RDNA 3 is a GPU microarchitecture designed by AMD, released with the Radeon RX 7000 series on December 13, 2022. Alongside powering the RX 7000 series, RDNA 3 is also featured in the SoCs designed by AMD for the Asus ROG Ally , Lenovo Legion Go , and the PlayStation 5 Pro consoles.
RDNA 3 (also RDNA3) is the successor to the RDNA 2 microarchitecture and was projected for a launch in Q4 2022 per AMD's gaming GPU roadmap. [ 46 ] [ 47 ] [ 48 ] At an August 29 reveal event for Ryzen 7000 series CPUs, AMD CEO Lisa Su teased RDNA 3 and revealed that it would utilize chiplets built on TSMC 's N5 node. [ 49 ]
The Radeon RX 7000 series is a series of graphics processing units developed by AMD, based on their RDNA 3 architecture. It was announced on November 3, 2022 [1] and is the successor to the Radeon RX 6000 series. The first two graphics cards of the family (RX 7900 XT and RX 7900 XTX) were released on Dec 13, 2022.
As a result, Lovelace GPUs would be limited by DisplayPort 1.4a's supported refresh rates despite the GPU's performance being able to reach higher frame rates. Intel's Arc GPUs that also released in October 2022 included DisplayPort 2.0. AMD's competing RDNA 3 architecture released just two months after Lovelace included DisplayPort 2.1. [23]
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.

RDNA 2 is a GPU microarchitecture designed by AMD, released with the Radeon RX 6000 series on November 18, 2020. Alongside powering the RX 6000 series, RDNA 2 is also featured in the SoCs designed by AMD for the PlayStation 5 , Xbox Series X/S , and Steam Deck consoles.
VCN 3.0 is implemented with Navi 2 products. [5] VCN 3.0 implements H.264 B-frames, which was present in Video Coding Engine 2.0 but taken out with VCE 3.0. [6] VCN 4.0 adds AV1 encode. [7] H.264 quality is higher with VCN 4.0 (as part of RDNA 3) compared to previous generations, but still lags behind Intel and Nvidia hardware codecs. [8]
