# Radeon 500 series

The Radeon 500 series is a series of graphics processors developed by AMD. These cards are based on the fourth iteration of the Graphics Core Next architecture, featuring GPUs based on Polaris 30, Polaris 20, Polaris 11, and Polaris 12 chips. Thus the RX 500 series uses the same microarchitecture and instruction set as its predecessor, while making use of improvements in the manufacturing process to enable higher clock rates.
Third-generation GCN chips are produced on a 28 nm CMOS process. Polaris (fourth-generation GCN) chips (except for Polaris 30) are produced on a 14 nm FinFET process, developed by Samsung Electronics and licensed to GlobalFoundries. Polaris 30 chips are produced on a 12 nm FinFET process, developed by Samsung and GlobalFoundries.

### Supported display standards

The series support DisplayPort 1.4 HBR, HDMI 2.0b, and HDR10 color. Dual-Link DVI-D and DVI-I at resolutions up to 4096×2304 and VGA at up to 2048x1536 are also supported, despite ports not being present on the reference cards, and cards with VGA ports are mostly sold in Eastern Asia exclusively.
