After yesterday's grand unveiling of its 3D V-Cache Stack Chiplet Design, AMD has confirmed that the technology will be introduced in its Zen 3 powered Ryzen CPUs coming early next year.

AMD did a great job explaining the technology but didn't acknowledge which Zen CPUs were going to be the first to feature it. Their demonstration included a Zen 3 based Ryzen 9 5900X prototype & the company has now confirmed that the 3D V-Cache Chip Stacking technology is indeed coming to Zen 3 CPUs first.
