AMD Path Tracing Toyshop Demo

[Drash]

AMD posted a realtime path tracing demo for RDNA4

It looks nice, but I'm far from a graphics expert. A site I visit wasn't as impressed https://www.notebookcheck.net/Lackl...rge-gap-with-RTX-50-series-GPUs.971854.0.html but I don't spent gaming time staring at puddles etc.

What do you guy think?

Demo itself is less impressive than what Nvidia has put out recently. Looks quite a bit behind which is probably accurate for what it is. But really, whether that matters is a bit secondary. AMD does have the tech in usable and apparently performant form.

Real games or applications and apples-to-apples comparisons are what will determine if they got on par or not. Visuals of real stuff are not determined by AMD or Nvidia and will put cards from both on equal-ish ground. Remains to be seen how implementation of all the custom tech like neural rendering or ray reconstruction will end up happening. Now that there is more than one real player, some standardization would be nice?

The thing that hit me from the video Ozzer posted was that, yeah, the NVidia marble video was awesome, but they've got £2000+++ hardware to play that (plus more software tricks). AMD just has a 9070XT, which is in my price range. I still think a lot of RT is just NV trying to hammer AMD because they can, rather than RT being something we absolutely need.

When the 4090 came out it seemed like the card to last forever as it was so damn powerful and so ahead of everything else, but then NV NVidia-ed themselves by bringing out path tracing which immediately hammered the 4090. Lol. That's changed how I view the xx90 cards (and NV), not for the better.

Marbles? Wasn't that Turing demo that ran on a high-end Quadro? That would be a bit faster than 2080Ti which in more recent generations is the performance range of 3070/Ti or 4060Ti/4070 or 7800XT.

It was the same story with sli, physx, hairworks, tesselation, gsync, dlss... Planned obsolescence.

I'll be honest, I can't make out the imperfections that other people are seeing. The soft image is basically the only thing that stood out to me. I suspect that once reviewers boot up Cyberpunk and compare path-tracing properly it will be a marginal difference. NVIDIA will likely come out ahead of course but if we're zooming in to find differences then I'd consider that a job well done for AMD. They can only get better.

You're right 2020 - I didn't catch that!

OK so NV have quite a large lead but they're pushing RT with the big guns - 5090 is silly expensive and it made the 4090 (which was also silly expensive) look decidely not good enough in a year or so. AMD have nothing in that range, so NV is maybe pushing boundaries, but who's winning? RT is still a long way from being universally available.

Yeah. Haven't missed them (970 was last NV card I had). I now think spending too much is a fools errand as something, possibly unexpected or from a tangent, comes along that suddenly makes what you have seem meh. Flagship wow is great to dream about, and helps all the content providers, but...

Spending £2k on a series of gfx cards over a period of 10 years (?) seems a better bet than buying a 5090 and clinging on for dear life hoping for the best.

I think I'm happy I look at these demos and say "wow" and dont really see all the bad things. I liked this toyshop demo. I hope 9070XT does well.

What? Come on, you know better than that. And none of these are an example of planned obsolescence. Either the feature fell out of favor or became a standard, neither of which even resembles planned absolescence.
- SLI/CF died because of increasing maintenance costs for IHVs and theoretical promise of more inherent replacement in form of DX12 multi-gpu.
- For PhysX Nvidia tried to hold on to GPU-accelerated version of it by hampering the CPU version. They gave up and PhysX is still pretty widely used, just usually not running on GPUs. A major factor in this was also the rise of multi-core CPUs that were no longer that bad in physics calculations.
- Hairworks or a successor of that is still in Gameworks. Plus it was joined by other implementations of hair rendering - TressFX was maybe the most prominent one going through the news. But hair rendering as once a "special" technology went into mainstream and is part of various engines or (physics) middlewares these days.
- Tessellation is just mainstream. It is a standard thing and used all over the place. Btw, tessellation came out first as an ATi (now AMD) innovation.
- Other than a marketing thing, GSync came out a good 1.5 years ahead of FreeSync and more than that before things got on par - arguably. Now Adaptive sync is a standard feature and basically implemented on scaler level in almost any monitor that needs it. But that took long years to happen.
- Not sure what you mean by DLSS. Newer versions or features like MFG limited to newer generations? There does seem to be a technical reason for most of that. And it is not usually the "cannot run" that Nvidia hints at and understanding veers towards, it is older cards not being able to run the thing without an oversized performance hit.

The ontopic feature of raytracing is quite different from these things from get-go. DXR is part of Microsoft DX12 as standard from the beginning. Vulkan took a bit longer but also has ray-tracing in API as standard thing. Implementations can and should vary.

The only thing I can conclude from comparing this tech demo to Nvidia's is that I like NV's artists' work better. Which is irrelevant to the actual technical prowess being demoed here...

Isn't most of the blurring people complaining about from intentional motion blur and DoF?

The biggest problem I can see quite apparently is ghosting, which is different than motion blur. If you watch the robot's arm, it's pretty apparent where a whole trail exists where it used to be:

There's some blurriness on the green of the "shoulder" for example that seems like motion blur, but that trailing effect behind anything that moves looks exactly like what you see with bad DLSS/FSR implementations.
