AMD reveals the summary of the new architecture Zen generation CPU "Summit Ridge" "It came back to where it can fight Intel"

In cooperation with Intel's event IDF 16 held at AMD in San Francisco, USA, AMD, a leading CPU manufacturer, will introduce next-generation microarchitecture "ZenAnnouncement of the outline. Next-generation high-end CPU code name "Summit Ridge"Reveals that the performance has reached a level to line up with Intel 's CPU.

A part of the performance of the new architecture "Zen" can be confirmed in the following presentation movie.

Zen announcement event held in San Francisco.


AMD's Lisa Suu appeared. "The new architecture has made a remarkable evolution, Zen is introduced for the first time," a press conference started.


CPU of Zen architecture will appear on AM4 platform.


Following Sue CEO, AMD's chief technology officer and senior vice president Mark Papermaster will attend. Zen is a completely newly developed microarchitecture, which means that we will be offering products from high end to low class and mobile SoC.


Zen's design philosophy is "improvement of performance", "improvement of throughput", "improvement of power saving performance".


Zen improves the number of instruction execution (IPC) per clock by 40% compared with the current CPU core "Excavator". Moreover, since the process rule has been remarkably miniaturized from 28 nm to 14 nm FinFET, power consumption reduction is realized.


Zen, who has made a significant evolution compared to the current model, has returned to the stage "(Performance Competition with rival Intel)," says Paper Master.


The Zen generation CPU is scheduled to appear from the high-end model. The high-end CPU of the code name "Summit Ridge" corresponds to DDR 4 only with 8 cores and 16 threads. It corresponds also to PCI - Express GEN 3. In addition, Intel'sHyper ThreadingAs with Zen, Zen's feature is that you can process multiple threads simultaneously with 1 core.


John Taylor, vice president of marketing for AMD, demonstrates the performance of Summit Ridge on a demonstration.


Since Summit Ridge is a CPU without GPU core, not APU, the graphic board has "Radeon RX 480"using. "Deus Ex: Mankind Divided"Was used to appeal the ability to perform FPS games easily with 4K image quality.


In the demo using "Blender" software, we compared the performance with the fifth generation Intel core processor "Broadwell-E".


Although it is slight, Summit Ridge is finishing rendering earlier. Summit Ridge appealed to Broadwell-E to be as good as the performance.


AMD is a Zen generation and aims at reviving AMD not only in CPU for consumer but also in server field. The SoC for codename "Naples" server is 32 cores 64 threads.


Thrush Golpakrynan, Vice President, Enterprise Division, presents Naples' sample motherboard. You can see that it has two Naples · SoC.


Sue CEO announced that Zen declared that there is room for further improvement in the future as products were introduced in various fields such as Consumer CPU, SoC for Server, SoC for Console, and so on.


Various presentation materials other than those introduced in the movie were released. Looking at the inside of the CPU core, the execution width / resource is increased by 1.5 times and the instruction scheduler window is increased by 1.75 times by increasing the number of operation pipes.


The cache composition has been revamped and the throughput is improving.


Simultaneous Multi-Threading technology enables simultaneous execution of 2 thread instructions per core.


14 nm FinFET process not only improves performance but also realizes substantial power saving.


In addition, "Zen +" next to "Zen" is also foretelling. We plan to further improve IPC with Zen microarchitecture.


The high end CPU "Summit Ridge" adopting the Zen microarchitecture is scheduled to appear within 2016.
