A new feature AMD has added to the 400-series chipset is "{{amd|StoreMI}}", a technology with very similar capabilities to Intel's {{intel|Smart Response Technology}} which attempts to combine the benefits of fast, but expensive, [[solid-state drive|SSDs]] along with cheap high-capacity, but slow, [[hard disk drive|HDDs]]. StoreMI combines the two storage devices into a single virtual drive (single letter drive on {{microsoft|Windows}}) and automatically manages and moves the data across the drives. Essentially, the chipset uses the SSD as a cache for traditional hard drives. The idea is to keep the most recent and most accessed data on the SSD in order to improve real-world responsiveness while keeping the less used data in the slower mechanical hard disk in order to preserve the capacity of the SSD. It’s worth noting that this hierarchy of secondary storage devices can actually extend to main memory. Up to 2 GiB of RAM may be configured and reserved as another level of cache for the HDD on top of the SSD.

Succession

Zen+ (Zen Plus) is the successor to Zen, a 12 nm microarchitecture designed by AMD and introduced in 2018 for the mainstream PC, enthusiast, and server markets. Zen+ was succeeded by Zen 2 in 2019.

Zen+ based processors are sold under the brand 2nd-Generation Ryzen and 2nd-Generation Threadripper.

History[edit]

Zen+ Roadmap

Zen+ succeeded Zen in April of 2018. Zen+ features the same core as Zen but takes advantage of the new GlobalFoundries' 12nm process to deliver higher clock speeds and improved power consumption. Zen+ was initially mentioned by AMD's senior fellow and lead architect of Zen, Michael Clark, during Hot Chips 28 in 2016 as part of AMD's continuing commitment in the high-performance computing market.

Codenames[edit]

Core C/T Target
Colfax Up to 32/64 Enthusiasts market processors
Pinnacle Ridge Up to 8/16 Mainstream to high-end desktops & enthusiasts market processors
Picasso From 2/4 to 4/8 Mainstream desktop & mobile processors with GPU

Process Technology[edit]

See also: 12 nm process

Zen+ is manufactured on Global Foundries' 12 nm process Leading-Performance (12LP), an enhanced version of their 14nm process. The enhanced process provides up to 15% higher density or up to 10% higher performance. 12LP brings around a 10% frequency bump for the Ryzen lineup at the same power envelopes.

Note that AMD did not switch to standard libraries and instead chose to get whatever added performance they could get from the same physical design as 14 nm. This also means some performance was left on the table and the die size is exactly the same as Zen.

Compatibility[edit]

Linux added initial support for Zen starting with Linux Kernel 4.10. Microsoft officially only supports Zen on Windows 10. Windows 7 and 8 drivers are available for many mainboards. But drivers must be integrated into the installation image or installed first before switching to a Zen-based system. Otherwise support for any kind of USB device like keyboard and mouse would be missing.

Vendor OS Version Notes
Microsoft Windows Windows 7 No Support
Windows 8 No Support
Windows 10 Support
Linux Linux Kernel 4.10 Initial Support

Compiler support[edit]

Zen+ is largely the same architecture as Zen and thus uses the same compiler switches.

AOCC ‐march=znver1 -mtune=znver1

Pipeline[edit]

Zen+ pipeline is identical to Zen's.

Memory Subsystem[edit]

When AMD presented their paper at ISSCC 2018, WikiChip was able to confirm with AMD's SoC architect that Zen's L2 latency was always designed to be 12 cycles. In fact all Zen-based microprocessors (including EPYC, Ryzen Threadripper, and Zen-based APUs) have an L2 latency of 12 cycles for all access patterns. Only mainstream Zen-based Ryzen processors (i.e., Summit Ridge) have a latency of 17 cycles. The problem has been sorted out with Zen+.

Sockets/Platform[edit]

All Zen+-based mainstream consumer microprocessors utilizes AMD's Socket AM4, a unified socket infrastructure. All those processors are a complete system on a chip integrating the northbridge (memory controller) and the southbridge including 16 PCIe lanes for the GPU, 4 PCIe lanes for the NVMe/SATA controllers as well as USB 3.0. The chipset, however, extends the processor with a number of additional connections beyond that offered by the SoC.

StoreMI[edit]

A new feature AMD has added to the 400-series chipset is "StoreMI", a technology with very similar capabilities to Intel's Smart Response Technology which attempts to combine the benefits of fast, but expensive, SSDs along with cheap high-capacity, but slow, HDDs. StoreMI combines the two storage devices into a single virtual drive (single letter drive on Windows) and automatically manages and moves the data across the drives. Essentially, the chipset uses the SSD as a cache for traditional hard drives. The idea is to keep the most recent and most accessed data on the SSD in order to improve real-world responsiveness while keeping the less used data in the slower mechanical hard disk in order to preserve the capacity of the SSD. It’s worth noting that this hierarchy of secondary storage devices can actually extend to main memory. Up to 2 GiB of RAM may be configured and reserved as another level of cache for the HDD on top of the SSD.
