In talking about the new hardware, AMD client business unit SVP Saeid Moshkelani said:

With the launch of AMD Ryzen PRO 4000 Series Mobile Processors, AMD once again defines the new standard for PC experiences – from high-end desktop computing to ultrathin and gaming notebooks, and now the modern business notebook. Built on the ground-breaking 'Zen 2' architecture and 7nm process technology, the AMD Ryzen for Business portfolio delivers advanced performance, reliable security features, impressive battery life and advanced manageability to significantly elevate the capabilities of the ultrathin notebook in any work environment.

In a separate announcement, AMD talked about the future of its Socket AM4; the company previously said that it would support it until 2020. Now that 2020 has arrived, the company says that its Zen 3 architecture will be compatible with the Socket AM4, but that Zen 3 architecture support will not be offered for older chipsets. The company doesn't have any info to announce about a new socket at this time, nor any roadmaps to share, explaining that how long the Socket AM4 lasts will depend on the wider industry.
