AMD Radeon RX 590

8 GB GDDR5 · 256-bit · 2,304 cores

The fastest card of AMD's Polaris-based Radeon RX 500 series, released in November 2018 for 1080p gaming. It uses the Polaris 30 chip, a 12 nm version of the Polaris 20 GPU in the RX 580 with the same 36 compute units, which allowed higher clock speeds. A China-only RX 590 GME later reused the 14 nm Polaris 20 chip under a similar name.
