AMD is expecting the next-gen RDNA 3 GPUs scheduled for 2021 to deliver 50% improved performance-per-watt over the new RX 6000 series

We have not even got a chance to explore the limits of the new RX 6000 GPUs based on the RDNA 2 architecture, and AMD is already planning some impressive performance gains for the upcoming RDNA 3 cards that should release in late 2021. The performance uplift should be facilitated through MCM structures and the jump to 5 nm.

In an interview with online publication The Street, AMD’s Executive Vice President Rick Bergman provided some interesting facts about the upcoming RDNA 3 GPU architecture and the Zen 4 CPU architecture. It is interesting to see AMD already planning ahead for the next iterations when we have barely seen what the new Zen 3 CPUS and RDNA 2 GPUs are capable of. This could further prove that AMD is looking to commit to releasing substantially improved versions on a yearly basis.

When asked about the benefits of the RDNA 3 architecture over the RDNA 2 one currently powering the new Radeon RX 6800 / XT and RX 6900 XT GPUs, Bergman quickly pointed out that the performance-per-watt gains should be similar to the improvements achieved with the leap from RDNA 1 to RDNA 2. “... We have the same commitment on RDNA 3… We focused on that on RDNA 2. It's a big focus on RDNA 3 as well.” Bergman notes that the key here is to maintain a similar TGP while delivering 50% more performance so potential users are not forced to buy bigger power supplies and replace the cooling solutions like with Nvidia's RTX 3000 cards. We are still not sure if this will be facilitated through the use of the advanced TSMC 5 nm nodes. From what we heard in previous rumors, it looks like both RDNA 3 and Zen 4 should use the 5 nm nodes, and Bergman seems to indirectly confirm this as he is corroborating the RDNA 3 performance gains with the expected Zen 4 gains. We are also hearing that the RDNA 3 GPUs will adopt a multi-chip module (MCM) approach.

Bergman also explained that the top-of-the-line RDNA 2 GPUs are designed to provide a smooth ray traced experience at 1440p resolutions. Additionally, AMD’s answer to Nvidia’s DLSS will come in the form of FSR (FidelityFX Super Resolution) but there is no exact time frame for its arrival. In this respect, Bergman stated that AMD is “committed to getting that feature implemented, and we're working with ISVs (independent software vendors) at this point. I’ll just say AMD’s approach on these types of technologies is to make sure we have broad platform support, and not require proprietary solutions from the ISVs. And that's the approach that we're taking. So as we go through next year, you'll get a lot more details on it.”

I first stepped into the wondrous IT&C world when I was around seven years old. I was instantly fascinated by computerized graphics, whether they were from games or 3D applications like 3D Max. I'm also an avid reader of science fiction, an astrophysics aficionado, and a crypto geek. I started writing PC-related articles for Softpedia and a few blogs back in 2006. I joined the Notebookcheck team in the summer of 2017 and am currently a senior tech writer mostly covering processor, GPU, and laptop news.
