If you own a computer with a Polaris or Vega-based graphics card from AMD and want to continue receiving drivers with new features and game optimizations, it is time to think about upgrading your rig. An AMD spokesperson
has confirmed to AnandTech that the company is winding down support for its 4th and 5th Gen GCN graphics (Graphics Core Next), also known as AMD Polaris and Vega respectively.
The change does not mean those graphics cards are no longer supported—AMD has yet to move GCN products to its "legacy" list of retired GPUs. However, customers should no longer expect feature parity with newer graphics cards powered by the RDNA architecture. AMD says Polaris and Vega cards are "mature" architectures now receiving drivers from AMD's maintenance driver branch.
The AMD Polaris and Vega graphics architectures are mature, stable and performant and don’t benefit as much from regular software tuning. Going forward, AMD is providing critical updates for Polaris- and Vega-based products via a separate driver package, including important security and functionality updates as available. The committed support is greater than for products AMD categorizes as legacy, and gamers can still enjoy their favorite games on Polaris and Vega-based products.
