4th Generation GCN Architecture Improvements/Features

 

AMD has had four generations of its GraphicsCore Next architecture, with the first GCN architecture featuring DX11 support, OpenGL 4.2, OpenCL 1.2, hardware tessellation support, and more. As time went on, AMD added new features like DX11.1, DX12, Mantle, Vulkan, LiquidVR, Asynchronous Compute, and Virtual Super Resolution.

The second generation GCN architecture provided improved compute task scheduling, AMD TrueAudio technology, OpenCL 1.2 and OpenGL 4.3 support, and more. It also saw FreeSync support, DX12, Mantle, Vulkan, LiquidVR, Async Compute, and more over time.

The third-generation GCN architecture included support for High Bandwidth Memory (HBM) which was found in the Fiji architecture on the Radeon R9 Nano, R9 Fury, and R9 Fury X cards. The third-gen GCN architecture also included improved tessellation performance, Delta Color Compression, a hardware scheduler (HWS) for Asynchronous Compute, native FP16/Int16 shader ops (APU), and more.

But now we're at the fourth-gen GCN architecture with Polaris, and we have improved geometry processing, LiquidVR API for variable resolution rendering, shader instruction pre-fetch and enhanced buffering, real-time and prioritized Async Compute with spatial and temporal scheduling, and more. AMD has continued to evolve its GCN architecture, which is great to see.

Radeon's Asynchronous Compute support has been extensive.
