Together with its Q1 2019 financial results, AMD shared an update about what's in store for the rest of the year. CEO Lisa Su revealed both the 7nm Navi GPU and the "Rome" EPYC server processors are slated for a Q3 2019 launch.
During the earnings call with financial analysts, Su added that Navi is a new architecture with a lot of new features. She refused to go in detail about whether it supports ray tracing, or other features, but clarified that Navi will be positioned below where the Radeon VII is positioned today.
This confirms what we've been hearing for quite some time now, that Navi is a mainstream GPU architecture and not a new high-end product. It's basically the successor to the Polaris series.
