History
Zen 3 was formally disclosed in a roadmap by Lisa Su, AMD's CEO, during AMD's Tech Day in February of 2017. Zen 3 will be the 3rd iteration of the Zen microarchitecture. On Investor's Day in May 2017 Jim Anderson, AMD Senior Vice President, confirmed that Zen 3 is set to utilize 7nm+ process.

Process technology
Zen 3 will be fabricated on TSMC's 7nm+ process.
Architecture
There is very limited information available about the architectural improvements of Zen 3.
Key changes from Zen 2
- Unified 8-core CCX with 32 MiB L3$ available to all 8 cores equally
- Wider and more flexible issue in floating-point and integer engines
- Increased number of loads and stores, improved prefetching
- Increased branch prediction bandwidth, "zero-bubble" branch prediction
- Improved µop cache
- [Unconfirmed] 7 nm+ process (from 7 nm), 20% more density and 10% power reduction compared to Zen 2. EUV (Extreme Ultraviolet) lithography 7nm+.
This list is incomplete; you can help by expanding it.
