The thread which sometimes talks about RDNA2

From what I can understand Nvidia seems perfectly capable of running DXR 1.1.

Nvidia seem to suggest they themselves support it.

They do, i said that, just as RDNA2 supports DXR 1.0, just not natively given the way AMD are Nvidia run their Shader and RT instructions Asynchronously is entirely different at the architecture level. Read the article i linked, its a quick rundown in the backend code differences.
 
Just noticed AMD sold some 6800 and 6800XT on their website around 3.30pm yesterday according to one of the Discord bots. (French AMD site)
 
I just ordered x5600xt to get me through that madness if i was unsuccessful today and when i manage to get my hands on rx6800xt i will return 5600 as return window is till end of january.
 
They require different code paths, like switches, if you use the switches for DXR 1.0 you're not using the same switches for DXR 1.1 and vice versa, they both work either way but not all the lights are on.
 
IIRC it does technically support it but not optimately due to the changes imposed by 1.1 (same the other way around with AMD and 1.0).

So basically ignore RT performance on any card as the spec is still in flux and constantly changing, so what performs better today might not in the near future.

Yeah, Tho Microsoft drive DXR, its their API and both vendors will align with that now that both vendors have DXR, DXR 1.1 is designed around RDNA2's Async engine, Ampere's replacement will use the same or similar engine.

Nvidia, since the release of Turing and now AMD with release of RDNA2, both have full support for all the Features of Dx12 Ultimate and that includes DXR 1.1.

No, having "Full support" is not the same as "being the same" DirectX Ultimate is simply a set of features, an extraction layer of which DXR is a part of, all support the same features does not equate to being interchangeable between different architectures, Nvidia and AMD are architecturally different and require different codes paths. Think Betamax vs VHS, AMD and Nvidia had different ideas on how RT should be done and have gone down different routs, probably because Microsoft run RT in consoles they have updated some fundamentals from DXR 1.0 to something more efficient resulting in DXR 1.1 which was codeveloped with AMD, that result was RDNA2.

I have no idea if what you are saying will bare out in reality w.r.t future RT performance, but the failure of people to comprehend the point you're making is unsurprising going by the last 20% of this thread. I would just give up with it and revisit in a few months when it's less speculative.
 
Frank azor is likely to be fired from amd at some point.
I never seen someone so clueless about how the market works and customers respond.
TSMC at 7nm and not anyone else able to give wafer is an issue for sure.
and corona virus don't help.
