Last night, AMD held another event at the CES 2019 exhibition, where it introduced the new seven-grain Ryzen 3000 processor to the world (Zen 2) and a new video card with a Vega II, a semi-dollar GPU. The latter is called the Radeon VII, which is a bit strange, but perhaps it is a reference to the code name of the graphics core. Probably, with the release of the next generation Navi, the “reds” will change the approach to designating their video cards.
Let's start with the video card. It is based on the 7-nm Vega II graphics processor, supplemented by 16 GB of HBM2 multi-layer memory with a throughput of 1 TB / s. If we talk about the specifications, then AMD has not disclosed them. The graphics accelerator is known to operate 60 CU computing units with 3,840 stream processors operating at about 1.8 GHz.
The company reports a raw performance of 13.8 TFLOPS and a 25% average performance increase compared to Vega 64 with the same energy consumption. That is, despite the semi-process technology, the TDP of the video card will be rather big. Actually, the reference version of the card requires the connection of two eight-pin power connectors and is equipped with a massive cooling system with three fans.
According to AMD, in games the new product demonstrates 25-42% better performance than Radeon RX Vega 64, which was published a year and a half ago. During the presentation, the representatives launched the not yet released Devil May Cry 5 in 4K with the maximum graphics settings during a presentation to demonstrate the capabilities of the Radeon VII. During the test, the FPS counter showed from 70 to 120 fps.
AMD Radeon VII will go on sale on February 7 with the recommended price of $ 699. That is, AMD Radeon VII will compete with the current flagship video card "green" NVIDIA RTX 2080, which is offered for the same $ 700 (non-reference version). It remains to add that the AMD Radeon VII will be accompanied by digital copies of Resident Evil 2, Devil May Cry 5, and Tom Clancy’s The Division games. We can only wait for the independent tests and see how formidable the rival AMD Radeon VII will be for NVIDIA RTX 2080.
Turning to the processors, we immediately note that this announcement is purely nominal. The output of the Ryzen 3000 series chips (Zen 2) is scheduled for the middle of this year. That is, a full-fledged announcement with all the details, a list of models and prices will be held at Computex 2019, which will be held from May 28 to June 1 in Taipei.
As part of the presentation, AMD showed engineering chips samples. They are based on Zen 2 microarchitecture and use Chiplet multi-chip layout, which AMD told about last year. Recall that the same multi-modular design is used in AMD EPYC server processors of the 2nd generation.
As can be seen in the photo, the processor includes two crystals adjacent to a common substrate. In this case, this is a 7-nm computational module containing 8 cores on the Zen 2 architecture, and a 14-nm chip containing the set of necessary controllers and interfaces, that is, in fact, a set of logic. To connect the crystals together, use the interface Infinity Fabric. The new Ryzen CPUs will be the first in the market to get support for the PCIe 4.0 interface, but we learned about this in November. Separately, it is worth noting that the third generation Ryzen processors will be compatible with existing AM4 platforms. That is, to upgrade will not necessarily buy a new motherboard.
For a visual demonstration of the possibilities used Forza Horizon racing game. With it, a test system with an unknown new CPU Ryzen and a Radeon VII video card handled without problems, yielding over 110 fps in 4K with maximum graphics settings. In the synthetic test Cinebench R15, the early model of the new Ryzen CPU showed a result at the level of Core i9-9900K with standard frequencies with a lower level of power consumption (133 W vs. 180 W). It is reported that an early sample processor AMD Zen 2 during the test ran at 4.6 GHz. Probably, the frequency of the consumer version will be higher.
