AMD Says RDNA3 50% Perf/Watt increase and mentions RDNA4

AMD said that the next RDNA3 graphics architecture will deliver a generational performance/Watt gain of more than 50%.

AMD has stated that RDNA 3, similar to Zen 4, would be made using a 5nm technology, with additional compute units and a reworked rendering pipeline. A new iteration of the fast Infinity Cache is also believed to have been introduced. RDNA4 was not mentioned, save that it will be created on a more advanced node than 5 nm. RDNA3 will be introduced on the TSMC N5 (5 nm) silicon production node, with a chiplet-based architecture similar to what AMD did with its 2nd Generation EPYC Rome and 3rd Generation Ryzen Matisse CPUs.

Memory controllers, display controllers, media engines, and other I/O components will be housed on a separate die. The GPU's fundamental number-crunching and 3D rendering circuitry will be housed on chiplets, while I/O components like as memory controllers, display controllers, and so on will be housed on a separate die. 

AMD also reveals AV1 encoding capabilities and DisplayPort 2.0 compatibility as additional RDNA 3 architectural characteristics on the audio track.

The compute units have been rearchitected using RDNA3 to improve their IPC. RDNA3 will also be paired with next-generation Infinity Cache on-die cache memory technology. AMD RDNA3 is expected to be released in the second half of 2022, with a progressive increase until 2023.  The successor to the RDNA 3 architecture should emerge in 2024 with Navi-4x GPUs based on RDNA 4, however, AMD has said nothing about it.
