AMD showed a prototype Ryzen 3000 on the architecture of Zen 2: eight cores and +15% performance
During the event at CES 2019, AMD publicly demonstrated for the first time your prospective processor Ryzen third generation, based on the microarchitecture Zen 2 and produced for 7-nm technology. The demonstration was of a preliminary nature, the characteristics of future products was not announced, however, the Executive Director of AMD, Lisa su (Dr. Lisa Su), promised that the novelty will be officially presented in mid-year.

However, it was confirmed that future CPU’s from AMD for desktops will be collected from multiple crystals of different types of chipsetov. One of the crystals is performed on a 7-nm technology chipset with eight processor cores, Zen 2, the production of which will be answered by the company TSMC. Second chiplet — produced by 14-nm technology at GlobalFoundries enterprises crystal with a memory controller, bus controller and other PCI Express systems. It follows from the comments of the head of AMD, obtained by journalists after the event, the company does not deny the possibility of producing desktop processors with more than one chiplet with cores.
While AMD had the right to promise Ryzen third generation will be the first processors for the mass users, released on 7-nm technology, and the first processors with the implementation of PCI Express 4.0. However, it is clear that to support the new version of tyres will need a new motherboard. In the old motherboards work with which certainly will be saved, the PCI Express bus, apparently, will work in a usual mode 3.0.
During the demonstration the audience was given sample Ryzen third generation processor without a lid, allowing to verify its double-crystal design. Judging by the size of the crystals, the processor uses the same chipley with cores that used in future EPYC (generation Rome), but “peripheral” chipset in this case is different.
AMD also showed a workable system on the basis of the future CPU Ryzen with a new Radeon VII. In testing the popular benchmark Cinebench R15 computer and shestnadcatiletnim promising OCTA core processor scored 2057 points. This is approximately 15 % more than in the same test shows the eldest of the current generation Ryzen, Ryzen 7 2700X. However, it should be borne in mind that AMD has not yet been named target clock frequencies of their future products and the pre sample which was installed in the test system, must have worked at frequencies far from final. In other words, the future eight-core Ryzen three series have a chance to be significantly faster at rendering than Core i9-9900K, which in Cinebench R15 is in the area of 2040 points.
Besides already promising Ryzen was able to impress with their characteristics of energy consumption. The system is based on it during the performance test Cinebench R15 consumes only 130 watts, while the consumption of working close system with a Core i9-9900K, under a similar load reached 180 watts.
It is worth mentioning that the Zen design 2 in addition to the transition to new manufacturing process promises and visible micro-improvements. The new processors will be improved branch predictions, and prefetching of instructions, optimized performance and increased cache micro-operations, improved the capacity of Manager teams, implemented a “fair” support for 256-bit floating point operations, as well as faster loading and saving data.
In addition, chipley the latter does not put an end to the possibility of an increase in Matisse cores. AMD theoretically has the ability to add inside the processor packaging another chipset with eight cores, and thus obtain the 16-core desktop processor. After his speech Lisa su in a private conversation hinted at this possibility: “If you look at the evolution of Ryzen, we have always had the advantage in number of cores”, — she told reporters of PCWorld. And then with a grin added: “Some might notice in the package for more space, and I think we can expect that we will have more than eight cores”.
More information about future chips from AMD promises to provide closer to the announcement.
