The processors of AMD Ryzen and Naples have yet to appear on the market, but almost everything is already known about their architecture. Things are worse with data on productivity: so far only the unit results of preliminary tests are in use, which, in the case of Naples, for example, frankly cannot withstand critics. However, everything will become clear with the beginning of official sales of new processors with Zen architecture. Like Intel, AMD understands that any most perfect processor architecture has its own life and without taking into account this factor you can easily be in the role of catching up. Therefore, the company published Zen Development Plane plans.
According to official figures, the source of which is the senior vice president of AMD Mark Papermaster, in the current form, the Zen architecture is designed for four years. The company is not going to adhere to the model «tick-t», Which was not so long ago even refused by Intel;Relatively speaking, AMD plans to act in style «so so so», That is, to constantly improve Zen architecture in order to increase its effectiveness both in terms of performance and in terms of energy consumption. New versions of Zen will be regularly embodied in new processors for PCs, servers and workstations. Recall that the cycle «So» In the understanding of Intel means updated architecture without the introduction of a new process. Within the framework of AMD doctrine, the next two generations Zen will be improved within the framework of the available 14-nm Finfet technology process.
The stage of use of 10-nm technology «Red» They are going to skip completely and after 2020 switch to the use of even thinner 7-nm processes. What will replace Zen? On the slides represented by AMD, the first heir to this architecture is called Zen+. It should be expected to increase the IPC indicator (performance expressed in the number of instructions executed in one beat), as well as energy efficiency. The conditional generation Zen ++ will continue the described three -stroke cycle;Unlike the Bulldozer-Sheller-Excavator chain with its transition from 32-nm to 28-nm standards of production, the change in the process is not planned. Such a strategy does not threaten AMD with a lag, since Intel will also be delayed at the stage of using 14-nm technological processes for quite some time with a series of Coffee Lake processors, the release of which should take place this year. There is also the likelihood that Intel will miss the stage of 10-nm, turning immediately to 7-nm as part of the ICE Lake and Tiger Lake projects.
The head of AMD Lisa Su confirmed that Zen architecture and its continuation will have to exist in the market for at least three years. The launch of the first generation of Zen by Intel, in the opinion of AMD, is currently nothing threatens — At least in the sector of consumer processors «Red» Obviously catch up «blue», Exposing many years of expectations of fans of the AMD brand and computer games lovers. The release of Zen+ should only fix the positions converged by the company. Already in the first generation, the Ryzen processors will receive more than 100 built -in sensors, constantly monitoring the internal parameters of the processor with an accuracy of a millivolt, millivatt and one degree and helping to provide maximum performance with minimal energy consumption. The frequency of nuclei will be adjusted dynamically with steps of 25 MHz with a frequency of up to several kHz (thousands of times per second), and the XFR technology, recognizing the enhanced cooling system, will automatically increase the upper overclocking limit for the aforementioned Precision Boost technology. Technologies «smart prediction», Neural Net Prediction and Smart Prefetch will also be improved in the process of generation Zen+, and then Zen ++;However, the third generation Zen has no official name yet.
