Zen (family 17h) is the microarchitecture developed by AMD as a successor to both Excavator and Puma. Zen is an entirely new design, built from the ground up for optimal balance of performance and power capable of covering the entire computing spectrum from fanless notebooks to high-performance desktop computers. Zen is set to be released in early-2017. Zen is set to be eventually replaced by Zen+.
Contents
Etymology
Zen was picked by Michael Clark, AMD's senior fellow and lead architect. Zen was picked to represent the balance needed between the various competing aspects of a microprocessor - transistor allocation/die size, clock/frequency restriction, power limitations, and new instructions to implement.

Release Dates
The first set of processors, as part of the Ryzen family is expected to be officially launched before the end of Q1 - likely mid-February 2017 before the Game Developer Conference (GDC). The second batch is expected to be release toward the end of the year.
Process Technology
Zen is planned to be manufactured on Global Foundries' 14 nm process. AMD's previous microarchitectures were based on 32 and 28 nanometer processes. The jump to 14 nm is part of AMD attempt to remain competitive against Intel (Both SkyLake and Kaby Lake are also manufactured on 14 nm although by 2017 Intel plans on moving on to Cannonlake and 10 nm process). The move to 14 nm will bring along related benefits of a smaller node such as reduced heat and power consumption for identical designs.
Compatibility
Microsoft announced that only Windows 10 will have support for Zen. Linux added initial support for Zen starting with Linux Kernel 4.1.

Architecture
AMD Zen is an entirely new design from the ground up which introduces considerable amount of improvements and design changes over Excavator. Zen-based microprocessors will utilize AMD's Socket AM4 unified platform.
Key changes from Excavator
- Zen was designed to succeed BOTH Excavator (High-performance) and Puma (Low-power) covering the entire range in one architecture
- Cover the entire spectrum from fanless notebooks to high-performance desktops
- More aggressive clock gating with multi-level regions
- Power focus from design, employs low-power design methodologies
- Utilizes 14 nm process (from 28 nm)
- 40% improvement in IPC per core per single-thread (From Excavator)
- Core engine
- SMT support, 2 threads/core
- Improved branch mispredictions
- Better branch predicitons with 2 branches per BTB entry
- Lower miss latency penalty
- Large Op cache
- Wider μop dispatch (6, up from 4)
- Larger instruction scheduler
- Larger integer physical RF (84, up form 48)
- Larger FP physical RF (96, up form 60)
- Larger retire throughput (8, up from 4)
- Larger Retire Queue (192, up from 128)
- Larger Load Queue (72, up from 44)
- Larger Store Queue (44, up from 32)
- Quad-issue FPU
- Cache system
- Write-back L1 cache eviction policy (From write-through)
- Faster L2 cache
- Faster L3 cache
- Large Op cache
- Faster Load to FPU (down to 7, from 9 cycles)
- Better L1$ and L2$ data prefetcher
- 2x the L1 and L2 bandwidth
- 5x L3 bandwidth
- Move elimination block added
