WCCF Tech writes next year's Navi launch will be the 6th generation GCN, thereby marking the final microarchitecture of the GCN branch.
Work on this post-GCN architecture started under the reign of Raja Koduri but development reportedly accelerated once he left. The new design will be spearheaded by David Wang and Mike Rayfield.
AMD has already hinted in its slide deck about the existence of this major architecture. Remember the “Next-Gen” micro-architecture that was listed in their roadmap? Well, its the one and the same. We don’t know a lot of details about it at this point apart from the fact that it will be based on the 7nm+ process and will succeed GCN sometime in 2020/2021. If all goes as planned, Navi will be the last iteration of GCN macro architecture that hits the market.The site heard the new architecture aims to provide a big leap in terms of performance, similar to what we saw when AMD moved from TeraScale to GCN.
