AMD's Eric Bergman, former CEO of Synaptics now working for AMD as Executive Vide Present, was asked in an interview about the future of Radeon graphics, including the upcoming Radeon RX 6000 series and its successor.
Unfortunately, AMD has not yet revealed too many details about the ray tracing performance of its RDNA2, based on the NAVI 21 GPU, the heart of the Radeon RX 6900 and 6800 series. Although the manufacturer has made a commitment, it will support industry standards such as the upcoming Vulkan Ray Tracing API and Microsoft DirectX Ray Tracing.
Next week, on November 18, independent tech journalists will publish the first reviews of the AMD Radeon RX 6800 series. They are known to already have working drivers, so the true ray tracing acceleration potential of the RDNA2 architecture will be revealed very soon. In case AMD itself does not disclose the details.

AMD Navi 21 GPU with Ray Accelerators
In an interview with TheStreet, Eric Bergman said that AMD's goal is 1440p resolution:
Eric Bergman: "And our goal was 1440p resolution to have a great ray tracing experience. And that was the level of performance we were aiming for. Now it depends on the specific games, all the systems and so on, but I think you'll find, that overall we have very good ray tracing performance. And gaming support will be strong throughout 2021 because we're getting that big impact again. It's just built in: you support ray tracing on Microsoft or Sony [consoles], you also support AMD. on the PC side."
Of course, this was the original (currently official) goal. It is not known whether this statement also applies to the upcoming Radeon RX 6900 XT graphics card (with full-featured Big Navi).
Also recently discussed was AMD's potential response to NVIDIA's DLSS (Deep Learning Supersampling - AI Super Resolution Scaling) technology. AMD hasn't confirmed when such technology will be available, but Bergman confirmed that it's currently called FSR (FidelityX Super Resolution) and the feature should be implemented eventually:
Eric Bergman: "We don't have a lot of details that we want to talk about. That's why we called [our solution] FSR - FidelityFX Super Resolution. But we are committed to implementing this feature, and at the moment we are working with independent software vendors. I'll just say that AMD's approach to these types of technologies is to provide broad platform support and not require proprietary solutions to be [supported by] independent software vendors. And that's our approach. So, you'll get a lot more detail in the next year. ".
AMD RDNA3
Bergman was also asked about the upcoming GPU architecture - RDNA3 - performance per watt, whether we can expect similar architectural gains when moving from RDNA2. He confirmed that AMD is equally (aggressively) committed to the following performance-per-watt improvements for RDNA3:
Eric Bergman: "Let's take a step back and talk about the benefits of both. So why are we pretty aggressively targeting the performance per watt [improvements] of our RDNA 2 [GPUs]. And then yes, we have the same commitment to RDNA 3.
[…] If you can make a significant improvement in performance per watt. On a laptop, this is of course even more obvious, since you are in a very limited space, you can simply increase the performance of this platform again without any exotic cooling solutions... We have focused on RDNA 2. This is a big focus on RDNA 3".

AMD RDNA3 architecture with Navi 3X GPUs
Another interesting part of the interview is the question about Infinity Cache on RDNA3 GPUs. Bergman believes that if RDNA2 Infinity Cache provides performance benefits, then RDNA3 Infinity Cache will definitely be considered as an option:
Eric Bergman: "We want to look forward and see what architecture will scale in the future. [With] Infinity Cache, the performance benefits, the performance per watt benefits, the cost benefits [made] a pretty easy decision to make.... I don't want to talk about our next generation [of products], but as you can imagine, once you get those benefits, they're definitely going to end up on the table for our next generation."
AMD has not confirmed the launch year for the RDNA3 series, but according to the official roadmap, the architecture should arrive by 2022. Graphics cards based on this architecture will use a new manufacturing process (AMD has not yet confirmed the plant and node). It is possible that AMD will focus on delivering the next generation "ultimate platform" including RDNA3 and Zen4 processors.
AMD will now focus on moving to the AM5 socket platform with support for DDR5 memory (and perhaps even PCIe 5.0). We don't know if this applies to the Ryzen 6000 series or if there are any possible architecture updates in the channel, but Bergman said in the same interview that such a possibility is also being considered.
