AMD Zen Microarchitecture IPC Gains Detailed

During Hot Chips AMD hosted a Zen microarchitecture presentation outlining its road to the massive 40 percent gain in IPC (Per-core performance gains), over the current Excavator microarchitecture. AMD says these gains are made possible by three major changes; a better core engine, better cache system, and lower power. Instead of using the approach they used with Bulldozer where two cores share certain number-crunching components from "modules", Zen uses a self-sufficient core design.
