The 7nm Ryzen 3000 series is expected to be launched at Computex late next month and AMD is also going to talk about Navi. However, it's still unknown whether Navi will launch in tandem with the Ryzen 3000 series:
But there’s yet to be any mention of AMD Navi from any of the official channels, and we haven’t been entirely convinced AMD will manage to launch AMD Navi concurrently with its latest CPUs. It would be a bold move, that’s for sure, and one that would get the hype train moving full steam ahead, but it could also put considerable pressure on TSMC to manufacture a hefty volume of both in the preceding months.
