The slides confirm Zen offers a new core design with support for simultaneous multithreading (SMT), which is somewhat similar to Intel's HyperThreading. Zen has a new high-bandwidth low-latency cache system and will be made on a 14nm FinFET process.
It will be interesting to see if AMD can keep its promise this time. A 40 percent higher IPC combined with higher frequencies could deliver a pretty big boost in performance versus the current generation, but the availability of these chips is still quite some time away from us. The slide also mentions plans for Zen+ cores after 2016 with more modest increases in IPC efficiency.
The Zen-based FX-series (which seems to lack integrated graphics) and the 7th generation A-series desktop APUs will share the same platform, which will be the new Socket AM4. In the laptop market, AMD will offers its 7th gen A-series mobile APUs, these will use the FP4 socket.
