AMD were light on concrete details surrounding the RDNA 4 architecture or the Radeon RX 9000 series during their CES keynote. [5] The Radeon RX 9000 series targets midrange performance and value rather than competing with Nvidia at the high-end like the Radeon RX 7000 series did. [6] This is a similar approach taken by the RX 5000 series in 2019.
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.
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 ...
The R300 GPU, introduced in August 2002 and developed by ATI Technologies, is its third generation of GPU used in Radeon graphics cards.This GPU features 3D acceleration based upon Direct3D 9.0 and OpenGL 2.0, a major improvement in features and performance compared to the preceding R200 design.
Architecture – The microarchitecture used by the GPU. Fab – Fabrication process. Average feature size of components of the GPU. Transistors – Number of transistors on the die. Die size – Physical surface area of the die. Core config – The layout of the graphics pipeline, in terms of functional units.
TeraScale is a VLIW SIMD architecture, while Tesla is a RISC SIMD architecture, similar to TeraScale's successor Graphics Core Next. TeraScale implements HyperZ. [3] An LLVM code generator (i.e. a compiler back-end) is available for TeraScale, [4] but it seems to be missing in LLVM's matrix. [5] E.g. Mesa 3D makes use of it.
As of July 2017, the Graphics Core Next instruction set has seen five iterations. The differences between the first four generations are rather minimal, but the fifth-generation GCN architecture features heavily modified stream processors to improve performance and support the simultaneous processing of two lower-precision numbers in place of a single higher-precision number.
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] The benefit of using chiplets is that dies can be fabricated on different process nodes depending on their functions and intended purpose.
