Rumour Mill: AMD Navi 20-GPUs to Support Ray-Tracing?
Update 2: AMD Navi 20-GPUs to Support Ray-Tracing?
While the first generation of AMD’s Navi-based GPUs haven’t even arrived yet, the Texas-based chip manufacturer is already hard at work on ist successor: Navi 20. The graphics cards based on Navi 10 will utilise the 7 nm process node and the flagship of this series will appear in the form of the Radeon RX 3080. Previous rumours indicated that the Radeon RX 3000 series would be aimed at the mid-range segment. Navi 20-based graphics cards on the other hand would therefore make more sense as members of AMD’s high-end line up. wccftech.com (external link) has a video from RedGamingTech (external link) to discuss the rumours swirling around Navi 20 at length.
These rumours are, as always, best taken with a pinch of salt. Navi 20 GPUs are reported to offer an improved GCN architecture that also supports ray-tracing. In addition to ray-tracing support, AMD graphics cards with a Navi 20 graphics chip should offer a huge leap forward in terms of performance – perhaps even more so than the top models of competitors. One of the reasons behind the improvement in performance with Navi GPU architecture has can be traced back to the influence of Raja Koduri. It was his leadership that fostered a wealth of optimisations regarding GCN’s architecture prior to his departure to Intel. Koduri had a long and illustrious history stretching back to 2009 at AMD, prior to which he spent four years at Apple. From 2013 to 2017, Koduri worked once more for AMD and in 2015 became Senior Vice President and Chief Architect of AMD’s Radeon Technology Group.
The levels of performance on offer from Navi 20 GPUs certainly seems to have a lot to do with Koduri’s long-term leadership, and we can see this manifest once more in Intel’s work on producing a dedicated graphics card of their very own. Relatively little is currently known about the Navi graphics chip, and the same goes for performance as things currently stand. One thing that is confirmed is that ray-tracing will not require specialist cores, as is the case with Turing. Whether AMD already has such cores in development or plans to achieve similar performance by means of traditional Shader Units remains unclear. Further news and rumours on Navi 10, Navi 20, the Radeon RX 3080 and the Radeon 3000- series will be added to the blog in the near future.
Update 1: AMD Navi Radeon RX 3000 GPU Benchmarks Leaked?
Rumours regarding the Radeon RX 3080 and whether it will its place at the top of AMD’s high-performance aside, another benchmark leak of a different Radeon graphics card has recently appeared. Courtesy of wccftech, (external link) benchmarks of a Navi-based GPU (“Radeon RX 66AF: F1”) have appeared that show that, even with just 1280 Shaders, it manages to produce more performance than a Radeon RX 580 with 2304. Of course, please take such benchmarks with the requisite pinch of salt, especially since the rumoured number of Shaders seems to have been deduced from the number of Compute Units (CUs). Should the Navi GPU architecture of the RX 3080 and the smaller Navi-based GPUs be revised from the ground up, the final Shader count could of course be higher. In spite of all this, the performance increase is impressive to say the least – especially given that some benchmarks show more than a doubling in performance when compared to its Polaris predecessor!
Original Post: AMD Radeon RX 3080 – The New High-End Graphics Card?
The internet has been ablaze with rumours over the past few days about new graphics cards from AMD. The Texas-based chip manufacturer may be gearing up to present the Radeon RX 3080 based on the new Navi GPU architecture. The RX 3080 and other gaming graphics cards from AMD that use Navi will apparently be manufactured in a 7nm node. This combination of new architecture and a node shrink could well result in some drastic performance improvements – all with a low TDP.
In our blog about AMD’s new hardware at CES we collected together some of the first publicly available information on the Radeon RX 3080. As the top model of the RX 3000- series, the Radeon RX 3080 will be based on Navi 10 and supposedly provide 8 GB of GDDR6 VRAM. Thanks to a wide array of optimisations and a node shrink, performance and efficiency should both undergo marked improvements compared to the previous generation. The Radeon RX 3080 has been rumoured to offer approximately 15 percent greater performance over that of the RX Vega 64.
The Radeon RX 3080 was originally supposed to offer performance comparable to the NVIDIA GeForce RTX 2070. wccftech.com (external link) is drawing on a trusted source who asserts that the RX 3080 will offer performance that is comparable to the GeForce RTX 2080. However, the Navi architecture is highly unlikely to support ray-tracing technology to an extent similar to that of NVIDIA’s series of high-end graphics cards.
If the Radeon RX 3080 is presented at CES 2019 in January, it does not necessarily mean that the cards will be available or in stock at this time. As soon as any new information or leaks emerge on the Radeon RX 3080, we’ll keep you updated on the blog as always!
