The NVIDIA Turing GPU Architecture Deep Dive: Prelude to GeForce RTX
by Nate Oh on September 14, 2018 12:30 PM ESTUnpacking 'RTX', 'NGX', and Game Support
One of the more complicated aspects of GeForce RTX and Turing is not only the 'RTX' branding, but how all of Turing's features are collectively called the NVIDIA RTX platform. To recap, here is a quick list of the separate but similarly named groupings:
- NVIDIA RTX Platform - general platform encompassing all Turing features, including advanced shaders
- NVIDIA RTX Raytracing technology - name for ray tracing technology under RTX platform
- GameWorks Raytracing - raytracing denoiser module for GameWorks SDK
- GeForce RTX - the brand connected with games using NVIDIA RTX real time ray tracing
- GeForce RTX - the brand for graphics cards
For NGX, it technically falls under the RTX platform, and includes Deep Learning Super Sampling (DLSS). Using a deep neural network (DNN) specific to the game and trained on super high quality 64x supersampled images, or 'ground truth' images, DLSS uses tensor cores to infer high quality antialiased results. In the standard mode, DLSS renders at a lower input sample count, typically 2x less but may depend on the game, and then infers a result, which at target resolution is similar quality to TAA result. A DLSS 2X mode exists, where the input is rendered at the final target resolution and then combined with a larger DLSS network.
Fortunately, GFE is not required for NGX features to work, and all the necessary NGX files will be available via the standard Game Ready drivers, though it's not clear how often DNNs for particular games would be updated.
In the case of RTX-OPS, it describes a workload for a frame where both RT and Tensor Cores are utilized; currently, the classic scenario would be with a game with real time ray tracing and DLSS. So by definition, it only accurately measures that type of workload. However, this metric currently does not apply to any game, as DXR has not yet released. For the time being, the metric does not describe performance any publicly available game.
In sum, then the upcoming game support aligns with the following table.

The sites I look at put $649 2013 dollars at about $700 today. They use the CPI, the Consumer Price Index. That is the standard way to compare values over consumer goods and cost of living in general between different years where the CPI has been recorded. I have no idea where the numbers in your chart have come from. For instance, by the CPI, the 7800 GTX 512, which was released in 2005, is about $840 in 2018 dollars, and $825 in 2017 dollars, far more than the $783 listed in your chart.Note that if you have a steady 2% inflation per year over 13 years you get a 29% increase in prices.

And besides, your chart, even with the wrong numbers, doesn't show what you claim to show. The 780, the 280, the 8800 GTX, and the 7800 GTX all have launch prices around the RTX 2080, even though the RTX 2080 has a bigger die than any of them.eddman - Saturday, September 15, 2018 - link
Yes it does. 2080 Ti is the most expensive geforce launch card. It's not my job, as a buyer, to dig up die sizes or even care about them. I only care about performance/price ratios which these cards are terrible at.eddman - Saturday, September 15, 2018 - link
... they are terrible because the price/performance ratio hasn't improved in any substantial way. 1080 Ti offered ~70% performance increase over 980 Ti for just ~8% higher launch MSRP.Yojimbo - Saturday, September 15, 2018 - link
OK, so when GM produced the Hummer that's directly comparable to their Suburban because they were both SUVs. It's not your job to be an intelligent creature and realize that the Hummer opened up a new market segment. Instead, spend your energy resenting GM. You can do what you want but that doesn't make it rational.eddman - Sunday, September 16, 2018 - link
... except a Hummer is a Hummer and a Suburban is a Suburban. They are not part of the same lineup. Also, a car is not a video card.2080 Ti directly follows 1080 Ti based on the naming. It's not my fault they did it. They could've named it 2090 Ti if they really meant it to be a different product category, but they didn't so based on common branding logic 2080 Ti is the successor to 1080 Ti and therefore it is not out-of-the-ordinary to expect close pricing.
Rational? What I wrote is completely rational. It is you who is trying to somehow make it look that a ~42% price jump for a 40%-45% performance increase in regular rasterized games is ok. It is not. This is probably the worst generational price/performance ratio vs. the old gen I've seen.

... unless they plan on releasing GTX 2080 Ti/2080 at lower prices, but given the potential confusion that it might cause, probably not.0ldman79 - Sunday, September 16, 2018 - link
Oddly enough, going by that comparison the H2 is built on the same platform as the Suburban.Killmorefor - Sunday, September 16, 2018 - link
That chart is pretty accurate, but would benefit from a 3D showing price drops after the next gen introduction. The chart apples, and but does not show the price jump before the chart started, nor the current jump for the next gen the OP has very good point.markiz - Monday, September 17, 2018 - link
Yeah, so what?I don't understand.. If the price is too high, they will not sell much.
