AMD Radeon RDNA2 Navi (RX 6500, 6600, 6700, 6800, 6900 XT)

I really was trying to understand. My non RT was trying to give the concerns the benefit of the doubt. (maybe I should've gone back a couple pages to catch up)

I'm actually amazed that there would be any question at this moment in time regarding how RDNA2 is going to compare against Ampere when RT is enabled. Hence why I thought people was being crazy to even compare it in that manner.

I'm sorry, but if you think that supporting what was the only RT enabled card available during development, then it turns out to be the more performant cards with the addition of DLSS2 on top. I don't know what to say to you.
Maybe they should've hobbled their game, or only enable RT when RDNA3 is available?

As for questionable benefit at the highest setting, isn't that pretty much every PC game? This obviously goes further than CDPR.

 

Not at all. Just saying that fear mongering without evidence of nefarious activity by CDPR is uncalled for.

 

Yes we needed this. They push cpus hard too.

 

It's tough to run this game with ray-tracing on and higher resolution without dlss. 3070fe dips below 30fps on ultra @1440p even in the beginning which is not as heavy as the city. But you don't need to run ultra or psycho or 1440p/4k necessarily. It's great to have options. 6800xt is likely going to be somewhere around or slower than 3070fe when using ray tracing this heavily. It's going to push memory bandwidth hard and also 6800xt sharing tmu's and compute between shading/ray tracing is not going to help. Dedicated hw is good if there is memory bandwidth to run shading, rasterizing and ray tracing parallel. This is similar to async compute versus no async compute.

 

There's nothing to discuss about non RT performance IMO.
nVidia has an edge mostly because they've most probably had access to earlier code to optimize their GPU drivers. It doesn't mean that AMD can't catch up, especially considering the cards within the same price bracket are already within some ~10% of each other.
We do know CDPR didn't even have any Navi 21 card up until after the cards released, which is when their QA team finally put the RX6800XT in their system requirements.

Who questioned that Ampere has better RT performance than RDNA2? And where?

The only RT enabled cards available during development were the Turing cards. Which are running like crap when all RT effects are turned on. I made that exact point in my previous post.

Define "nefarious". I don't think CDPR puting a bunch of unoptimised brute-forced RT effects into the game by nvidia's request is nefarious. Just like using Hairworks on Witcher 3 with subpixel triangles that brought Kepler and GCN2 cards to their knees.
OTOH, nvidia making those requests...

 

Probably run fine at lower resolution or settings.

The point is you add features and settings that go beyond what is currently available.
As it turns out there are some cards available that can make use of them already. Maybe they should've pushed harder in my eyes.
But I'm a bit of a radical in that way, I'm from the can it run Crysis school of thought for PC. As long as there's reasonable settings for a wide range of configurations.

 

Nefarious would be an implementation that unnecessarily and intentionally harms RDNA performance.

Are you saying that Cyberpunk has a bunch of unoptimized brute force RT effects requested by Nvidia to harm AMD? Since we all agree conspiracy theories are stupid I'm sure you have information to support that position.

Turing seems to be doing fine for a 2 yr old arch based on Tom's numbers.

 

There is big difference in how rt works on amd and nvidia hw. In amd hw rt uses compute(traversal) and tmu's(memory accesses) to do ray tracing. In nvidia hw there is dedicated units. This allows nvidia hw to do better parallel raster, compute and ray trace. This is similar to async compute which gave amd advantage in past but now nvidia has better async computing when using ray tracing. All this of course is memory bandwidth dependent where it looks like nvidia has advantage especially with divergent rays.

 

This is the firat taste of next gen pushing on all fronts, cpu, ray tracing, ssd streaming, raw bandwith, and raw gpu raster power. Dolby atmos audio.
Its no wonder that when you do all of that at once, in a big open world with lots of atuff going on chasing framerates and resolutions.... ye things are going to suffer the longer down the range of hw you go.

Good to see its running/optimized for birg nv and amd at the least.

A ’crysis’ was much needed imo, push everything, instead of forego RT or skip big open areas etc, its what people envisioned, RT in big open worlds with infinite detail in a next gen flavour.
Anyone noticed the particle effects too? These really add to the inmersion.

 

I'm really excited to see how much cdpr can optimize their implementation in future. Now that the tech and game is here rest is polishing it up and optimizing. If they were really crunching the whole year perhaps some work was postponed after launch in effort to ship the game. They could have ideas on how to make things a lot better but didn't have time to refactor or even change implementation drastically. It must be som kind of learning experience, first try rarely is as good as it can get.

 

I'm not questioning whether or not Ampere has better RT performance than RDNA2. The sentence you quoted referred to non-RT performance.

 

These comments are really ironic, considering CDPR willingly collaborated with nVidia to use tessellation x64 for HairWorks in The Witcher 3, which by the way literally looks no different than tessellation x8/x16 at a much lower performance cost on both nVidia and AMD cards, right at the time when nVidia's cards happened to have an edge in tessellation compared to AMD...

But right... "Fear mongering". "Conspiracy theorists".

I am very well aware that just because it happened in the past it does not necessarily mean that it is in fact happening again. But again, to use those labels to just dismiss it as some crazy out there impossible scenario is just shallow. We should all be on the look out for these things, unless, you know, you want another 10 years of no competition where a deliberately questionable implementation would leave no competition in the market and even more hijacked GPU prices.

You have no counter argument other than trying to shame people with spooky words.

Spoiler

No wonder the world is turning into a tyranny, and you're gonna deserve it when it does.

 

Perfect.

Sure we should all be vigilant. But that's not the same as making baseless insinuations.

 

Fair enough. Let's leave it there...

By the way. I'm surprised the game comes with FidelityFX CAS at all...

 

The original post stated "at 1440 and 4k loses to Nvidia.and with ultra settings get smashed". Which means AMD loses to Nvidia at 1440p even without Ultra settings. But the review states quite the opposite.

 

Another couple of benchmarks albeit with similar results:

RT is officially supported in WDL on AMD RT capable GPUs now: https://forums.ubisoft.com/showthread.php/2302093-Title-Update-2-40-Patch-Notes

 

That’s quite a long list of fixes. Must be maddening for QA and devs trying to stabilize these open world titles.

 

Looking forward to seeing the PC benchmarks. Going by the closest one could hit with consoles, AMD GPUs there were at around a 15% deficit to Turing GPUs in otherwise "teraflop to teraflop" comparison (PS5 hit around the same as a 2060 super, which is around 15% slower than a 2070 super in many cases at similar res). Not great but not deal breaking for many. So it'll be interesting to see the difference on PC.

 

What I can say now from my first 10 minutes as a „corpo“ is that Screen Space Reflections Quality on „psycho“ instead of ultra really kills performance on a 6900XT. Walking through the turtorial with full view of the corpo's (very!!!) shiny (!) office, fps go down from 46 fo 32 in 4k with everything else maxed.
