"In 2019 we launched our new architecture in GPUs, it's the RDNA architecture, and that was the Navi-based products. You should expect those will be refreshed in 2020, and we will have our new next-generation RDNA architecture that will be part our 2020 lineup", said Dr. Lisa Su during the earnings call.
As detailed by the company in earlier roadmaps, the RDNA 2 architecture will be based on a 7nm+ manufacturing process, and earlier details also pointed out at variable rate shading (VRS) and ray tracing to AMD GPUs.
The variable rate shading (VRS) is a rendering technique supported by most APIs, which varies the shading rate for different parts/regions of the frame, thus increasing performance and quality. We already mentioned that AMD is playing a catch-up game with Nvidia and its GPUs, so it is not a surprise that VRS is supported on Nvidia Turing architecture, as well as Intel's Gen11 graphics architecture.
Earlier at a Q&A session after the keynote at CES 2020, AMD's Dr. Lisa Su confirmed that "big Navi" GPU is coming this year.
While talking about current 1st gen RDNA architecture Navi-based products, Su hinted that these might also get a refresh this year, but it is not clear if these are the mentioned RDNA 2 or just a refresh based on the current RDNA architecture.
In any case, AMD is hosting the 2020 AMD Investor Day conference in March, so more details will surface eventually.
