With today’s announcement from Microsoft of DirectX 12 Ultimate, both NVIDIA and AMD are also chiming in to reiterate their support for the new feature set, and to note their involvement in the process. For AMD, DirectX 12 Ultimate goes hand-in-hand with their forthcoming RDNA2 architecture, which will be at the heart of the Xbox Series X console, and will be AMD’s first architecture to support DirectX 12 Ultimate’s new features, such as ray tracing and variable rate shading.
To that end, as part of Microsoft’s overall DirectX Developer Day presentation, AMD is showing off raytracing running on an RDNA2 for the first time in public. Running an AMD-built demo they call “Futuristic City”, the demo incorporates DXR 1.0 and 1.1 features, to produce what can only be described as a very shiny demo.
It should be noted that this demo was a recording – as all of the Microsoft dev day presentations were – though there is little reason to doubt its authenticity. AMD also showed off an RT recording a couple of weeks back for Financial Analyst day, and presumably this is the same trailer.

keep throwing insults, that's all you can do and all you know how to do. BTW you use block quotes ( which don't seem to work on this comment system ), i use quotation marks, same thing, its called quoting someone. you really need to get off your high horse, and get over your self, you are so arrogant, you don't even realize it.
" where in my comments I do ever suggest such a thing? " almost every post you make say it, look, just be cause you claim to understand everything about technology, doesn't mean every one else does. that's why people come to sites like this, they have an interest it technology, and would like to try to learn a little more about it.
so what ever, again, get off your high horse, and get over your self.

The problem is that to gain efficiency AMD has doubled the transistor budget.It did that to try to overcome all GCN limitations. Now RDNA seems a much better architecture than what is was GCN, and actually it is. Unfortunately it comes without ANY of the more advanced features that already are present in Turing.
RDNA has to be compared to Pascal in terms of efficiency and feature richness (or better lack of).
Do a direct comparison and see where AMD is more than 3 years later.

BTW, people like you make me thing to those that wrote everything and anything to try to defend Bulldozer and when Zen came out just understood what is a winning architecture.GCN is the same. It is a loser (even at the fat obese version of RDNA). When AMD will come with a real competitive architecture (which means GCN will be discarded completely as they did with Bulldozer fail) you'll see what that will mean for competitors (and at that time they will be two, not only one).
But for now, RDNA is just a obese GCN that does not go anywhere seen it uses too much transistors and a lot of energy despite the much improved PP. You see, any architecture can be good gived enough transistors and energy. And it is good as much as the performance the competition can achieve with same resources. And when you are not competitive, guess what happens? Yes, they start doing discounts. Sometimes even before actually launching the product.

Not this again...1) Efficiency of RDNA on 7nm is not worse than Turing on 12nm, it's about as even as you get.
2) We already know RDNA 2 is ~50% better on PPW.
3) Absolute nonsense about die sizes there.

Big Navi will almost certainly outperform Turing (series 20xx) but not Ampere (series 30xx). Since Βig Navi will compete against Ampere Nvidia will hold the performance crown for the next round of graphics cards as well. So the status quo will not change.djayjp - Saturday, March 21, 2020 - link
This. But not sure about performance at the same price point.CiccioB - Tuesday, March 24, 2020 - link
Price or costs?Sefem - Saturday, March 21, 2020 - link
On rasterization it's perfectly plausible as they have a full node + of advantage but on ray tracing? that really has to be seenblppt - Thursday, March 19, 2020 - link
Thats my point though---they're (possibly) releasing a GPU that will match or beat a NVIDIA flagship thats been around since late 2018. And 3080ti is releasing soon too.I want another 7970 situation---when it came out, no consumer Nvidia product could match it.

More important AMD win compute, for the sake of their long-term profits. Vulkan Compute will be their only hope realistically, with OpenCL appearing dead in the water.
