launches at $ 379 USD given the current graphics card climate and focuses on delivering superior 1080p performance. The RX 6600 XT based on the previous announcement is expected to compete with the NVIDIA GeForce RTX 3060 series and offer a much bigger improvement than the RX 5600 XT or RX 5700 Navi cards.
Support for Radeon RX 6600 XT Linux is codenamed “Dimgrey Cavefish”. Dimgrey Cavefish’s open source work dates back to September 2020 and with the kernel-side AMDGPU driver created in Linux 5.11 and has seen improvements in subsequent kernels. Likewise, Mesa 20.3 added Dimgrey Cavefish with RDNA2 / Dimgrey enhancements in Mesa 21.x releases. But whatever version of Linux kernel and Mesa you’re on, AMD released new Radeon Software for Linux drivers on launch day to support the new GPUs on enterprise Linux distributions. Long story short, you can expect Linux driver support for the RX 6600 XT with full details next week.
