Very few people buy at the price point of 1080 and higher on Pascal. Even a smaller minority would entertain the price point of Geforce 20 series. After that fact you're met w/ the insane FPS drop when you enable Ray Tracing.... What exactly is going to result in sales picking up when any...

The only thing RT cores do is intersection tests. Ray generation and the object acceleration structure are computed i cuda cores which takes away resources from pumping higher frame rates. Shading as you correctly state occurs in the traditional shading pipeline. Lastly, the denoising stage of...

The results coming in confirm just about everything people critical of this card were stating and highlights why Nvidia kept mum about it for so long. In the consumerist space, it was clear pre-launch that those intending on buying this card didn't care. So it's a match made in heaven. This is...

This is not indicative of the card sweating. It reflects that the pipeline for processing ray tracing isn't as parallel as they suggested. It indicates that RT cores really aren't doing all that much beyond basic intersection testing. It indicates why Nvidia was so secretive about information...

I agree 100% with what you just established and I think its the more informed/reasoned viewpoint backed by technical facts and an understanding of basic business/profit maximization. At $800/$1200, these are essentially glorified Quadro cards. The lowest entry Quadro was cheaper than $800. They...

Thank you very much for posting this. Going to give it a read ! :yes:

I was sure this is what was referenced with : 10 Gigarays. So, they most likely are referring primary ray generation, traversal, miss and closest hit throughput. When divergence and deeper processing in the pipeline occur is when the troubles and performance issues begin. So, it will be...

Agreed. All is not lost... The "marketing" caused me to dig a lot deeper into how this all functions and I learned an incredible amount. This helps me make a much more informed decision. Without this blackout period, I possible would have bought it blindly. Now I can deeply second guess such a...

You can read and digest something without making the proper reference to every detail especially things that are insignificant to something you're trying to discuss. I'm not discussing the later portions of the hybrid ray tracing pipeline. I'm discussing And where Nvidia got their Ray/sec...

0.5x,1x,2x,3-10x,15x with a million and one variables involved 10 Gigarays Pascal : ~1 Gigaray .. 5.3x = 5.3 Gigarays. Doesn't come up to 10 gigarays. A 2080ti is supposed to be capable of 10 Gigarays So, here's the thing about all the handwaving/and technical details which I do understand...

I've already read the white paper some time ago found here : https://research.nvidia.com/publication/2018-08_Adaptive-Temporal-Antialiasing I get it exactly. I also get what is involved with ray tracing : And where Gigaray/sec figures come from which has nothing to do w/ post processing. I...

Do as you please. I'm an engineer and I am not allowed to do public exhibitions without my slide decks being revised and approved by a slew of people people from marketing as anyone would expect for any well formed company. My commentary has nothing to do w/ Morgan McGuire and everything to do...

Which has nothing to do w/ the raw performance of ray tracing and Gigaray/sec. It's a completely different topic and aspect of the pipeline. NVIDIA DLSS : AI-Powered Anti-Aliasing Adaptive Temporal Antialiasing (ATAA) Spot the difference? Both use tensor cores to get their speedup. Both can...

Suggests comparing a Titan V ($3000) to a Quadro 6000 which costs ($6000) and has 24GB ram. Then gets even more creative and compares a Quadro 6000 to a $400 8GB 1080 Pascal. Speeds are anywhere from 0.5x to 15x and they're all timing related w/ hilarious footnotes detailing that the timings...

DirectX is an API. It is not a Driver. DXR is a component of DirectX's API. It is the component that servers ray tracing. It too is an API There's nothing to discuss or dig into further here. Drivers are written by manufacturer of Hardware so that higher level APIs can access it. In the links...
