According to the announcement, the webinar will include "a sneak peek at socket AM5 B650E and B650 motherboards, as well as lineup, specifications, and features from the aforementioned partners. AMD promise to show "how the socket AM5 platform and AMD Ryzen 7000 series processors deliver incredible performance".
AMD is officially launching the Ryzen 7000 CPUs and X670E/X670 motherboards on September 27th, and we expect the B650 series motherboards to come to retail/e-tail in mid-to-late October.
This is a welcomed announcement considering the recent leaks for X670/X670E pricing.
