After releasing their high-end Radeon VII in February 2019, AMD is now directing its attention to the middle segment with its graphics cards AMD Navi of 7 nanometers (nm). The new product plays with the power of AMD: the graphics power of high end is more affordable than ever.Although it is expected that the AMD Navi play an important role in the console PlayStation 5 Sony, which can cause problems with the supply of the chips, the latest rumors suggest that it could reach out to consumers in mid-summer of 2019. When you do, it will compete seriously with the graphics cards, entry-level series RTX and GTX 16 Nvidia.
Pricing and availability
The portal Network Gaming Tech reported in January that the new AMD cards Navi would come in July 2019, at the Electronic Entertainment Expo (E3). After the launch of the Radeon VII in February, the portal stated that AMD was planning to the presentation of the Navi to the 7 of July, in addition to the processors Ryzen 3000 and the motherboard x570.
And despite the fact that in another version suggested that it might be delayed -some spoke of October-, not to repeat the problems of stock of the Radeon VII, the latest report suggests that not only will be presented at E3, but that would be officially released.
Anyway, it is likely that AMD has two variants. The initial reports suggested that the GPU Navi 10, and Navi 11 would be the first, but is now believed to be Navi 12, and Navi 10.
While gamers will have to wait until 2020 for a graphics card Navi 20 high-end, it is rumored that the first will have a price between $130 dollars and $250 dollars. If so, will face GTX 1660 Ti and the GTX 1060 of the latest generation, surpassing in more than $100 dollars to the new RTX 2060. The estimates are in line with the position of Navi as a successor to Polaris. The cards of the Radeon series RX 500 AMD usually vary between $115 and $290 dollars.
The rumors also suggested that AMD could play a psychological advantage in the nomenclatures. As called 400-series to its processors Ryzen (one more digit than the 300 series from Intel), you could call RX-series 3000 on their cards, Navi, making them seem more modern than 2000 Nvidia.
Architecture and performance
AMD has not given any information about the performance potential of Navi. But if you offer an improvement of 30% on the Polaris, as it did with the Radeon VII architecture 7 nm, it would be a huge boost. In leaks of internal testing, Fudzilla said that the performance of Navi had surpassed the expectations of AMD, and that would even offer the best performance at midrange prices.
Although initially it was speculated that for about $250 would provide a performance as the card Vega 56, is then compared with the RTX 2070 at the same cost. The high end solution, to be called the 3080, you would have 8 GB of GDDR6, and 15 per cent more power than the Vega 64 with TDP (Thermal Design Power) of only 150 watts. The 3070 would be closer to a Vega 56 with 120 watts, while the 3060 would have a similar performance to the RX 580 with 75 watts.
The numbers of the AMD Navi seem to be extremely optimistic, especially because they are offering a performance close to the recently launched Radeon VII, but cut enormously your price of $700 dollars.
Preliminary transpired that the AMD Navi would be the last GPU from the manufacturer based on the architecture graphics core (GCN). Now, however, it is speculated to debut with a new microarchitecture, overcoming limitations of GCN. This implies that you would have faster clock speeds and greater efficiency. AMD confirmed that Navi will have scalable architecture that will support memory HBM2 and GDDR6. According to PC World, will not be a focus of the module chip multiple.
In April of 2019, Mark Cerny, the chief architect of Sony PlayStation, has confirmed that the next generation of consoles would have nuclei Navi custom, and the processor Ryzen 3000, based on its architecture Zen 2. It is not clear if this will be a design of an Accelerated Processing Unit (APU, for its acronym in English), or custom if you would be a graphics card Navi dedicated. The PS4 and the PS4 Pro used a design of the APU, but considering the scalability of the Navi, perhaps, be separated to allow for future expansions.
Shading and variable rate
The dramatic increase in the resolutions of monitors in the last few years, with the screens and 4K becoming more common and even some 8K on the road, has meant an overload for the graphics cards. Even for the most powerful, you run a high resolution, it is a strenuous work. Here is where I come to play technologies as the shading rate variable (VRS).
The RSV renders portions of a screen with a greater fidelity. In theory, you could use the gestures of the player (taking advantage of the eye-tracking) or just concentrate on the center of the screen. Is a more efficient way of rendering frames that do not affect the visual quality.
Even if AMD had not confirmed the support of VRS with Navi, a patent filed by AMD in August of 2017 and published at the end of February 2019, they discussed the implementation of this technology with graphics hardware. Considering the time of submission and approval, integration with Navi it would make sense.
With the architecture graph of Navi mumbai which may drive the next generation of consoles from Microsoft and Sony, it is possible to VRS finished helping those systems improve the images of the games beyond what consoles can do. It would also prolong the life of these consoles.
However, this claim was questioned after it was revealed that the next generation of PlayStation will have an AMD graphics card Navi custom and admit the ray tracing. That suggests that Navi has the graphics power to support ray tracing in games, but the question remains how it will be done.
The first rumors suggested that it would be a unique feature of the Navi 20 high-end. However, it is likely that the PS5 will not use a graphics chip so expensive and high-end, so that the navigation device 10 might also support the ray tracing. That would support the claims of AMD that I would want to do that ray tracing was widely available, when implemented in the Radeon graphics cards.
AMD could implement ray tracing in Navi 20 for the PC and the chip Navi custom consoles, both in 2020, leaving the release of Navi 10 in 2019 as an introduction to the platform.
In the CES 2019, the CEO of AMD, Lisa Su, said that the technology of ray tracing was “development in depth”. She even announced that the Radeon VII will support a technology similar to that of the DLSS of Nvidia. It is not clear if Navi will take advantage of something similar to overcome the performance problems associated with ray tracing. However, to keep prices competitive, it is unlikely that the architecture of the GPU come with cores ray tracing dedicated.
