History
Predecessor AMD Radeon Rx 300 Series

The Radeon Rx 400 is an upcoming brand of graphics cards made by AMD. These cards will be the first to feature the Arctic Islands GPUs, using the new 14 nm[1] FinFET manufacturing process and second generation High Bandwidth Memory (HBM),[2] along with support for both HDMI 2.0a and DisplayPort 1.3 HBR3.[3] It is expected that the cards will be released in Q2/Q3 of 2016.[4]

The Arctic Islands family will include three new chips in the Graphics Core Next (GCN) family (Greenland, Ellesmere and Baffin),[5][6] and will feature a new GPU microarchitecture called Polaris.[7] Polaris implements version 1.3 of the Graphics Core Next instruction set, and shares commonalities with the previous GCN microarchitectures. There will initially be two variants, Polaris 10 (Ellesmere) and Polaris 11 (Baffin).

According to AMD, their prime target with the design of Polaris was energy efficiency: Polaris 10 is initially planned to be a mid-range chip, to be featured in the upcoming R9 480, with a TDP of around 110-135W[8] compared to its predecessor R9 380's 190W TDP. Despite this, the Polaris 10 will run the latest DirectX 12 games "at a resolution of 1440p with a stable 60 frames per second."[8] The low-end Polaris 11 will have a TDP of only 50W.[8]

Polaris 10 may feature 2304 stream processors across 36 Compute Units (CUs), and support up to 8GB of GDDR5(X) memory on a 256-bit memory interface. The GPU is set to replace the mid-range Tonga segment of the Radeon M300 line. Polaris 11, on the other hand, is to succeed the "Curacao" GPU which powers various low-to-mid-range cards. It will likely feature 1024 stream processors over 16 CUs, and is expected to be capable of having 4GB of GDDR5 memory on a 128 bit memory interface.[9]
