Real-time hardware accelerated ray tracing is a new feature for RDNA 2 which is handled by a dedicated ray accelerator inside each CU. [10] Ray tracing on RDNA 2 relies on the more open DirectX Raytracing protocol rather than the Nvidia RTX protocol.
The decision to move to a chiplet-based GPU microarchitecture was led by AMD Senior Vice President Sam Naffziger who had also lead the chiplet initiative with Ryzen and Epyc. [6] The development of RDNA 3's chiplet architecture began towards the end of 2017 with Naffziger leading the AMD graphics team in the effort. [7]
Die shot of the RX 5500 XT's RDNA GPU. The architecture features a new processor design, although the first details released at AMD's Computex keynote hints at aspects from the previous Graphics Core Next (GCN) architecture being present for backwards compatibility purposes, which is especially important for its use (in the form of RDNA 2) in the major ninth generation game consoles (the Xbox ...
On 24 November 2015, AMD released a new version of their graphics driver following the formation of the Radeon Technologies Group (RTG) to provide extensive software support for their graphics cards. This driver, labelled Radeon Software Crimson Edition, overhauls the UI with Qt , resulting in better responsiveness from a design and system ...
Note that ATI trademarks have been replaced by AMD trademarks starting with the Radeon HD 6000 series for desktop and AMD FirePro series for professional graphics. Codename – The internal engineering codename for the GPU. Launch – Date of release for the GPU. Architecture – The microarchitecture used by the GPU. Fab – Fabrication ...
CDNA (Compute DNA) is a compute-centered graphics processing unit (GPU) microarchitecture designed by AMD for datacenters. Mostly used in the AMD Instinct line of data center graphics cards, CDNA is a successor to the Graphics Core Next (GCN) microarchitecture; the other successor being RDNA (Radeon DNA), a consumer graphics focused microarchitecture.
The Navi GPUs are the first AMD GPUs to use the new RDNA architecture, [6] whose compute units have been redesigned to improve efficiency and instructions per clock (IPC). It features a multi-level cache hierarchy, which offers higher performance, lower latency, and less power consumption compared to the previous series.
The Radeon 400 series is a series of graphics processors developed by AMD.These cards were the first to feature the Polaris GPUs, using the new 14 nm [8] FinFET manufacturing process, developed by Samsung Electronics and licensed to GlobalFoundries.
