The amd zen 5 architecture is under development and would use a 5nm node
Table of contents:
AMD has just released its 7nm-based Zen 2 architecture, but it appears that post-2020 core development is already underway. Although we know Zen 3 and Zen 4, it seems that their Zen 5 architecture is already planned and up and running, which more or less confirms it for future generations of Ryzen, Threadripper and EPYC processors.
Zen 5 architecture would use a 5nm node
AMD's Zen 5 will be a post-2021 architecture that will be featured on future-generation processors in the Ryzen family, Threadripper, and EPYC. We can't confirm whether AMD will use the same CPU naming conventions in 2020 and beyond, but just like now, all processor families will feature the new Zen architecture.
The AMD Zen 5 core was confirmed by AMD some time ago in its slides during the launch of Zen +. This has been confirmed once again by David Suggs, who is the chief architect for the AMD Zen 2 and Zen 5 microprocessor cores. AMD has teams within the CPU department that are working on different Zen cores in parallel. David, in particular, has been the chief architect behind the AMD Zen 2 core who recently made his debut with Ryzen 3000 processors and also with upcoming Zen 5 cores.
We know that AMD's Zen 2 is based on the 7nm architecture and the next Zen 3 would be based on the 7nm + process as early as 202. The AMD Zen 4 cores are currently under design and scheduled for release in 2021. By then, AMD is expected to jump to the 5nm process node, allowing processor cores to be up to 80% denser than 7nm currently allows.
If AMD were to use TSMC's latest 5nm node, also known as N5, the company could expect an 80% increase in transistor density, 15% in overall performance, and a 45% reduction in array area with its next-generation Zen-based Ryzen series.
With this 'roadmap', it is easy to anticipate that the Zen 5 core should be released between 2022 and 2023 with an optimized node of 5nm, which would allow to increase performance significantly.
Upcoming nvidia gpus would use samsung's 7nm euv node
Recent reports are suggesting that future Nvidia GPUs would be developed with a Samsung 7nm EUV node.
Navi would continue to use the gcn graphic architecture
AMD has begun to introduce the first hints of its Navi graphics into its open source Radeon controllers. I would still use GCN.
Zen 4, amd would launch the first cpus in 2021 with a 5nm node
Zen 4 processors slated for 2021 are going to take advantage of this new processing node and probably Radeon Navi GPUs.
