Update 6: AMD Radeon RX 5000: New Navi Graphics Cards Introduced!


The Radeon RX 5700 XT and the Radeon RX 5700 from AMD represent two new gaming-oriented graphics cards. Based on the new RDNA microarchitecture, both graphics cards are part of the upper mid-range Navi-based segment. At AMD's E3 Technical Press Event the Texas-based chip manufacturer took the opportunity to present their new generation of graphics cards.

The Radeon RX 5000 series is based on the Navi graphics chip, the architecture of which seems to be built on a combination of the RDNA- and GCN architecture. The Radeon RX 5700 (XT) is manufactured using the new 7nm node. Another welcome arrival was the support for PCIe 4.0 as well as support for DisplayPort 1.4 with DSC compression, along with the newest iteration of the Radeon Media Engine. This enables 4K decoding at up to 150 FPS thanks to the implementation of the H.264 codec.

The Radeon RX 5700 (XT) will be available from July 7th in the reference design. The AIB cooler designs are expected to begin arriving in August. AMD continues to opt for radial-style cooler designs, presumably to avoid competing directly with their AIB partners. The reference design also appears to be designed with overclocking in mind. More information is available at AMD's website (external link).

Update 5: AMD Radeon RX 5000: New Navi Graphics Cards Announced


In addition to the Ryzen 3000 CPUs announced at the keynote event at Computex 2019 courtesy of AMD's CEO Lisa Su, the subject of new AMD graphics cards also came up. Various specialist publications like Computerbase.de (external link) and wccftech.com (external link) have already summarised the keynote.

Needless to say, a few big surprises emerged, one of which includes a new series of "Radeon RX 5000" graphics cards. We've regularly speculated about a possible 3000- series on these pages, a series that would run in tandem with the Ryzen 3000- series. Other rumours emerged that Navi would be based on the GCN architecture. Navi seems to be based on the RDNA architecture - short for Radeon DNA. Navi would then be the first generation of RDNA- based architecture.

AMD will likely relesae more info about the new gaming graphics cards at the E3 gaming exhibition. It has also become clear in the meantime that the RDNA architecture offers better performance in games when compared to GCN architecture, as well as higher clock frequencies and improved energy efficiency. As in the case of the new Ryzen processors and the motherboards that go alongside them, the Radeon RX 5000 series will be compatible with PCIe 4.0. The Navi-based graphics cards are rumoured to be on their way for some time in July.


Update 4: Specifications of the Radeon RX 3000 Series Leaked?


Over the course of Computex at the end of May, reports are steadily trickling in that AMD is planning to show off their new Radeon RX graphics cards. The Radeon RX 3000-series looks to be based on the new Navi GPU architecture and use the 7nm node, with the Ryzen 3000- series CPUs likely launching on 7.07.2019. The first generation of Navi graphics cards will be built on the Navi 10- chip, to be followed up one year later with Navi 20- graphics cards. The experts at wccftech.com (external link) have combined the latest speculations and rumours to come up with some potential specifications for us to look forward to.

While the Navi 20 chip seems to have had a more rocky development process, Navi 10- series GPUs seem to have remained unaffected. Since Navi 20 is primarily for use on professional graphics cards in the Radeon Instinct series, gaming graphics cards like the Radeon RX 3080 which use Navi 10 have enjoyed a smooth development process and there seems to be nothing remaining in the way of a June launch.

We’ve collected together the rumoured specifications of the new AMD graphics cards in the table below. As such, the Navi 10 chip on the Radeon RX 3080 should provide 52 Compute Units (CUs) combined with 8 GB GDDR6-VRAM. With a TDP of 175 Watts, the card should provide around ten percent more performance than the Radeon RX Vega 64.

Update 3: AMD Navi Graphics Cards Retain GCN Architecture?


Over the course of the Easter holidays, the rumour mill has gone into overdrive once again and with just four weeks to Computex, new information on AMD's Radeon RX 3080 has emerged. At least this seems to be the case according to the experts at wccftech.com (external link), who appear to have stumbled across extra info on the new Navi architecture. The tech bloggers at Phoronix also appear to have discovered an entry with the term GFX1010 that seems to point to the new Navi series of graphics cards.

What is more interesting here however, is that the entry retains the AMDGCN prefix. This would seem to indicate that the Navi architecture is based on AMD's Graphics Core Next architecture. This is primarily of interest due to the fact that the GCN architecture seems to be limited to 4096 Streaming Processors. Consequently, any performance increase of the Radeon RX 3080 in comparison to the RX 590 and other Polaris-series cards would seem to be due to switching over to the new 7nm manufacturing process as well as optimisations in the GPU architecture.

Included among these optimisations is the exciting deployment of GDDR6-VRAM. Computerbase.de (external link) has some leaked pictures of the Navi PCB. The PCB of what we assume to be the Radeon RX 3080 would seem to include, among other updates, eight memory chips that are connected to the GPU by means of a 256-Bit memory interface. This would also indicate that the card may bring up to 16GB of VRAM to the table due to each chip being limited to a maximum of 2GB.

AMD is expected to introduce the Radeon RX 3080 as well as additional Navi-based graphics cards at Computex 2019. The release date of the new AMD graphics cards is thought to be 7.07.2019. The 7nm graphics cards will presumably arrive alongside the AMD Ryzen 3000-series CPUs.


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!
