Common card · No. 429644

The Radeon 300 series is a series of graphics processors developed by AMD. These GPUs are based on the Graphics Core Next (GCN) microarchitecture, and are produced with TSMC's 28 nm process. The series introduces two new GPUs, "Tonga" and "Fiji", based on GCN 3 microarchitecture; various older GPUs are also rebranded under the series. The Tonga was first introduced with Radeon R9 285 graphics card, and Fiji first with R9 Fury X. Fiji is the first GPU to utilize High Bandwidth Memory (HBM), a type of dynamic random-access memory (DRAM) co-developed between AMD and SK Hynix. Non-Fiji GPUs feature the traditional GDDR5 memory. AMD released the R9 390X on June 18, 2015, the flagship Fury X on June 24, and the Radeon Pro Duo with two Fiji GPUs on a single card, on April 26, 2016.
